Purpose: To compare the surgical results of vitrectomy and scleral buckling for uncomplicated superior retinal detachment caused by flap tears.
Methods: Included in the study were 225 patients (225 phakic eyes) undergoing primary surgery by three surgeons between January 1990 and December 1996 for superior retinal detachment caused by flap tears (138 eyes by scleral buckling, 87 eyes by vitrectomy); all patients had been followed up for longer than 6 months after surgery. The choice of one of the two procedures was based on each surgeon's preference. The surgical outcome and the rate of complications were retrospectively compared between the two groups of eyes.
Results: Initial and final anatomical success rate were 92% and 100% after each procedure. Retinal redetachment after the initial procedure was due to new retinal breaks in 5 eyes, reopening of original breaks in 2 eyes of vitrectomy cases, and due to malpositioned buckle in 11 eyes of scleral buckling cases. Proliferative vitreoretinopathy occurred in 3 eyes of vitrectomy cases.
Conclusion: Primary vitrectomy was as successful as scleral buckling for treating superior rhegmatogenous retinal detachment. Even though the high incidence of postoperative cataract formation was the major drawback, vitrectomy had some advantages over scleral buckling.
