Abstract:
PURPOSE:To describe the clinical characteristics of and risk factors for the development of optic neuropathy after pars plana vitrectomy (PPV) for macula-sparing primary rhegmatogenous retinal detachment (RRD) repair. DESIGN:Retrospective case-control study. PARTICIPANTS:Seven patients who underwent PPV for macula-sparing primary RRD with subsequent development of optic neuropathy and 42 age- and gender-matched control patients undergoing PPV for macula-sparing primary RRD. METHODS:Retrospective chart review of medical and surgical records. MAIN OUTCOME MEASURES:Clinical features of patients who developed optic neuropathy after PPV for macula-sparing RRD and analysis of potential risk factors (age, gender, medical history, surgical technique, intraoperative ocular perfusion pressure [OPP], and operative time). RESULTS:At last follow-up, all 7 patients with optic neuropathy had visual acuity less than 20/200, relative afferent pupillary defects, optic nerve pallor, and visual field defects. A total of 5 of 7 patients (71%) demonstrated intraoperative reduced OPP with associated systemic hypotension compared with 7 of 42 patients (17%) in the control cohort (P = 0.01). CONCLUSIONS:Optic neuropathy after PPV for macula-sparing primary RRD is a rare but potentially devastating complication. Although the cause is often unclear, reduced ocular perfusion due to intraoperative systemic hypotension may be a contributing risk factor in some eyes.
