Panetta Orders Deployment of U.S. Antimissile Units in Turkey

In a part of Aleppo controlled by the Free Syrian Army, a woman hurt by Syrian Army shelling was wheeled in front of a hospital.

INCIRLIK AIR BASE, Turkey — Defense Secretary Leon E. Panetta signed an official deployment order on Friday to send 400 American military personnel and two Patriot air defense batteries to Turkey as its tensions intensify with neighboring Syria, where government forces have increasingly resorted to aerial attacks, including the use of ballistic missiles, to fight a spreading insurgency.

The American batteries will be part of a broader push to strengthen Turkey’s defenses that will include the deployment of four other Patriot batteries — two from Germany and two from the Netherlands. Each battery contains multiple rounds of guided missiles that can intercept and destroy other missiles and hostile aircraft flying at high speeds.

Mr. Panetta’s deployment order, the result of NATO discussions last week, represents the most direct American military action so far to help contain the Syrian conflict and minimize its risk of spilling across the 550-mile border with Turkey, a NATO member that is housing more than 100,000 Syrian refugees and providing aid to the Syrian rebels trying to oust President Bashar al-Assad.

Tensions between Turkey and Syria have escalated in recent months as Syrian forces have bombed rebel positions along the border and occasionally lobbed artillery rounds into Turkish territory. The Turks have also grown increasingly alarmed that Mr. Assad’s forces could fire missiles into Turkey.

News of the Patriot deployment order came as antigovernment activists inside Syria reported new mayhem, including an unconfirmed rebel claim to have shot down a government warplane attacking insurgent positions near the international airport in Damascus, the capital.

In Moscow, meanwhile, the Russian Foreign Ministry sought to distance itself from comments a day earlier by its Middle East envoy that the Syrian rebels might defeat Mr. Assad, a longstanding Kremlin ally and arms client. A ministry spokesman, Aleksandr K. Lukashevich, said Russia remained committed to a political solution in Syria.

“We have never changed our position and will not change it,” Mr. Lukashevich said. He rejected a comment made by a State Department spokesman on Thursday that Moscow had “woken up” and changed its position as dynamics shifted on the battlefield, saying, “We have never been asleep.”

All six Patriot units deployed in Turkey will be under NATO’s command and are scheduled to be operational by the end of January, according to officials in Washington.

George Little, the Pentagon spokesman, said Mr. Panetta signed the order as he flew from Afghanistan to this air base in southern Turkey, close to the Syrian border.

“The United States has been supporting Turkey in its efforts to defend itself,” Mr. Little said.

The order “will deploy some 400 U.S. personnel to Turkey to support two Patriot missile batteries,” Mr. Little added, and the personnel and Patriot batteries will arrive in Turkey in the coming weeks. He did not specify their deployment locations.

After landing at Incirlik on Friday, Mr. Panetta told a gathering of American Air Force personnel of his decision to deploy the Patriots.

He said the United States was working with Turkey, Jordan and Israel to monitor Syria’s stockpiles of chemical weapons, and warned of “serious consequences” if Syria used them, but he did not offer any specifics.

“We have drawn up plans for presenting to the president,” Mr. Panetta said. “We have to be ready.”

Turkey’s worries about vulnerability to Syrian missiles, including Scuds that might be tipped with chemical weapons, were heightened recently by intelligence reports that Syrian troops had mixed small amounts of precursor chemicals for sarin, a deadly nerve gas, at one or two storage sites, and loaded them into artillery shells and airplane bombs. “Their arsenal of chemical weapons has been configured for use at a moment’s notice,” Representative Mike Rogers, a Michigan Republican who heads the House Intelligence Committee, said in an interview on Friday. Mr. Panetta, however, said this week that intelligence about chemical weapons activity in Syria had “leveled off.”

Recent Scud missile attacks by Mr. Assad’s forces against rebels in northern Syria have only added to Turkey’s concerns. The Scud missiles were armed with conventional warheads, but the attacks showed that the Assad government was prepared to use missiles as it struggled to slow rebel gains.

With the nearly two-year-old Syrian conflict entering its second winter and many thousands of people struggling for food and warmth in cities ruined by protracted fighting, the humanitarian costs seemed to be mounting.

An activist in the central province Homs, who identified himself as Abu Ourouba, said the town of Houla — where, the United Nations confirmed in May, Syrian troops had killed more than 100 people, including 32 children — was facing catastrophe.

“Houla has been besieged from all directions for the past 10 days,” he said. “Until now, not even one loaf of bread has entered Houla. The food that was available is beginning to run out very quickly. Most children don’t have milk anymore. The kids are at risk of dying from hunger.”

Shelling along access routes means that no one can walk “unless they crawl” to avoid hundreds of strikes from tanks, warplanes and rocket launchers, the activist said.

The New Old Age Blog: Hospital Alarms Fail to Prevent Injury, Study Finds

When it comes to protecting older people from falls, it can take a long time to figure out what helps and sometimes an even longer time to take action against things that were supposed to help but don’t.

A case in point: the so-called safety rails on hospital and nursing home beds. Their hazards, as The New Old Age reported more than two years ago, are well documented. They are intended to keep sick, drugged or confused people from climbing or falling out of bed. What they actually do is make falls more dangerous; they also trap patients between the rails and the mattress until they asphyxiate, causing hundreds of deaths annually.

The Consumer Product Safety Commission is finally investigating these hazards, with findings due soon.

Alarms — sensors that alert aides or nurses when someone at risk of falling attempts to get out of bed or up from a chair or toilet — sound better, right? Lots of health care facilities thought so.

Use of these alarms has increased “over the past 10 or 15 years as the problems of physical restraints and bed rails became better known,” said Ronald Shorr, who directs geriatric research at the V.A. Medical Center in Gainesville, Fla. “This was the next wave in fall prevention.”

The trouble is, hospital bed alarms don’t appear to reduce falls, according to the study that Dr. Shorr just published in The Annals of Internal Medicine.

Lots of patients, of all ages, fall in hospitals, and about a quarter of those falls cause injuries. They also cost hospitals money, because Medicare will no longer reimburse facilities for treating injuries from falls that in theory shouldn’t have happened.

Though there aren’t statistics on the number of systems, it is rare these days to find a large hospital that doesn’t use alarms, in some cases built right into the beds.

Yet “their efficacy hadn’t been established,” Dr. Shorr told me in an interview. The few studies that reported reduced falls from alarms were small, lacked control groups, or didn’t continue for very long. Dr. Shorr and his colleagues set out to remedy those shortcomings.

Over 18 months, they documented falls among patients in 16 medical and surgical units, with a combined 349 beds, at Methodist Healthcare-University Hospital in Memphis, Tenn. Half those units were randomly designated “usual care.” In the other eight, the “intervention” units, Dr. Shorr and study coordinator Michelle Chandler held repeated education sessions to explain the alarms — in this case, flexible pads made by Bed-Ex and widely-used — and demonstrate their use in beds and on chairs and commode seats.

Ms. Chandler visited the intervention units daily — the staff started calling her “Mrs. Falls” — and even brought fresh alarm pads and help set them up to encourage their use.

The intervention worked, in that those units used the alarms far more often. But when the researchers tallied up the falls among the 27,672 patients (half of them over age 63) in these units — controlling for many variables, including not only demographic factors but staffing levels and psychotropic drug regimens — they found the alarms had no significant effect.

Patients in the units that used alarms more heavily fell just as often as patients in the control units that used alarms much less frequently. (The numbers: 5.62 falls per 1,000 patient-days, a measure of how many people spent how long in the hospital, versus 4.56 falls in the control units, not a statistically significant difference.)

There were no fewer injuries in the more-alarmed units, nor any less use of physical restraints.

There were likely higher costs, though. A Bed-Ex monitor and cables cost about $350 at the time, and each disposable sensor pad cost $23.

Why didn’t the alarms help? Dr. Shorr hypothesized that the staff developed what he called alarm fatigue. “How many times a week do you hear a car alarm go off?” he asked. “You become desensitized.”

But it is also possible, he said, that when the alarms sounded and the nurses scampered, “the patients who weren’t alarmed fell more often.”

My own 2 cents: If an alarm sounds when someone stirs, is any hospital or nursing home so well-staffed that someone can materialize within seconds? Does a staff become less vigilant when patients have alarms and are presumed – wrongly, it seems – to be safer?

Nursing homes also frequently use alarms, and while this hospital data might not apply in another setting, Dr. Shorr said his findings made him skeptical about their effectiveness there, too.

So we probably shouldn’t feel reassured about our elders’ safety when they are in a hospital, alarms or no alarms. Even younger people, recovering from surgery and feeling the effects of anesthesia or sedatives, can and do fall.

“The more eyes on your loved one, the better,” said Dr. Shorr. “And it’s best if they’re your eyes.”

Panetta Orders Deployment of U.S. Anti-Missile Units in Turkey

INCIRLIK AIR BASE, Turkey — Defense Secretary Leon E. Panetta signed an official deployment order on Friday to send 400 American military personnel and two Patriot air defense batteries to Turkey as cross-border tensions with Syria intensify.

The American batteries will be part of a broader push to beef up Turkey’s defenses that will also include the deployment of four other Patriot batteries — two from Germany and two from the Netherlands.

All six units will be under NATO’s command and control and are scheduled to be operational by the end of January, according to officials in Washington.

George Little, the Pentagon spokesman, said Mr. Panetta signed the order as he flew from Afghanistan to this air base in southern Turkey, close to the border with Syria.

“The United States has been supporting Turkey in its efforts to defend itself,” Mr. Little said.

The order “will deploy some 400 U.S. personnel to Turkey to support two Patriot missile batteries,” Mr. Little added, and the personnel and Patriot batteries will arrive in Turkey “in coming weeks.” He did not disclose where the Patriots would be located.

After landing at Incirlik Friday, Mr. Panetta told a gathering of American Air Force personnel of his decision to deploy the Patriots.

He said the United States was working with Turkey, Jordan and Israel to monitor Syria's stockpiles of chemical weapons, and warned of "serious consequences" if Syria used them, but he did not offer any specifics.

"We have drawn up plans for presenting to the president," Mr. Panetta said. "We have to be ready."

Turkey, which has been supporting the Syrian opposition to President Bashar al-Assad, has been worried it is vulnerable to Syrian missiles, including Scuds that might be tipped with chemical weapons. Those concerns were heightened by reports of increased activity at some of Syria’s chemical sites, though Mr. Panetta said this week that intelligence about chemical weapons activity in Syria had “leveled off.”

The recent Scud missile attacks mounted by forces loyal to Mr. Assad against rebels in northern Syria have only added to Turkey’s concerns. The Scud missiles fired at the rebels were armed with conventional warheads, but the attacks showed that the Assad government is prepared to use missiles as it struggles to slow rebel gains.

Syria denied Thursday that it had fired Scud missiles this week. But NATO’s secretary general, Anders Fogh Rasmussen, said that the intelligence gathered by the alliance indicated that they were Scud-type missiles. “In general, I think the regime in Damascus is approaching collapse,” he said. “I think now it’s only a question of time.”

NATO foreign ministers last week endorsed the decision to send Patriot batteries to Turkey. The details of how many each nation would send were not worked out until this week, officials said.

In preparation for the deployment, allied officials had conducted surveys of 10 potential sites, mostly in southeastern Turkey, that could be defended by one or more Patriot batteries.

But NATO nations do not have enough batteries to cover all of the sites. With tensions building with Iran and North Korea defying the United States and its Asian allies by launching a long-range rocket, American officials did not want to send more than a few Patriot batteries to Turkey, especially since it is not clear how long they will be needed.

But NATO diplomats said that the goal was to show enough of a commitment to Turkey’s defense to deter a Syrian attack.

It will take three weeks to ship and deploy the two American Patriot batteries, a Defense Department official said.

One allied official said it might be possible to speed up the deployment of the German and Dutch batteries if necessary. Each of those nations will also send up to 400 troops.

The United States, Germany and the Netherlands are the only NATO members that have the advanced PAC-3 Patriot system.

The Patriot batteries in Turkey will be linked to NATO’s air-defense system. The response by the missile batteries would be nearly automatic, firing interceptor missiles to destroy the target by ramming into it, a tactic the military calls “hit to kill.”

Thom Shanker reported from Incirlik Air Base, Turkey, and Eric Schmitt and Michael R. Gordon from Washington.

DealBook: Sprint Looks to Buy Remaining Stake in Clearwire for $2.1 Billion

Sprint Nextel is ready to flex its new financial muscle.

After striking a partnership with the deep-pocketed SoftBank, Sprint Nextel is moving to secure access to a big chunk of spectrum. On Thursday, Sprint offered to buy the remaining stake in Clearwire for roughly $2.1 billion, a deal will helps bolster its spectrum.

Under the terms of the deal, Sprint is offering $2.90 a share for Clearwire, according to a regulatory filing. The bid by Sprint, which currently owns a 51.7 percent stake in Clearwire, will value the company at more than $4 billion.

Sprint is bulking up in the face of rising industry competition.

In early October, T-Mobile USA announced plans to merge with a smaller network operator, MetroPCS. The combined company will have 42.5 million users, making it a closer competitor to Sprint, the No. 3 carrier.

Shortly after the T-Mobile deal, Sprint bolstered its own resources. In mid October, Sprint sold a majority stake to SoftBank of Japan for $20.1 billion. With the deal, Sprint gained a well-funded partner to help finance the expansion of its network and pursue acquisitions.

“SoftBank brings so much more to Sprint than money,” Daniel R. Hesse, Sprint’s chief executive, said at the time. “This investment provides the opportunity to benefit from the knowledge and expertise of a leader in mobile Internet technology with a proven track record of challenging larger incumbent carriers.”

Almost immediately, speculation mounted that Sprint would seek to buy Clearwire. Shares of Clearwire jumped on the day the deal with SoftBank was announced, as investors bet its strategies would be closely aligned.

A couple days later, Sprint increased its holdings in Clearwire, buying shares from Craig O. McCaw’s Eagle River Holdings. With the transaction, Sprint gained a majority stake in the company.

Now, Sprint wants to buy the whole thing.

It’s part of the company’s greater ambitions to build out its next generation Long Term Evolution network. Sprint has already been converting its infrastructure, and the deal with Clearwire could help accelerate those efforts.

Another Look at a Drink Ingredient, Brominated Vegetable Oil

James Edward Bates for The New York Times

Sarah Kavanagh, 15, of Hattiesburg, Miss., started an online petition asking PepsiCo to change Gatorade’s formula.

Sarah Kavanagh and her little brother were looking forward to the bottles of Gatorade they had put in the refrigerator after playing outdoors one hot, humid afternoon last month in Hattiesburg, Miss.

But before she took a sip, Sarah, a dedicated vegetarian, did what she often does and checked the label to make sure no animal products were in the drink. One ingredient, brominated vegetable oil, caught her eye.

“I knew it probably wasn’t from an animal because it had vegetable in the name, but I still wanted to know what it was, so I Googled it,” Ms. Kavanagh said. “A page popped up with a long list of possible side effects, including neurological disorders and altered thyroid hormones. I didn’t expect that.”

She threw the product away and started a petition on Change.org, a nonprofit Web site, that has almost 200,000 signatures. Ms. Kavanagh, 15, hopes her campaign will persuade PepsiCo, Gatorade’s maker, to consider changing the drink’s formulation.

Jeff Dahncke, a spokesman for PepsiCo, noted that brominated vegetable oil had been deemed safe for consumption by federal regulators. “As standard practice, we constantly evaluate our formulas and ingredients to ensure they comply with federal regulations and meet the high quality standards our consumers and athletes expect — from functionality to great taste,” he said in an e-mail.

In fact, about 10 percent of drinks sold in the United States contain brominated vegetable oil, including Mountain Dew, also made by PepsiCo; Powerade, Fanta Orange and Fresca from Coca-Cola; and Squirt and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.

The ingredient is added often to citrus drinks to help keep the fruit flavoring evenly distributed; without it, the flavoring would separate.

Use of the substance in the United States has been debated for more than three decades, so Ms. Kavanagh’s campaign most likely is quixotic. But the European Union has long banned the substance from foods, requiring use of other ingredients. Japan recently moved to do the same.

“B.V.O. is banned other places in the world, so these companies already have a replacement for it,” Ms. Kavanagh said. “I don’t see why they don’t just make the switch.” To that, companies say the switch would be too costly.

The renewed debate, which has brought attention to the arcane world of additive regulation, comes as consumers show increasing interest in food ingredients and have new tools to learn about them. Walmart’s app, for instance, allows access to lists of ingredients in foods in its stores.

Brominated vegetable oil contains bromine, the element found in brominated flame retardants, used in things like upholstered furniture and children’s products. Research has found brominate flame retardants building up in the body and breast milk, and animal and some human studies have linked them to neurological impairment, reduced fertility, changes in thyroid hormones and puberty at an earlier age.

Limited studies of the effects of brominated vegetable oil in animals and in humans found buildups of bromine in fatty tissues. Rats that ingested large quantities of the substance in their diets developed heart lesions.

Its use in foods dates to the 1930s, well before Congress amended the Food, Drug and Cosmetic Act to add regulation of new food additives to the responsibilities of the Food and Drug Administration. But Congress exempted two groups of additives, those already sanctioned by the F.D.A. or the Department of Agriculture, or those experts deemed “generally recognized as safe.”

The second exemption created what Tom Neltner, director of the Pew Charitable Trusts’ food additives project, a three-year investigation into how food additives are regulated, calls “the loophole that swallowed the law.” A company can create a new additive, publish safety data about it on its Web site and pay a law firm or consulting firm to vet it to establish it as “generally recognized as safe” — without ever notifying the F.D.A., Mr. Neltner said.

About 10,000 chemicals are allowed to be added to foods, about 3,000 of which have never been reviewed for safety by the F.D.A., according to Pew’s research. Of those, about 1,000 never come before the F.D.A. unless someone has a problem with them; they are declared safe by a company and its handpicked advisers.

“I worked on the industrial and consumer products side of things in the past, and if you take a new chemical and put it into, say, a tennis racket, you have to notify the E.P.A. before you put it in,” Mr. Neltner said, referring to the Environmental Protection Agency. “But if you put it into food and can document it as recognized as safe by someone expert, you don’t have to tell the F.D.A.”

Gadgetwise Blog: Q&A: Getting YouTube on the TV Screen

How do you play YouTube videos on TV if you don’t have an iPad or an Apple TV?

Getting YouTube to play on the TV depends on the hardware you have. If you have a computer, you can connect it to the TV with compatible audio-video cables (just like you would a DVD player) and then switch the display input source on the TV to the computer. You can then select and play the YouTube videos on the computer and watch on the connected TV screen.

The exact cables you need for this depend on what connections are on your TV and computer. If you have fairly new devices, you might be able to link the computer to the TV with an HDMI cable. For older gear, VGA and audio cables can connect the two, as long as your computer’s video card can handle it. To see what you need, check the audio and video ports on the back of both the TV and the computer and buy matching cables.

YouTube is so popular that it has turned up on a number of other devices besides the Apple TV. Some TiVo video recorders offer a built-in YouTube channel, as does the Boxee Box and Google TV devices, among many others.

Russian Envoy Says Syrian Leader Is Losing Control

MOSCOW — Deputy Foreign Minister Mikhail Bogdanov, Russia’s top envoy for Syria, said on Thursday that President Bashar al-Assad’s government was losing control of the country and might be defeated by rebel forces.

“Unfortunately, it is impossible to exclude a victory of the Syrian opposition,” he said — the clearest indication to date that Russia believed Mr. Assad, a longtime strategic ally, could lose in a civil war that has claimed tens of thousands of lives.

“We must look squarely at the facts and the trend now suggests that the regime and the government in Syria are losing more and more control and more and more territory,” said Mr. Bogdanov, in remarks to Russia’s Public Chamber carried by Russian news agencies.

Russia, Mr. Bogdanov said, is preparing to evacuate its citizens — a complex task, since for decades, Russian women have married Syrian men sent to study in Russia and returned home with them to raise families. It was the first time an official at Mr. Bogdanov’s level had announced plans for an evacuation, which sent a clear message to Damascus that Russia no longer holds out hope that the government can prevail.

As the Russian official spoke, fresh evidence emerge of the intensity of the battle and its proximity to the capital, Damascus.

Syrian state media and anti-government activists reported that at least 16 people had been killed when a car bomb exploded near a school in the town of Qatana, southwest of the capital, on Thursday.

The bomb wounded more than 20 people, leaving some in critical condition, according to the Syrian Observatory for Human Rights, which tracks the conflict through a network of activists. Government forces still hold sway in Qatana, a town with a Sunni Muslim majority and Christian minority, Agence France-Presse reported.

The number of car bombs in residential areas appears to have increased in recent weeks, hitting neighborhoods perceived as housing many government supporters as well as others considered sympathetic to the uprising.

Agence France-Press also reported that Interior Minister Mohamed Ibrahim al-Shaar was wounded in a bomb attack on his ministry on Wednesday. But he was not seriously hurt, the agency said, quoting an unidentified security source who said that the bombing was believed to have been carried out by a saboteur because only official vehicles can approach the building.

Mr. Shaar was injured in an earlier bombing on July 18 that killed four senior security officials at a Damascus headquarters. Russia is eager to protect its strategic interests in Syria, including a naval facility at the port of Tartus, and has been meeting frequently with opposition delegations, presumably laying the groundwork for a possible transition. In his remarks to the Public Chamber, a Kremlin advisory group, Mr. Bogdanov said he believed that half the Russian citizens living in Syria support the rebels.

“Moreover, some of the people coming here as part of opposition coalitions have Russian passports,” he said.

Russia has cast its stance on Syria as a principled stand against Western-led intervention — a passionate topic for President Vladimir V. Putin, who feels Russia was deceived into supporting a no-fly zone in Libya that ultimately led to a military campaign that led to the overthrow of Col. Moammar el-Qadaffi. In recent days, Moscow has been adamant that its fundamental position has not changed.

For many months, the Russian authorities have resisted Western pressure on Moscow to persuade the Syrian leader to step down. Though Russia has said it supports the creation of a transitional government, it has been at odds with the West on whether Mr. Assad — and his ally Iran — would have a voice in it.

Mr. Bogdanov said on Thursday that Russia’s stance has been deliberately distorted in the Western media, an effort “intended to weaken our influence” in the Middle East, and that third-party governments have strengthened rebel forces by providing weapons.

“Massive supply of modern armaments have pushed the Syrian rebels to stake their hopes on force,” leading to “an acceleration of the spiral of violence,” he said.

Leonid Medvedko, a political analyst who covered Syria for Soviet news services, said officials have so far been reluctant to declare an evacuation of Russian citizens “because there are technical questions, political questions — because it will mean we are fully giving up Syria.”

“It is a humanitarian step, but each humanitarian step has a political meaning,” he said.

From the first, Russia has taken the view that Mr. Assad’s departure would usher in a long and chaotic process of fragmentation in Syria, but most experts this week said they were braced for the beginning of that process. Mr. Medvedko, the former journalist, said he expected Syria to split into four parts that would be home to distinct ethnic and religious groups, much as Yugoslavia did in the 1990s.

Fyodor Lukyanov, the editor of Russia in Global Affairs and head of an influential policy group, said that even if Mr. Assad left the country, his countrymen will keep fighting.

“The prevailing view is that it will be complete and desperate chaos,” said Mr. Lukyanov. “To remove Assad will not mean settlement of the Syrian conflict. You can remove him — I don’t know in which way — but what will you do to 300,000 Alawites? They will be fighting for their lives, not for power anymore,” he said, referring to the minority sect that rules the country.

The New Old Age Blog: The Gift of Reading

This is the year of the tablet, David Pogue of The Times has told us, and that may be good news for seniors who open holiday wrappings to find one tucked inside. They see better with tablets’ adjustable type size, new research shows. Reading becomes easier again.

This may seem obvious — find me someone over 40 who doesn’t see better when fonts are larger — but it’s the business of science to test our assumptions.

Dr. Daniel Roth, an eye specialist and clinical associate professor at the Robert Wood Johnson Medical School in New Brunswick, N.J., offered new evidence of tablets’ potential benefits last month at the annual meeting of the American Academy of Ophthalmology.

His findings, based on tests conducted with 66 adults age 50 and over: older people read faster (a mean reading speed of 128 words per minute) when using an iPad, compared to a newspaper with the same 10-point font size (114 words per minute).

When the font was increased to 18 points — easy to do on an iPad — reading speed increased to 137 words per minute.

“If you read more slowly, it’s tedious,” Dr. Roth said, explaining why reading speed is important. “If you can read more fluidly, it’s more comfortable.”

What makes the real difference, Dr. Roth theorizes, is tablets’ illuminated screen, which heightens contrast between words and the background on which they sit.

Contrast sensitivity — the visual ability to differentiate between foreground and background information — becomes poorer as we age, as does the ability to discriminate fine visual detail, notes Dr. Kevin Paterson, a psychologist at the University of Leicester, who recently published a separate study on why older people struggle to read fine print.

“There are several explanations for the loss of sensitivity to fine detail that occurs with older age,” Dr. Paterson explained in an e-mail. “This may be due to greater opacity of the fluid in the eye, which will scatter incoming light and reduce the quality of the projection of light onto the retina. It’s also hypothesized that changes in neural transmission affect the processing of fine visual detail.”

Combine these changes with a greater prevalence of eye conditions like macular degeneration and diabetic retinopathy in older adults, and you get millions of people who cannot easily do what they have done all their lives — read and stay connected to the world of ideas, imagination and human experience.

“The No. 1 complaint I get from older patients is that they love to read but can’t, and this really bothers them,” Dr. Roth said. The main option has been magnifying glasses, which many people find cumbersome and inconvenient.

Some words of caution are in order. First, Dr. Roth’s study has not been published yet; it was presented as a poster at the scientific meeting and publicized by the academy, but it has not yet gone through comprehensive, rigorous peer review.

Second, Dr. Roth’s study was completed before the newest wave of tablets from Microsoft, Google, Samsung and others became available. The doctor made no attempt to compare different products, with one exception. In the second part of his study, he compared results for the iPad with those for a Kindle. But it was not an apples to apples comparison, because the Kindle did not have a back-lit screen.

This section of his study involved 100 adults age 50 and older who read materials in a book, on an iPad and on the Kindle. Book readers recorded a mean reading speed of 187 words per minute when the font size was set at 12; Kindle readers clocked in at 196 words per minute and iPad readers at 224 words per minute at the same type size. Reading speed improved even more drastically for a subset of adults with the poorest vision.

Again, Apple’s product came out on top, but that should not be taken as evidence that it is superior to other tablets with back-lit screens and adjustable font sizes. Both the eye academy and Dr. Roth assert that they have no financial relationship with Apple. My attempts to get in touch with the company were not successful.

A final cautionary note should be sounded. Some older adults find digital technology baffling and simply do not feel comfortable using it. For them, a tablet may sit on a shelf and get little if any use.

Others, however, find the technology fascinating. If you want to see an example that went viral on YouTube, watch this video from 2010 of Virginia Campbell, then 99 years old, and today still going strong at the Mary’s Woods Retirement Community in Lake Oswego, Ore.

Ms. Campbell’s glaucoma made it difficult for her to read, and for her the iPad was a blessing, as she wrote in this tribute quoted in an article in The Oregonian newspaper:

To this technology-ninny it’s clear
In my compromised 100th year,
That to read and to write
Are again within sight
Of this Apple iPad pioneer

Caregivers might be delighted — as Ms. Campbell’s daughter was — by older relatives’ response to this new technology, a potential source of entertainment and engagement for those who can negotiate its demands. Or, they might find that old habits die hard and that their relatives continue to prefer a book or newspaper they can hold in their hands to one that appears on a screen.
