Surgical outcome in optic disc pit maculopathy

Abstract

The purpose of this study was to present the surgical outcome in optic disc pit associated maculopathy in a patient who was treated with vitrectomy, internal limiting membrane (ILM) peeling, barrage laser photocoagulation, and silicone oil tamponade. A 21-year-old Indian male was diagnosed with optic disc pit maculopathy in his left eye with a best-corrected visual acuity (BCVA) of 20/200. A 23-gauge pars plana vitrectomy with peeling of ILM was done using brilliant blue dye. After completion of vitrectomy, fluid-air exchange was performed and silicone oil was instilled into eye. Peripapillary endolaser barrage photocoagulation using two rows of low-intensity laser was performed temporally. Silicone oil was removed 4 months after surgery. During the next 24 months, the retina gradually flattened with gradual improvement of BCVA in the left eye. At 24 months, fundus examination showed retinal pigment epithelium atrophy temporal to optic disc not involving the fovea, and optical coherence tomography showed complete resolution of subretinal fluid, with a BCVA of 20/60. The patient maintained the same vision 4 years following the surgery. vitrectomy combined with posterior hyaloid and ILM peeling followed by silicone oil tamponade, with additional laser photocoagulation, was successful for the treatment of optic disc pit maculopathy in our patient. Further studies are warranted to explore the various treatment options and try to set a standard treatment protocol for this rare challenging condition.
