Optic Disc Pit Maculopathy: One-Year Outcomes of Pars Plana Vitrectomy with Foveal Sparing Inverted Internal Limiting Membrane Flap

Purpose To evaluate the anatomical and visual outcomes in optic disc pit maculopathy following pars plana vitrectomy (PPV) with inverted internal limiting membrane (ILM) flap Methods Retrospective interventional case series of 10 patients diagnosed with serous macular detachment secondary to optic disc pit who underwent PPV with inverted ILM flap and were followed up for a year. Results A p-value of less than 0.05 was defined as statistically significant. The mean age of patients was 27.2 ± 10.6 years, preoperatively the mean best-corrected visual acuity of the logarithm of the minimum angle of resolution was 0.91 ± 0.42 (approximate Snellen equivalent 20/162), which improved to the logarithm of the minimum angle of resolution of 0.58 ± 0.29 (approximate Snellen equivalent 20/76) at end of one year, (p=0.008). The mean central macular thickness was 804.9 ± 294.1 m which improved to 273.4 ± 102.54 m, (p=0.002). After surgery, at end of one year, 60% of patients (6/10) had 15- or more-than-15-letter improvement of vision on Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing, 20% (2/10) gained a 10-letter improvement and 20% (2/10) retained the same vision. Conclusion PPV with inverted ILM flap can be considered as a good approach for the management of serous macular detachment secondary to optic disc pit and produce good anatomical and visual results at one year with stabilization of the disease.
