retinal detachment

views updated

retinal detachment (detached retina) n. separation of the inner nervous layer of the retina from the outer pigmented layer (retinal pigment epithelium), causing loss of vision 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 (see cryosurgery, photocoagulation); this, combined with plombage, allows reattachment of the retina.
