Detached retina

A condition in which the retina becomes partially separated from the eyeball, causing loss of vision.


Separation of the retina from the choroid in the back of the eye, usually resulting from internal changes in the eye, sometimes from severe injury. Symptoms include the sensation of flashing lights as the eye is moved, the appearance of floating spots in front of the eye, and loss of vision in the affected part of the retina. Treatment is by surgery. Also called retinal detachment.


Separation of the retina from the layer of the eyeball (choroid) to which it is attached. It commonly occurs when one or more holes in the retina allow vitreous fluid from the cavity of the eyeball to accumulate between the retina and choroid, which are only delicately attached. Sometimes the detachment is secondary to inflammation or tumor of the choroid or disorder of the vitreous humor. Vision is lost in the affected part of the retina. The condition can be treated surgically by creating patches of scar tissue on the retina (by application of extreme heat or cold; see photocoagulation), which stick it back into place.


Separation of the retina from the choroid in the eye. It may be due to trauma or be secondary to tumour or inflammation of the choroid, and causes blindness in the affected part of the retina. It can be treated surgically using photocoagulation.
