Diabetes and Your Eyesight
Posted by Maxene on November 30th, 2007Most people don’t really know a whole lot about diabetes — but the one thing they think they know is the effect diabetes has on your vision. A surprising number of people are convinced that diabetics are destined to become blind — if not now, later.
That may have been true once — long ago, before medical technology had advanced to the point where it is now and people’s understanding of diabetes management evolved to today’s standard. The situation now is different. While people with diabetes do have a statistically higher chance of becoming blind than those without diabetes, many of the conditions that contributed to deteriorating vision or total vision loss can now be effectively managed or minimized.
One of the main vision-related conditions diabetics need to be concerned about is glaucoma. According to the American Diabetes Association, people with diabetes are 40% more likely to have glaucoma than people without diabetes.
What is glaucoma?
Glaucoma is the name of a group of eye diseases that adversely affect vision. In all of the glaucomas, pressure within the eye slowly damages the optic nerve, eventually destroying vision. The most common form of glaucoma is open angle glaucoma, which manifests no symptoms until the vision has already been damaged. There is no cure for open angle glaucoma, but the progression of the disease can be slowed in order to preserve vision.
Because open angle glaucoma has no symptoms — you can’t ‘feel it’ coming on — it is essential for all people, and especially diabetics, to have regular eye exams. These exams must include an optic nerve check and a check of the pressure in the eye, known as tonometry. Many individuals don’t care for the tonometry exam, finding it uncomfortable, but it is a momentary discomfort compared to the ongoing, permanent damage glaucoma can cause if left unchecked.
Other types of glaucoma: acute glaucoma, low-tension, congenital, and secondary glaucoma, are similar in nature to open angle glaucoma. Acute glaucoma is distinct because it usually manifests with severe pain and nausea to the patient.
For the best prognosis, glaucoma should be detected and treated early. Treatment for glaucoma generally begins with a course of eye drops. If the eye drop medication fails to halt the progression of the disease, laser surgery or traditional eye surgery are the recommended course of action. Obviously, each individual responds to the condition differently, and courses of treatment will be different for each patient.
The risk of glaucoma and other vision problems associated with diabetes make it essential for the diabetic to form a strong and lasting relationship with their ophthalmologist. The trained eyes of a medical professional are the best tool you have at your disposal to protect your vision Regular exams, coupled with the careful tracking of changes in your eyes, are the first line of defense against glaucoma. Glaucoma medicines are stronger and more effective than ever before, offering diabetics a wide range of tools to be used to preserve their vision.
