Retinopathy of Prematurity Stage 4 Subtotal Retinal Detachment
Definition 1
An ophthalmoscopic finding that refers to retinopathy of prematurity characterized by the presence of subtotal retinal detachment. (NCI Thesaurus)
Definition 2
Prior to the development of ROP in the premature infant, vascularization of the retina is incomplete or "immature". In Stage 4: Subtotal Retinal Detachment the retinal detachments are generally concave and most are circumferentially oriented. Retinal detachments usually begin at the point of fibrovascular attachment to the vascularized retina and the extent of detachment depends on the amount of neovascularization present. (NICHD)
