Surgical Approaches to Optic Disc Pit Maculopathy: A Clinical Case Series

Abstract

The purpose of this study was to compare the clinical outcomes of 13 patients with optic disc pit maculopathy (ODP-M) – progressive visual loss, serous macular detachment, and/or intraretinal fluid – who underwent different surgical approaches. This was a retrospective study including a consecutive sample of 13 patients aged 13–74 years (mean 35.38 ± 19.66 years) diagnosed with ODP-M and submitted to vitreoretinal surgery between 2005 and 2021. All patients underwent pars plana vitrectomy, posterior hyaloid detachment, and gas tamponade. Endolaser photocoagulation was applied to the temporal margin of the optic disc in 8 cases; internal limiting membrane (ILM) peeling was performed in 9 cases; and ILM inverted flap technique in 5 cases. Stuffing of the pit with an ILM flap was performed in 3 cases. Mean best-corrected visual acuity improved from 20/200 (1.04 ± 0.56 LogMAR) to 20/50 (0.43 ± 0.54 LogMAR) within 4–36 months. Central retinal thickness decreased from 587.5 ± 158.01 μm to 253.9 ± 33.55 μm, and 7 out of 10 patients had complete resolution of intraretinal fluid. All patients had complete retinal reattachment; however, a few years after surgery, 4 patients had recurrence of serous retinal detachment. The only adjunctive technique associated with greater visual improvement was endolaser (p = 0.033) and not performing peeling of the ILM was also associated with better visual results (p = 0.013), independently of preoperative visual acuity or age at the time of surgery. None of the adjunctive procedures was a significant predictor of better anatomical outcomes. In conclusion, all of these approaches for the surgical management of ODP-M were safe and effective. In this study, vitrectomy with endolaser was a good option for management of ODP-M.
