Inverted autologous internal limiting membrane for management of optic disc pit with macular detachment

Abstract

Macular detachment causes visual deterioration in 25-75% of patients with congenital optic disc pit. A number of treatment options have been reported to manage the macular detachment in optic pit. An optic disc pit represents a defect in the lamina cribrosa; theoretically, an ideal procedure to treat optic pit associated macular detachment would be one that prevents the flow of fluid across the pit by creating an additional barrier. We present a new surgical technique that employs an autologous internal limiting membrane (ILM) to create this barrier. The technique involves standard vitrectomy along-with ILM peeling. Subsequently, the peeled ILM was inverted and transplanted onto the optic disc pit to close the optic nerve pit. This technique showed satisfactory anatomic result with good functional improvement in visual acuity.
