Summary

Content: Detached retina
A detached retina is when the retina lifts away from the back of the eye. It can cause total or partial loss of vision in the affected eye. When a person has a detached retina, it may appear that something is blocking part of their vision. A detached retina is serious. If left untreated, it can lead to permanent vision loss. Treatment involves some form of surgery dependent on what a person’s doctor recommends. Black eye
A black eye occurs as a result of an injury to the eye and can affect a person’s vision. “A black eye” is a term that refers to bruising around the eye, usually caused by impact to that area. Increased pressure inside the eyeball can occur from any swelling caused by a black eye. This in turn can lead to vision loss.
