Visual results and complications after retinal reattachment in the acute retinal necrosis syndrome. The influence of operative technique.

The authors compare the complications and visual results encountered in a consecutive series of 16 eyes undergoing retinal reattachment surgery for retinal detachment associated with the acute retinal necrosis syndrome. Eight eyes were treated with scleral buckling, vitrectomy, and cryotherapy with or without gas injection. Eight consecutive eyes (with one exception) were treated by the combination of vitrectomy, gas injection and laser photocoagulation with or without primary lensectomy and not subjected to scleral buckling as a primary procedure. The final reattachment rate was 93.8% (15 of 16 eyes) with no significant difference between the primary scleral buckle group (87.5%) and the non-buckle group (100%). Retinal reoperation and complication rates were higher in the primary buckle group and final visual acuities better in the non-buckle group despite comparable preoperative characteristics.
