Abstract
BACKGROUND: Pars plana vitrectomy (PPV) procedures are used for the surgical treatment of macular hole retinal detachment (MHRD) associated with high myopia. Re-detachment of the retina has been reported in MHRD associated with high myopia. Our aim was to evaluate the 1-year outcomes of vitrectomy, performed using an inverted internal limiting membrane (ILM) flap technique with gas tamponade, in five cases of MHRD associated with high myopia. METHODS: We performed a retrospective review of medical records of five consecutive cases of highly myopic MHRD. The following postoperative data were collected: refractive error, best-corrected visual acuity, intraocular pressure, ophthalmic fundus examination findings, ocular coherence tomography at 1, 3, 6, and 12 months postoperatively; duration of the follow-up period; and intra- and postoperative complications. The primary endpoint of the study was the rate of postoperative retinal reattachment and macular hole (MH) closure. Paired t-tests were conducted to evaluate postoperative changes. RESULTS: Mean visual acuity improved significantly (P = 0.008), with an improvement of ≥2 lines on LogMAR value gained in three of the five eyes. Retinal reattachment was maintained in all cases, with no cases of MH reopening identified over the mean follow-up period of 20.2 months. No complications were identified in any eye. CONCLUSIONS: The inverted ILM flap technique and gas tamponade provided primary retinal reattachment and MH closure over the ≥12-month follow-up period.
