Retinopathy

The non-inflammatory degenerative disease of the retina. Central serous retinopathy a usually self-limiting condition marked by acute localized detachment of the neural retina or retinal pigment epithelium in the region of the macula, with hypermetropia. Circinate Retinopathy a condition marked by a circle of white spots enclosing the macular area,   leading to complete foveal blindness. Diabetic Retinopathy retinal manifestations of DIABETES MELLITUS, including MICROANEURYSMS and punctate exudates. There are two major forms of diabetic retinopathy, nonproliferative and proliferative. The non-proliferative form is characterized by dilation of the retinal veins and micro aneurysms which may leak blood cells and/or plasma, causing internal hemorrhaging or edema in the retina. Edema in peripheral areas of the retina goes unnoticed by   the patient and may go untreated, whereas edema occurring in the central retina (macula) causes noticeably decreased vision and is the primary cause of vision loss in nonproliferative disease. Treatment by local laser PHOTO-COAGULATION is aimed at sealing shut the breaks in the blood vessels and preventing additional leakage of fluid into the area. Early diagnosis and treatment is essential in this disease to enhance a final visual outcome of stabilization and prevention of further loss of vision.
