The part of the eye which collects light and transmits the light messages to the optic nerve and brain is the retina. It lines the inner back wall of the eye. When the retina separates from the back wall, it is known as retinal detachment. It is a serious condition which can cause permanent damage and vision loss if not treated quickly.
Symptoms
A retinal detachment often causes sudden defects in your vision. It may just cause a blind spot too small to notice, or it may cause a noticeable shadow which obscures your vision. An increase in “floaters,” which look like small particles or fine threads, may also be noticed. Finally, flashes of light are associated with retinal detachment.
Risk Factors
Eye injuries, tumors, and cataract surgery can cause retinal detachment. Nearsighted individuals and the elderly are at greater risk for spontaneous detachment. Also, diabetic retinopathy, a condition associated with diabetes, can cause bleeding which leads to retinal detachment.
