If you think of Type 1 and Type 2 Diabetes it is only natural to think of high blood sugar . But do you know why persistent high blood sugar is a problem in the first place?
It turns out that the effects of diabetes-induced blood sugar can damage many physiological systems, including the eyes a phenomenon known as diabetic eye disease. What you need to know about it and how you can reduce the likelihood that it will happen to you.
Diabetic eye disease is an umbrella term used to describe various eye diseases.
A key condition in this group is diabetic retinopathy, the leading cause of vision loss among diabetics, according to the National Eye Institute (19459016) (NEI). It happens when persistently high blood sugar damages blood vessels in the retina, the thin piece of tissue in the fundus that processes light.
Then there is the related disease diabetic macular edema (DME), a consequence of diabetic retinopathy causing fluid buildup in part of the retina, the macula, NEI . The macula is responsible for the direct view used to read, drive and see faces. According to NEI about half of people with diabetic retinopathy will develop DME.
Both diabetic retinopathy and DME can cause severe vision problems or even persistent blindness, which says NEI ]. (Diabetic eye disease also includes cataracts or opacification of the lens and glaucoma, a group of diseases that damage the optic nerve.) We will focus on diabetic retinopathy and DME because the former is so common and the latter is often a related consequence .)
The early symptoms of diabetic retinopathy and DME are vague to nonexistent.
In the early stages of diabetic retinopathy, people usually have no symptoms, explains the NEI . Long-term bleeding from damaged retinal blood vessels can lead to floating spots in a person's vision that may not clear and then reappear. If someone also has DME due to diabetic retinopathy, he may experience blurred vision [Floatern] . Eventually, this can lead to vision loss or permanent blindness.
Because these conditions cause little to no symptoms, a regular eye exam in diabetes, Colin A. McCannel, a professor of ophthalmology and medical director, is essential to the UCLA Stone Eye Center in Santa Monica, says SELF. The early capture and treatment of diabetic retinopathy reduces the risk of blindness by 95 percent, according to NEI . For the best chance, you should consult your ophthalmologist at least once a year for a comprehensive eye exam including dilatation.
The treatment of diabetic retinopathy and DME varies according to the problem and severity of your medical team finding it.
If you have had diabetic retinopathy soon enough, it may Mayo Clinic .
for the time being be sufficient to get your blood sugar under control. Even if diabetic retinopathy has it After the transition to DME, it is sometimes possible to stop or even reverse the resulting vision loss, says Jeffrey Walline, OD, Ph.D., deputy dean of research at Ohio State University College of Optometry, versus SELF. Treatments that improve vision problems caused by diabetic retinopathy and DME include injections of drugs into the eyes to stop the growth of leaking blood vessels, corticosteroids to reduce ophthalmia, and laser surgery to reduce blood vessel leakage and swelling. NEI says. But sometimes, this loss of vision is irreversible, so early detection and treatment is crucial.
If you have diabetes and have recently had vision problems, consult your ophthalmologist, ASAP.
This is a good rule Even if you do not believe you have diabetes, Mina Massaro-Giordano, co-director of the Penn Dry Eye & Ocular Surface Center and a professor of ophthalmology at the University of Pennsylvania, told SELF ,
Beyond that, even if you are symptom free, these eye visits (19459044) make at least once a year – and hold – says Dr. McCannel. This is crucial for the overall health of your eyes, especially if you have diabetes.
