detachment of the retina


Also found in: Dictionary, Thesaurus, Wikipedia.

detachment of the retina

A separation of the neural layer of the RETINA from the underlying pigment layer as a result of a collection of fluid between the two. This is usually preceded by the development of retinal holes or tears, but detachment may be associated with traction by contracting strands of VITREOUS HUMOUR. Detachment tends to be progressive and separation of the MACULA LUTEA usually results in loss of visual acuity even if the retina is replaced.
