Information About Diabetic RetinopathyDiabetic Retinopathy is an eye disease that affects people who have diabetes. Because people who suffer from diabetes may often have unstable glucose levels they are prone to circulation problems in the back of the eye known as the Retina. Often diabetics experience a restriction of the flow of blood through the vessels in the Retina, which can cause ischemia, swelling and hemorrhaging. If a hemorrhage occurs when blood vessels break it can sometimes lead to blood in the vitreous gel of one’s eye that then can distort vision and cause the Retina to detach. Without treatment one can face the threat of blindness. For some the blood which accumulates in the eye disappears but for others it will float and or collect causing massive vision blockage. Aside from the threat of blood, sometimes fluid can collect under the Retina-this problem is known as Macular Edema. The proper diagnosis of Diabetic Retinopathy is made during a routine eye examination by directly observing the Retina through a dilate pupil but often requires further testing with Flourescein Angiography and Ocular Coherence Tomography (OCT). Diabetic retinopathy can be found during routine eye exams. Primary care doctors and those taking care of diabetic patients know to pay specific attention to the Retina to make sure no changes are occurring. If changes are found there are three useful treatments depending on the nature and severity of the Diabetic Retinopathy. These include: Laser Treatment, Therapeutic Injections of Triamcinolone Acetinomide (Kenalog), Avastin, and Lucentis, and if a hemmorhage has occured into the eye, Vitrectomy or sugical removal of the Vitreous. Laser Treatment for Diabetic Retinopathy There are two types of laser treatment. The first is known as Panretinal Photocoagulation (PRP) and it consists of laser spots being burned into a wide area across the the Retina tissue to help with the decrease the Retina’s need for oxygen. For this surgery the patient’s eyes are dilated and numbed. The doctor than focuses the laser on the appropriate locations of the Retina and places the laser spots. Sometimes the outter vision of one’s eye is destroyed but the treatment helps save the crucial part center part of one’s vision. The patient will experience light flashes. Since a laser is used the patient will experience some discomfort but healing time is quick although a driver for the trip home is required. The second type of Laser Treatment for Diabetic Retinopathy is known as Focal Laser Photocoagulation. During this procedure the blood vessels of the eye are sealed and shrunken. This procedure feels the same as the first laser treatment, and the patient is given mild numbing drops. This is performed in earlier stages of Diabetic Retinopathy in order to eliminate leaky blood vessels. Vitrectomy Vitrectomy is necessary when there is a hemmorhage from the Retina into the vitreous. During Vitrectomy the patient is mildy sedated and a small incision is made into the white of ones eye allowing a cutting and suction instrument to be used to remove the clouding. For anyone suffering from diabetes, the key to maintaining good vision is to have regular thorough eye examinations. For those who have been diabetic for a number of years, it is often useful to seek out a diabetic eye examination with an eye physician and surgeon who can offer the full range of diagnostic testing and treatment options. |
