retinal detachment

Full Definition

Retinal detachment is a serious condition where the neurosensory retina becomes separated from the retinal pigment epithelium (RPE), disrupting the normal metabolic relationship between these layers. There are three main types: rhegmatogenous (caused by a retinal tear), tractional (caused by fibrovascular proliferation), and exudative (caused by fluid accumulation without a tear). This condition constitutes an ophthalmic emergency requiring prompt surgical intervention to prevent permanent vision loss.

Usage

Usage note: Always specify the type (rhegmatogenous, tractional, or exudative) and whether the macula is involved.
