Annual Eye Exams Are Lacking Among
Diabetics, and Here's Why
November 2013 Why don't adults with diabetes seek the annual eye care they need?
Researchers from the U.S. Centers for Disease Control and Prevention in Atlanta used data from the multi-state 2006 to 2010 Behavioral Risk Factor Surveillance System to identify respondents who had not sought eye care in the previous 12 months.
The researchers found that, among adults diagnosed with diabetes, 23.5 percent neglected to have recommended annual eye examinations.
"No need" and "cost or lack of insurance" were the most commonly reported reasons for not receiving eye care in the preceding 12 months, according to the study report published in Diabetes Care.
Diabetes Increases Dry Eye Risk
July 2013 If you have diabetes, you are at greater risk for dry eyes, according to a new study.
Researchers in China analyzed previously published studies that evaluated the tears of adults with and without diabetes. Those with diabetes had significantly lower scores for both tear film stability and tear secretion and also had lower corneal sensitivity than those without diabetes.
The study authors concluded that people with diabetes have reduced tear functions and are at higher risk of dry eyes.

Also, patients with proliferative diabetic retinopathy (PDR) a serious complication of diabetes that causes damage to blood vessels in the retina and can lead to blindness are at even greater risk of impaired tear functions, they said.
A full report of the study was published online by the journal Acta Ophthalmologica in June.
Moving to Adulthood Increases Eye and Systemic
Health Risks for Type 1 Diabetics
March 2013 Young people with Type 1 diabetes tend to move from pediatric care to adult care at age 20 to 21, and when this happens, the amount of control over their diabetes tends to drop, says a study by UCLA researchers.
He may be ready for college,
but is he ready to take control
of his Type 1 diabetes?
A seeming result is that they are 2.5 times more likely to have chronically high blood glucose levels, which in turn puts them at higher risk for vision loss from eye diseases such as diabetic retinopathy, heart attacks, strokes and kidney failure later in life.
In Type 1 diabetes (sometimes called juvenile diabetes), the body doesn't produce insulin and can't convert sugar and starches into energy.
It is usually diagnosed in childhood or adolescence, and poor control over the condition when the child leaves home to begin college or work can sometimes be an issue.
In the UCLA study, the type of insurance held made no difference, but when patients were older, had lower baseline blood-glucose levels or had parents with lower education levels, they were more successful in moving to adult care.
A report of the study appeared in the April issue of Pediatrics.
Prevent Dangerous Falls with These Eye Health Tips
September 2012 National Falls Prevention Awareness Day is Saturday, Sept. 22, and it's a great time to do what you can to help elderly friends and family members stay safe from fall-related injury.
Install grab bars in bathtubs and near toilets. They can save lives among people with poor vision.
Start with good eye health, says Prevent Blindness America, because people with poor vision are more likely to have falls.
Diabetics should have annual eye exams to reduce the risk of vision loss associated with fluctuating blood sugar. And people with cataracts shouldn't delay their removal.
In fact, a recent study of Medicare beneficiaries found that those who underwent cataract removal had less risk of hip fracture one year later than those who did not have the cataract surgery during that time. (Read more about it in Cataract News.)
The Centers for Disease Control and Prevention recommends taking these safety measures at home:
- Remove clutter such as shoes from stairs and walkways.
- Remove small rugs or secure them with double-sided tape.
- Make sure all commonly used items are in cabinets that are easily accessible without need for a step stool.
- Install grab bars and non-slip mats in the bathroom.
- Improve the lighting all over the house.
- Make sure staircases are well-lit and have good handrails.
- Always wear shoes, both indoors and out. Avoid going barefoot or wearing slippers.
Some Long-Term Diabetics May Be Protected From Diabetic Eye Disease
PHILADELPHIA, June 2012 It has long been known that diabetes can lead to vision problems. Basically, high glucose levels in the blood damage the eye's blood vessels, leading to sight-stealing diabetic retinopathy.
In fact, nearly 90 percent of people who have had type 1 diabetes for at least 20 years develop diabetic retinopathy, according to Juvenile Diabetes Research Foundation (JDRF).
But some type 1 diabetics seem to avoid serious eye problems. Why is that?
In a study of 158 people who have had type 1 diabetes for 50 years or more, a high proportion had little to no diabetic eye disease over time, and researchers theorize that biological or genetic protective factors may be the reason. They believe that pinning down these factors may help other diabetics avoid such eye diseases or have milder forms of them.
Joslin Diabetes Center conducted the research, which was supported by JDRF. The study results were presented at the 72nd American Diabetes Association's (ADA) Scientific Sessions in Philadelphia this month.
Diabetic Vision Formula: Antioxidant Boost for People With Diabetes
COLUMBUS, Ohio, March 2012 A new eye vitamin for people with diabetes contains carotenoid antioxidants designed to counteract the oxidative stress that can affect the eye's blood vessels.
This is thought to cause vision problems associated with diabetic retinopathy.
Manufacturer EyeScience says Diabetic Vision Formula is designed to complement an existing vitamin regimen, but adds that it is best to check with your physician and eye doctor to make sure all your supplements and medications are compatible with each other.
Is Diabetic Retinopathy Declining...or Increasing?
ATLANTA, January 2012 According to data recently published by the U.S. Centers for Disease Control and Prevention (CDC), the percentage of people with diabetes who have vision problems from the disease has declined significantly in the past 14 years.*
But the news might not be as good as it sounds.
Though the CDC found that the age-adjusted percentage of adults in the U.S. with diagnosed diabetes who reported visual impairment declined from 23.7 percent in 1997 to 16.7 percent in 2010, the number of adults with vision problems from diabetes actually increased during this time frame.
The data showed that 3.9 million Americans reported having diabetes-related vision problems in 2010, up from 2.7 million in 1997 an increase of 44 percent. The reason for this increase is the significant increase in new cases of diabetes in the United States over the past decade.
According to the United Health Foundation, diabetes affected 8.7 percent of the U.S. population in 2011 a 42.6 percent increase since 2001.**
The declining trend in self-reported vision impairment from diabetic retinopathy and other diabetic eye disease may be due to the large number of persons who have not had diabetes long enough to develop vision problems. With time, the encouraging trend in self-reported vision impairment prevalence from diabetes might reverse, the researchers warned.
The researchers also said that too many people with diabetes-related vision problems aren't getting the vision care they need. The study found that only about 63 percent of the study respondents with diabetes and vision impairment visited an eye doctor for the annual dilated eye exam that is recommended for people with diabetes.
According to the CDC, nearly 26 million people in the United States had diabetes in 2010, and 79 million adults were at high risk for developing type 2 diabetes. However, people with diabetes can take steps to control the disease and lower their risk for complications, and those at high risk for diabetes can prevent or delay the onset of type 2 diabetes with weight loss and physical activity, the researchers said.
