Proliferative diabetic retinopathy is the main cause of vision loss in young and middle-aged adults. The central area of the retina is the ‘macula’, shown by the dotted black ring. or Ilyea) needs to be administered directly into the vitreous cavity of the eye in order for it to reach high enough concentrations in the retina to block the dangerous VEGF. As DR worsens over time, fragile abnormal blood vessels develop in the retina at the back of the eye and can leak blood into the central vitreous gel of the eye, obscuring vision. Diabetics are at risk of a variety of health conditions associated with the disease. Diabetic retinopathy is the most common diabetic eye complication and a leading cause of blindness in American adults. In the treatment of diabetic retinopathy somatostatin receptors are the targets of somatostatin analogues like octreotide.
As the disease progresses, new blood vessels grow along the retina and in the vitreous gel of the eye. He should perform an examination of the posterior retina with the direct ophthalmoscope on each diabetic patient at each visit, and should institute prompt referral to an ophthalmologist at the first sign of change. A dilated eye examination allows your doctor to look at the back of the eye and check your retina for early signs of the disease, such as: changes in blood vessels; retinal swelling, such as macular edema; pale, fatty deposits on the retina; or damaged nerve tissue. This monitoring is performed annually for diabetics who have never had any sign of retinopathy, and is more frequent for those with signs of retinopathy, based on the severity of their disease. Dye is injected into your arm. Pictures are then taken as the dye passes through the blood vessels in the retina. This test allows your doctor to locate the leaking blood vessels.
There are two common treatments which are very effective in reducing vision loss from this disease. If the vitreous hemorrhage does not clear within a reasonable time, or if a retinal detachment is detected, an operation called a vitrectomy can be performed. It is important to note that although treatment is very successful, there is no cure for diabetic retinopathy. A few diabetic retinopathy patients – including some who have had photocoagulation – go blind from massive bleeding inside the eye. Early detection and treatment is critical to ocular health, but good management of diabetes is the best prevention. Researchers have found that diabetic patients who are able to maintain appropriate blood sugar levels have fewer eye problems than those with poor control. Diet and exercise also play important roles in the overall health of those with diabetes.
