Use of intravitre as injections in scleral buckling.

Objective To evaluate the clinical result of the intravitreal gas injection in scleral buckling surgery. Methods A consecutive series of eyes treated with intravitreal gas injection in the scleral buckling between January 1996 and October 1999 were compared with a group of eyes treated by scleral buckling (without gas injection). Results Single procedure reattachment rate was significantly higher for scleral buckle eyes (137 of 150 eyes, 91.33%) than for intravitreal gas injection in the scleral buckling eyes (37 of 48 eyes, 77.08% P 0.01). Correspondingly, reoperation rate was significantly high for intravitreal gas injection in the scleral buckling eyes (11 of 48 eyes, 22.92%) than for scleral buckle eyes (13 of 150 eyes, 8.77%). Final visual outcome did not differ significantly between the two procedures. Conclusions Intravitreal gas injection may use in scleral buckling in the management of primary rhegmatogenous retinal detachment. There are some complications such as higher rates of persisting vitreoretinal traction, new retinal breaks.
