How Diabetes can affect your Vision
Not controlling your blood sugar levels and adhering to a strict diet can cause changes to the blood vessels inside the retina in the back of the eye. Blood vessels may swell or leak, or new abnormal blood vessels can grow that lead to gradual vision loss and eventual complete loss of vision that cannot be regained. This is diabetic retinopathy.
Treatment of Diabetic Retinopathy
The location of the disease and the degree of damage to the retina determines the type of treatment of diabetic retinopathy. There are two effective methods in reducing vision loss from this disease. One method involves treatment with laser photocoagulation, a way of sealing off the leaking blood vessels and causing abnormal blood vessels to regress. A more recent approach involves injecting drugs into the eye that modulate vascular permeability and/or reduce the inflammatory response within the retina.
Diabetic Retinopathy Prevention
The best treatment for diabetic retinopathy is prevention. Early detection and management is important to prevent the development of the more sight damaging stages of the disease. Keeping blood sugar at an even level and frequent eye examinations will help. With careful monitoring, treatment of diabetic retinopathy can be started long before sight is affected.
