Rhegmatogenous retinal detachment (RRD)
Color retinography (CLARUS 500, Zeiss): lower retinal detachment involving the macula. There is a small subretinal proliferation next to the inferior temporal vascular arcade.
(A): Lifting of the neurosensory retina with the characteristic undulations of the outer retina
(B): Intraretinal fold
Description
The word “rhegmatogenous” comes from the Greek word rhegma , meaning break. RRDs are caused by the passage of fluid from the vitreous cavity into the potential space between the neurosensory retina and the retinal pigment epithelium through a retinal tear or hole. A spontaneous RRD is usually preceded by a posterior vitreous detachment. The case presented is accompanied by preretinal vitreoretinal proliferation, a scarring process that begins at the time of detachment with the intention of trying to close the retinal tears. This generates contraction and folds in the retina, which can produce new holes.
