Combined scleral buckle and pars plana vitrectomy as a primary procedure for pseudophakic retinal detachments

Abstract

Background and objective: Pseudophakic and aphakic retinal detachments are associated with a lower percentage of successful primary repair with standard scleral buckling surgery, than phakic retinal detachments. The objective of this study was to determine whether a combined scleral buckle and vitrectomy, as a primary procedure, offers any advantage over conventional scleral buckling in primary pseudophakic and aphakic retinal detachments, without proliferative vitreoretinopathy.

Materials and methods: This was a prospective, non-randomized clinical study. Ninety-four consecutive pseudophakic and aphakic retinal detachments were included in the study. All patients were operated upon by the same surgeon. Each patient underwent a combined scleral buckle and pars plana vitrectomy with perfluorocarbon injection and air-fluid exchange. Each patient was followed by the operating surgeon for a minimum of 6 months. Patients were followed with respect to anatomic reattachment, visual acuity improvement, and surgical complications.

Results: All eyes were anatomically reattached after a single operation. All demonstrated an increase in their visual acuity, and there were no complications attributable to the vitrectomy procedure.

Conclusions: We conclude that such a combined approach to primary pseudophakic and aphakic retinal detachments offers significant benefits to scleral buckling alone. We believe that the improved success rate is a function of vitrectomy contributing to both an improved peripheral visibility, resulting in fewer missed peripheral breaks, and a lower likelihood of proliferative vitreoretinopathy. We recommend this combined surgical approach for all primary pseudophakic and aphakic retinal detachments.
