We evaluated the incidence of proliferative vitreoretinopathy in rhegmatogenous retinal detachment in 96 eyes with familial exudative vitreoretinopathy (FEVR). Prior to surgery, PVR was present in 15 out of 96 eyes, 16%. After surgery, PVR developed in 13 eyes out of 81 eyes, 13%. These 81 eyes were classified into 2 groups acord-ing to the presence of avascular zone neovascular-ization in the periphery. In 76 eyes assigned to avascular group, PVR developed in 10 eyes, 13%. In 5 eyes assigned neovascular group, PVR developed in 3 eyes, 60%.

The incidence of PVR after surgery was thus greater in neovascular than in avascular group. In all the 81 eyes, the incidence of PVR increased when two or more surgeries were performed. The incidence of PVR was greater in eyes with intraoperative complications including choroidal and subretinal hemorrhages. PVR also developed in 3 out of 7 eyes, 43%, which were treated by intravitreal injecion of fluorosulfide gas, SF6.
