Abstract
• One thousand eighty-eight consecutive operations for retinal detachment were analyzed to determine the influence of current methods of examination and treatment on failures following surgery. The majority of failures were produced by preretinal membrane formation (33%) and massive preretinal retraction (27%). Other causes of failure included undetected retinal breaks (13%), inadequate scleral buckle (10%), new retinal breaks (8%), inadequate chorioretinal reaction (7%), and iatrogenic retinal breaks (2%). Primary operations yielded an initial cure rate of 76%. Successful reoperations raised the final cure rate to 89%. Reoperations were associated more frequently with preretinal membrane formation and had a lower final cure rate (83%). This study emphasizes the importance of recognition and management of preretinal membrane formation. Except for new retinal tears and massive preretinal retraction, surgical failures can be avoided by improved utilization of current examination and operative techniques.
