Inverted ILM Flap Technique in Optic Disc Pit Maculopathy

Abstract

Purpose: To present the outcome of optic disc pit maculopathy (ODPM) managed successfullywith an inverted internal limiting membrane (ILM) flap over the optic disc. A narrative review ofODPM pathogenesis and surgical management techniques are also provided. Case Report: This prospective interventional case series included three eyes of three adultpatients (25–39 years old) with unilateral ODPM and a mean duration of unilaterally decreasedvisual acuity of 7.33 ± 2.40 months (4–12 months). The pars plana vitrectomy with posteriorvitreous detachment induction was performed on eyes, followed by an inverted ILM flap insertionover the optic disc and gas tamponade. Patients were followed for 7–16 weeks postoperatively;best-corrected visual acuity (BCVA) improved dramatically in one patient from 2/200 to 20/25.BCVA in other patients improved two and three lines – to 20/50 and 20/30, respectively. Asignificant anatomical improvement was achieved in all three eyes, and no complication wasdetected throughout the follow-up period. Conclusion: Vitrectomy with inverted ILM flap insertion over the optic disc is safe and can yieldfavorable anatomical improvement in patients with ODPM.
