OBJECTIVE: To evaluate the visual outcome after a second surgical attempt to close idiopathic full-thickness macular holes (FTMH) in patients who underwent unsuccessful primary surgery and in patients with reopened FTMHs.
DESIGN: Retrospective single-center case series.
PARTICIPANTS: Five hundred thirty-two patients underwent surgery for FTMH in St. Paul's Eye Unit, Liverpool, United Kingdom, between March, 1995, and March, 2005. Fifty-one patients had unclosed FTMHs (unclosed group) and 21 patients had reopened FTMHs after initially successful surgery (reopened group).
METHODS: All patients underwent a second pars plana vitrectomy. Autologous platelet concentrate and perfluoropropane endotamponade were used. Internal limiting membrane peeling was carried out in selected cases. Patients were instructed to maintain a face-down position for 2 weeks after the surgery.
MAIN OUTCOME MEASURES: Anatomic and visual results.
RESULTS: All patients in the reopened group and 76% of patients in the unclosed group achieved successfully closure of the FTMH after the second surgery. Mean decimal Snellen visual acuity (VA; +/-standard deviation [SD]) before the second surgery was 0.14+/-0.10 (range, 0.01-0.33) in the reopened group and 0.10+/-0.07 (range, hand movements [HM]-0.33) in the unclosed group. The best VA was achieved after cataract surgery; the mean best VA (+/-SD) in the reopened group was 0.42+/-0.31 (range, 0.05-1) and in the unclosed group was 0.19+/-0.14 (range, HM-0.66).
CONCLUSIONS: Reoperating on reopened FTMH resulted in 100% anatomic closure and significant improvement in vision. In contrast, reoperating on patients with initially unsuccessful surgery resulted a lower anatomic closure rate and relatively poor final vision even if their macular holes were closed successfully. This information may help surgeons and patients decide whether to undertake a second operation.
