Purpose:
The aim of this study was to evaluate the anatomical and functional outcomes after pars plana vitrectomy with or without circumferential scleral buckling, in patients with retinal detachment secondary to retinal dialysis.
Design:
Case series.
Methods:
A retrospective consecutive case series involving 30 eyes of 30 patients with retinal detachments secondary to retinal dialysis was completed. All 30 patients underwent primary pars plana vitrectomy, with the addition of a circumferential scleral buckle in 24 patients. The main outcome measure was the primary reattachment rate at 6 months after a single surgery.
Results:
Primary anatomical success was achieved in 90% of patients. The final anatomical success rate was 93%, with 4 of 30 eyes still having silicone oil in situ. The main indication for vitrectomy surgery was an inadequate fundal view for scleral buckle surgery alone. The macula was detached in 50% of patients and proliferative vitreoretinopathy grade C was found in 23% of cases. The mean preoperative visual acuity was 20/814 (range 20/20-light perception) and the mean postoperative visual acuity was 20/258 (range 20/20-hand movements).
Conclusions:
Good final anatomical success rates can be achieved with pars plans vitrectomy, plus or minus circumferential buckling, in patients with retinal detachments secondary to retinal dialysis.
