Retinal ischemia can be regarded as possible aftereffect of central retinal vein occlusion (CRVO). Ischemia means a tissue having reduced blood supply to an insufficient level. Lack of oxygen in the retinal tissue may lead to retinal cell death or cell dysfunction, and thereby, result in reduced vision. It is a common cause of visual impairment and loss of vision. The causes of retinal ischemia may be: vein and artery occlusions, diabetes and macular degeneration and more. Symptoms depend on what the ischemia is related for. Like if it is in the intestines then there may be pain in their abdomen whereas if the ischemia is related to blockage in the arteries in the legs, it could cause pain in the foot/leg.
Retinal ischemia affects the peripheral retina, so there may not be the presence of many visual symptoms, or a wedge out of peripheral vision may be noticed. When retinal ischemia is present in the mid and center area of the retina, a significant decrease in your vision may be noticed. Treatment for retinal ischemia depends on the cause, however, the injections of medication into the eye give some relaxation that helps to reduce swelling, and cause regression of abnormal blood vessels. A healthy lifestyle and regular medical checkups lifestyle will help to reduce further complication if any.
