Diabetes Degrades Vision

Diabetes Degrades Vision.
Less than half of adults who are losing their phantom to diabetes have been told by a fix that diabetes could damage their eyesight, a new study found. Vision impairment is a common complication of diabetes, and is caused by damage that the chronic disease does to the blood vessels within the eye. The difficult can be successfully treated in nearly all cases, but Johns Hopkins researchers found that many diabetics aren't taking heedfulness of their eyes, and aren't even aware that vision loss is a potential problem. Nearly three of every five diabetics in peril of losing their sight told the Hopkins researchers they couldn't withdraw a doctor describing to them the link between diabetes and vision loss.

The study appeared in the Dec 19, 2013 online version of the journal JAMA Ophthalmology. About half of people with diabetes said they hadn't seen a health-care provider in the one-time year. And two in five hadn't received a squarely eye exam with dilated pupils, the study authors noted. "Many of them were not getting to someone to look over them for eye problems," said study leader Dr Neil Bressler, a professor of ophthalmology at the Johns Hopkins University School of Medicine.

And "That's a humble because in many of these cases you can attend this condition if you catch it in an early enough stage," added Bressler, who is also chief of the retina dividing at the Johns Hopkins Wilmer Eye Institute. One-third of the people said they already had suffered some perspective loss related to their diabetes, according to the report. Bressler said vision damage can be prevented or halted in 90 percent to 95 percent of cases, but only if doctors get to patients soon enough.

Drugs injected into the liking can reduce swelling and lower the risk of vision loss to less than 5 percent. Laser cure has also been used to treat the condition, the researchers said. Dr Robert Ratner, primary scientific and medical officer for the American Diabetes Association, called the findings "frightening" and "depressing. This writing-paper is an excellent example of where the American health care delivery system has fallen down in an neighbourhood where we can clearly do better".

For the study, researchers used survey data collected by the US Centers for Disease Control and Prevention between 2005 and 2008 to judgement the responses of people with genus 2 diabetes who had "diabetic macular edema". This condition occurs when high blood sugar levels associated with sick controlled diabetes cause damage to the small blood vessels in the retina, the light-sensitive pile lining the back wall of the eye. As the vessels leak or shrink, they can cause prominence in the macula - a spot near the retina's center that is responsible for your central vision.
