Central Retinal Vein Occlusion and Branch Retinal Vein Occlusion
Prognosis
Most patients have some visual deficit. In mild cases, there can be spontaneous improvement to near-normal vision over a variable period of time. Visual acuity at presentation is a good indicator of final vision. If visual acuity is at least 20/40, visual acuity will likely remain good, occasionally near normal. If visual acuity is worse than 20/200, it will remain at that level or worsen in 80% of patients. Central retinal vein occlusions rarely recur.
