Retinal detachment
Quick answer
Retinal detachment occurs when the retina separates from the layer of tissue that nourishes it at the back of the eye, disrupting its function and putting vision at permanent risk if not treated in time. This is a true eye emergency.
Retinal detachment occurs when the retina separates from the layer of tissue that nourishes it at the back of the eye, disrupting its function and putting vision at permanent risk if not treated in time.
It can be caused by a retinal tear that allows fluid to seep beneath the retina, by traction from the vitreous gel pulling on the retina, or as a complication of other conditions, such as advanced diabetic retinopathy.
Treatment depends on the type and extent of the detachment: it may require laser to seal a tear before it progresses, or surgery — vitrectomy — to reposition the retina once detachment has already occurred.
