What is Diabetic Retinopathy?
Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults. In the majority of diabetic retinopathy cases, blindness is completely preventable. Patients will need to work closely with the Dr. Schnipper to monitor and treat this disease. The use of medications and daily blood sugar monitoring can make a major impact on containing the worsening of diabetic retinopathy.The retina is the like the film in a camera; in which it is the light sensing film on the back of the eye that captures the images. In the diabetes disease, sugar (glucose) builds up within blood vessels in the retina and tissues of the body causing it to attach to the proteins in the wall. This alters the vessel’s normal structure and functioning. The vessels eventually get blocked and leak fluid. When they cannot deliver an adequate amount of blood supply to the eye, the eye can generate abnormal new blood vessels. Early diabetic retinopathy usually has no symptoms. However, worsening diabetic retinopathy can lead to visual loss and blindness.
Stages of Diabetic Retinopathy
The stages of diabetic retinopathy are divided into two categories, nonproliferative retinopathy and proliferative retinopathy.
This is the first and earliest stage of diabetic retinopathy. NPDR occurs when the small blood vessels of the retina start to leak fluid or bleed. This activity will lead to the formation of deposits called exudates. Once these blood vessels start to leak swelling within the central part of the retina occurs. When the leakage of these blood vessels causes swelling, macular edema sets in and the blood vessels can become blocked. This stage of diabetic retinopathy is common when a person develops diabetes. Most diabetics have some grade of NPDR. It is imperative to maintain regular eye examinations with the retina specialists at Inland Eye Specialists to monitor and treat NPDR.
When new vessels start to grow as a result of the existing vessels becoming blocked, this marks the beginning of the next stage of diabetic retinopathy, proliferative diabetic retinopathy. This level of diabetic retinopathy is the most severe and dangerous for the diabetic patient. These new abnormal blood vessels can grow on the retina, optic nerve, iris or into the vitreous gel inside the eye, and tend to grow poorly and are very fragile. The damage that these blood vessels bring to retina can be catastrophic and include hemorrhages on the retina, scar tissues build up, and possible retina detachment.
Diabetic Retinopathy Symptoms
Diabetic retinopathy does not really have any initial warning signs. Dr. Schnipper suggests that all diabetic patients have regular eye examinations to monitor your eyes for changes.
- Retinal swelling may cause blurred vision and distortion.
- Objects may look smaller or larger than normal
- Floaters may appear due to the bleeding of the blood vessels.
If proliferative diabetic retinopathy is left untreated blindness can occur. The best alternative to fighting PDR is early detection. It is important for diabetics to have regular eye exams to watch for PDR.
