Diabetes degrades vision

Diabetes degrades vision.
Less than half of adults who are losing their mirage to diabetes have been told by a practise medicine that diabetes could damage their eyesight, a new study found. Vision reduction is a common complication of diabetes, and is caused by damage that the chronic disease does to the blood vessels within the eye. The refractory can be successfully treated in nearly all cases, but Johns Hopkins researchers found that many diabetics aren't taking sorrow of their eyes, and aren't even aware that vision loss is a potential problem penis masuk d vagina. Nearly three of every five diabetics in hazard of losing their sight told the Hopkins researchers they couldn't remembering a doctor describing to them the link between diabetes and vision loss.

The study appeared in the Dec 19, 2013 online stream of the journal JAMA Ophthalmology. About half of people with diabetes said they hadn't seen a health-care provider in the above-named year. And two in five hadn't received a busty eye exam with dilated pupils, the study authors noted kerala. "Many of them were not getting to someone to enquire into 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 handle this condition if you catch it in an early enough stage," added Bressler, who is also chief of the retina sector at the Johns Hopkins Wilmer Eye Institute. One-third of the people said they already had suffered some spectre 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 with dispatch enough.

Drugs injected into the perception 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, essential scientific and medical officer for the American Diabetes Association, called the findings "frightening" and "depressing. This report is an excellent example of where the American health care delivery system has fallen down in an precinct 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 analysis the responses of people with group 2 diabetes who had "diabetic macular edema". This condition occurs when high blood sugar levels associated with indisposed controlled diabetes cause damage to the small blood vessels in the retina, the light-sensitive combination lining the back wall of the eye. As the vessels leak or shrink, they can cause enlargement in the macula - a spot near the retina's center that is responsible for your central vision.

Treat Glaucoma Before It Is Too Late

Treat Glaucoma Before It Is Too Late.
Alan Leighton discovered he had glaucoma when he noticed a gray yard of discern in his left eye. That was in 1992. "I over I had it a long time before that, but I didn't know until then," said Leighton, 68, a corporate treasurer who lives in Indianapolis. "Glaucoma is groove on that. It's sneaky".

Leighton made an nomination with his ophthalmologist to see what was wrong. "We went for a bunch of tests, and he ascertained there was an issue with that eye, and that I had normal pressure glaucoma".

His response was unsentimental and pragmatic: His subdivision has a history of glaucoma, so the news wasn't a total surprise. "I stony that we needed to take the most proactive methods we could. I would go to the best people I could find and woo what methods they had to address it and keep it from getting worse. I wanted to keep it from affecting my right eye, which was somewhat clear. I didn't know what the process was going to be to actually stop the glaucoma or trouble it, if it was even possible. I don't know if there was a lot of emotion involved. It was more like, 'Hey, what can we do about this?'".

He asked if there was any fashion to restore the sight he'd lost, and the answer was no. "They unbelievably much said that gray area in my left eye was going to stay there, and there was no occasion to do any procedures to effectively change that. It had something to do with the optic nerve".

Glaucoma Is Attacking The US Population

Glaucoma Is Attacking The US Population.
The changing makeup of the US populace is expected to actress to an increase in cases of glaucoma, the leading cause of vision ruin in the country, experts say. A number of demographic and health trends have increased the numeral of Americans who fall into the major risk groups for glaucoma. These trends include: the aging of America, increase in the black and Hispanic populations, the ongoing obesity epidemic.

And as more people become at risk, steady eye exams become increasingly important, eye experts say. Early detection of glaucoma is leading to preserving a person's sight, but eye exams are the only way to catch the complaint before serious damage is done to vision. "The big thing about glaucoma is that it doesn't have any signs or symptoms," said Dr Mildred Olivier of the Midwest Glaucoma Center in Hoffman Estates, Ill, and a embark on fellow of Prevent Blindness America.

And "By the time someone says, 'Gosh, I have a problem,' they are in the end stages of glaucoma," Olivier said. "It's already captivated most of their sight away. That's why we title glaucoma 'the sneak thief of sight.'"

Glaucoma currently affects more than 4 million Americans, although only half have been diagnosed, according to the Glaucoma Research Foundation. It's cited as the cause of 9 to 12 percent of all cases of blindness in the United States, with about 120000 forebears blinded by the disease.

Glaucoma is most often caused by an broaden in the routine fluid pressure inside the eye, according to the US National Eye Institute. The added lean on damages the optic nerve, the bundle of more than a million nerve fibers that shoot signals from the eye to the brain. In most cases, people first notice that they have glaucoma when they begin to mislay their peripheral vision.

By then, it's too late to save much of their eyesight. "Glaucoma is the calculate one cause of irreversible but avoidable blindness," said Dr Louis B Cantor, chairman and professor of ophthalmology at the Indiana University School of Medicine and foreman of the glaucoma service at the Eugene and Marilyn Glick Eye Institute in Indianapolis. "By the fix it's noticeable, 70 to 90 percent of dream has been lost," he said. "Once it's gone, it's gone. There's no retrieving scheme lost to glaucoma".

The most common risk factor for glaucoma is simply surviving. "Glaucoma is a c murrain of aging," Cantor said. "The risk of developing glaucoma goes up considerably with aging". As the natives of the United States ages, the number of glaucoma cases will logically increase. As Olivier said, "We're just going to have more people who are older and living longer, so we'll have more glaucoma".
