PURPOSE: To study macular hole (MH) surgery in terms of baseline demographics, intraoperative complications, post-vitrectomy cataract, reoperation, and visual outcome. DESIGN: National Ophthalmology Database study. PARTICIPANTS: A total of 1078 eyes from 1045 patients undergoing primary MH surgery. METHODS: Participating centers prospectively collected clinical data using a single electronic medical record (EMR) system, with automatic extraction of anonymized data to a national database, over 8 years. The following data were extracted for eyes undergoing MH surgery: demographics, procedure elements, intraoperative complications, visual acuity (VA), and further surgery. MAIN OUTCOME MEASURES: Description of the primary procedures performed, intraoperative complication rate, change in VA, proportion of eyes undergoing subsequent surgery for persisting MH, cataract, or retinal detachment. RESULTS: The median age was 70.3 years, with a 2.2:1 female preponderance. All operations included a pars plana vitrectomy (PPV)-41.1% with hexafluoroethane (C(2)F(6)), 25.6% with perfluoropropane (C(3)F(8)), 24.5% with sulfahexafluoride (SF(6)), 2.2% with air, and 0.4% with silicone oil. A PPV was combined with internal limiting membrane (ILM) peel in 94.1% and cataract surgery in 40.5%. One or more intraoperative complications occurred in 12.4%. The median presenting logarithm of the minimum angle of resolution (logMAR) VA improved from 0.80 to 0.50 after a median follow-up of 0.6 years; 57.8% of eyes improved ≥0.30 logMAR units (∼2 Snellen lines). The choice of gas tamponade did not significantly influence the visual outcome, but eyes undergoing ILM peel were significantly more likely to gain ≥0.30 logMAR units, as were eyes with poor presenting VA. Subsequently, 4.2% of eyes underwent repeat surgery for MH and 2.4% for retinal detachment, and, excluding pseudophakic eyes, 64.6% underwent cataract surgery within 1 year. CONCLUSIONS: This study provides pooled, anonymized data on the demographics, complications, and visual outcome of MH surgery. This may enable vitreoretinal surgeons to benchmark their case-mix and outcomes, and facilitate risk-benefit and cost-benefit analyses.
