A retinal detachment is a condition where fluid accumulates behind the retina, causing it to separate from the eye wall. Common symptoms include a dark shadow or curtain in one eye, which does not improve, and often increases over time. Retinal detachments most commonly arise from a retinal tear, but certain types of retinal detachments can come from diabetes or inflammation. A retinal detachment is a serious condition which can cause complete and irreversible blindness. Retinal detachments almost always require surgical repair in the operating room. The outcome of retinal detachment surgery depends on the nature and duration of the retinal detachment. Any patient who is experiencing symptoms of a retinal detachment should present to the retina clinic emergently for evaluation.
