Drainage of subretinal fluid was performed in 84 of a consecutive series of 662 primary scleral buckling procedures, and complications of this maneuver were observed in 5.6 of cases. The ultimate anatomic success rate in this series was 94.2. Although 97 of failures were due to massive proliferative vitreoretinopathy, the process developed in no eyes in which complications of drainage were observed. Drainage of subretinal fluid is a potentially hazardous maneuver, but complications of this procedure are an uncommon cause of anatomic failure in retinal reattachment surgery.
