Why do Diabetics Skip Eye Exams

Diabetics Skip Eye Exams

Originally posted at webmd.com (HealthDay News) — Almost two-thirds of people with diabetes don’t get annual eye exams, despite having an increased risk for serious eye disease and vision loss, researchers say.

About one in 10 Americans has diabetes. Having a dilated eye examyearly or more often can prevent 95 percent of diabetes-related vision loss, the study authors said.

“Vision loss is tragic, especially when it is preventable,” study lead author Dr. Ann Murchison said in a news release from the American Academy of Ophthalmology (AAO).

“That’s why we want to raise awareness and ensure people with diabetes understand the importance of regular eye exams,” said Murchison. She is director of the eye emergency department at Wills Eye Hospital in Philadelphia.

 The study included information from nearly 2,000 people aged 40 and older with type 1 or type 2 diabetes. The researchers found that 58 percent didn’t have regular follow-up eye exams.

Smokers were 20 percent less likely to have regular eye exams. People with less-severe disease and no eye problems were the least likely to get their eyes checked each year, according to the report.

Patients with diabetic retinopathy were 30 percent more likely to have regular eye exams, the study authors said. Diabetic retinopathy involves changes to blood vessels in the retina that can cause them to bleed or leak fluid, distorting vision. It’s the most common cause of vision loss among people with diabetes and a leading cause of blindness among working-age adults.

“People with diabetes need to know that they shouldn’t wait until they experience problems to get these exams,” said Dr. Rahul Khurana, an AAO clinical spokesperson. “Getting your eyes checked by an ophthalmologist can reveal the signs of disease that patients aren’t aware of.”

November is Diabetic Eye Disease Awareness Month.

The study findings were presented recently at the annual meeting of the American Academy of Ophthalmology, in Chicago. Findings presented at meetings are generally viewed as preliminary until they’ve been published in a peer-reviewed journal.

Diabetics blinded by the disease have been offered new hope afters scientists unveiled the first new treatment in 40 years.

Researchers said that injections of the drug ranibizumab improved sight when compared to traditional treatments for people with proliferative diabetic retinopathy (PDR).

The disorder occurs when high blood sugar levels damage the cells at the back of the eye. If it isn’t treated, it can cause blindness.

PDR is a leading cause of vision loss in patients with diabetes and the standard treatment has been laser surgery which can result in loss of peripheral vision and difficult seeing at night.

However the new treatment allowed patients to keep their peripheral vision while improving central sight so they could see eye charts more accurately and read half a line more, on average.

“This important study represents a major step forward for patients with PDR by providing the ophthalmologists who manage their retinal disease with new options,” said Dr Timothy Olsen, of Emory University, Atlanta.

The injections would need to take place once a month for three months.

The number of adults with diabetes has risen more than 65 per cent since 2005, with more people than ever at risk of blindness.

Diabetes is the leading cause of blindness in people of working age in the UK. It is estimated that there are 4,200 people in England who are blind due to diabetic retinopathy.

Within 20 years of diagnosis nearly all people with Type 1 and almost two thirds of people with Type 2 diabetes (60 per cent) have some degree of eye disorder.

Almost 3.5 million people in the UK are now living with diabetes, according to new analysis of GP data for the British Heart Foundation (BHF).

In the last year alone, there has been a 3.5 per cent rise in cases, while hundreds of thousands more people are undiagnosed with Type 2 diabetes, which is linked to obesity and unhealthy lifestyles.

To mark World Diabetes Day, the charity is announcing more than £3 million of funding for research into the link between heart disease and diabetes, plus new treatments for the condition.

Professor Peter Weissberg, medical director of the BHF, said: “Diabetes is a major risk factor for cardiovascular disease. Up to four million adults in the UK have diabetes so treatments are urgently needed that can help prevent them suffering a deadly or disabling heart attack or stroke.

“Research we’re funding is showing us how diabetes can affect the blood vessels and bring on disease. By understanding this process, we hope to develop medicines that can prevent this disease process or even reverse it.”

The new research was presented at the American Academy of Ophthalmology annual meeting and published in the journal JAMA.

Diabeties is a leading cause of blindness in American adults. Partially because it is often missed until it is too late. Now, a new treatment is helping save patients’ sight.

Sixty-eight year old Charles Cavill was in danger of losing his sight, but now, for the first time in years, he can play golf again. Cavill told Ivanhoe, “When you can’t make good contact with the ball because your vision’s not there, you learn not to play.”

Like many Americans with diabetes, the tiny blood vessels in Cavill’s eyes became damaged and the retinas swelled. He underwent laser surgery and cataract surgery in both eyes but he still needs injections of a steroid to control the swelling. Before Iluvien, the injections were administered monthly. But now, one injection is good for three years.

FDA-approved, Iluvien came on the market in March. It can be administered during an office visit, it’s long-lasting, and doctors say it is low risk even for patients with glaucoma and cataracts.

Ophthalmologist Robert Wang, MD, said, “One of the great things about this drug, it’s absolutely going to reduce the leading cause of blindness from diabetic macular edema in the United States.”

For Cavill, Iluvien has improved the quality of his life. He said, “I don’t have to get another injection for three years. That’s pretty amazing.” That means less time at the doctors and more time on the links.

Doctors say the best way to prevent blindness associated with diabetes is to keep your sugar under control and get regular eye exams.


New Eye Monitoring Device Spots Early Signs of Diabetes

diabetic autonomic neuropathy New Eye Monitoring Device Spots Early Signs of DiabetesAutonomic neuropathy is a common complication arising from diabetes, causing side effects like gastroparesis, erectile dysfunction, and other conditions due to damaged autonomic nerves. Early detection of diabetic autonomic neuropathy can have substantial benefits to patients thanks to treatment commencing sooner than it does now. Now researchers at National Taiwan University Hospital and National Chiao-Tung University in Taiwan developed an optical sensor that hangs off a pair of glasses and helps spot autonomic neuropathy by monitoring the activity of the eye for a half hour.

diabetic neuropathy detector New Eye Monitoring Device Spots Early Signs of DiabetesThe device shines light from four color LEDs into the eye in order to stimulate the pupil to change size. It does this repeatedly, changing certain parameters, while a camera watches the pupil dilate in response to the light. By measuring the size of the pupil, its response time, and response speed, the researchers have shown that the new pupillometer may be a new modality for spotting autonomic neuropathy much earlier than what doctors are currently able to do. There are more extensive clinical trials planned to confirm the efficacy of the technology, with the hope that in a few years we’ll have convenient glasses that a patient can wear during a regular checkup to check for early signs of diabetes.

From the Optical Society:

Currently doctors rely on observing changes in digestive speed, heart rate and blood pressure to detect diabetic autonomic neuropathy, but this limits their ability to make a diagnosis early on, said Mang Ou-Yang, who led the research with colleagues at National Chiao-Tung University. Now they have shown that monitoring the pupils of people with diabetes may be a better approach.

“Compared to the existing diagnostic techniques, the pupillometer is a more reliable, effective, portable and inexpensive solution for diagnosing diabetic autonomic neuropathy in its early stages,” said Ou-Yang.

The pupil is useful for detecting diabetic autonomic neuropathy due to the neurological conditions caused by the disease. Like many organs, the eyes and pupil are dually innervated, receiving signals from both the parasympathetic and sympathetic divisions of the autonomic nervous system. These divisions control the pupil’s circular and radial muscles, respectively.
