The retina is the light sensitive tissue at the back of the eye that captures the light before sending the visual message to the brain. This part of the eye can become detached (retinal detachment) resulting in loss of vision.
Fortunately, there are several highly successful operations to repair retinal detachments (performed by specialist vitreo-retinal surgeons). The retina is subject to many other conditions many of which can be managed surgically. Some of these include macular holes, epiretinal membranes (macular pucker), advanced diabetic retinal disease, vitreous haemorrhage, and persistently troublesome vitreous floaters.
