- = detached retinaseparation of the inner nervous layer of the retina from the outer pigmented layer (retinal pigment epithelium) to which it is attached. It commonly occurs when one or more holes in the retina allow fluid from the vitreous cavity of the eyeball to accumulate under the retina. Vision is lost in the affected part of the retina. The condition can be treated surgically by creating patches of scar tissue between the retina and the choroid by application of extreme cold (see cryosurgery) or heat (see photocoagulation); this, combined with plombage, allows reattachment of the retina.
