A smaller branch of the main retinal vein is blocked. Only the part of the retina drained by this branch vein is damaged. Blurred vision is the main symptom of retinal vein occlusion. It occurs when the excess fluid leaking from the vein collects in the macula. The macula is the central area of the retina which is responsible for our central, detailed vision.
Floaters can appear as spots which interfere with vision.
They can bleed or leak fluid into the vitreous, the gel-like fluid that fills the center of the eye, causing the floaters. It is caused by excessive eye pressure called neovascular glaucoma. Your ophthalmologist may also suggest a visit to your family physician to discover and manage any associated medical problems. There is no cure for retinal vein occlusion. Your ophthalmologist may recommend a period of observation, since hemorrhages and excess fluid may subside on their own Laser surgery improves sight in some patients with macular edema, but vision does not usually return entirely to normal.
