Postoperative visual acuity at 1 year did not differ among 4 methods of primary retinal detachment repair, including scleral buckling, vitrectomy, combined scleral buckling and vitrectomy, and pneumatic retinopexy surgery, according to a study in Retina.¹

Shlomit Schaal, MD, PhD, of the University of Louisville, KY, and colleagues conducted a retrospective, interventional, comparative case series of 1226 patients with primary retinal detachment. All patients completed 1-year follow-up and were divided into 4 groups based on method of repair: scleral buckling surgery (n=322), pars plana vitrectomy surgery (n=442), a combination of scleral buckling and vitrectomy surgery (n=316), and pneumatic retinopexy surgery (n=56). Reattachment success rates, pre- and postoperative visual acuity, complications, and change in refractive error were assessed.

The initial success rate for retinal reattachment was 86% for scleral buckling only, 90% for vitrectomy only, 94% for a combination of scleral buckling and vitrec-tomy, and 63% for pneumatic retinopexy surgery. Patients who underwent pneumatic retinopexy had a lower initial success rate, but there was no statistically significant difference in initial reattachment rates among the other 3 groups. Furthermore, there was no statistically significant difference in final visual acuity among the 4 groups. Complication rates varied among the techniques used, the investigators concluded.
