Complications and management of post-vitrectomy circumferential retinal detachment

Four consecutive patients with chronic peripheral circumferential detachment developed vision-threatening complications requiring further treatment. All four cases had more than one previous vitreoretinal surgery; two cases had silicone oil intravitreally and three had crystalline lens removed. The main complications included chronic hypotony (1 case), rubeosis iridis (4 cases), intraocular hemorrhage (1 case), neovascular glaucoma (1 case), and cataract (1 case). Retinectomy with peripheral traction release and silicone oil infusion resulted in improvement or stabilization of visual function in all four cases.
