Refined Internal Limiting Membrane Inverted Flap Technique for Intractable Macular Detachment with Optic Disc Pit.

PURPOSE: To report a surgical technique for retinal detachment associated with optic disc pit (ODP) by using an internal limiting membrane (ILM) inverted flap as an obstacle between the vitreous cavity and subretinal space.

CASE PRESENTATION: A 43-year-old man presented with decreased visual acuity in the right eye for 1 week due to macular detachment associated with ODP. After 2 unsuccessful surgeries, the retina was reattached by vitrectomy with an ILM inverted flap onto the ODP.

CONCLUSION: Covering the pit with an inverted ILM flap is a reliable method for intercepting fluid from the vitreous cavity. Immediate absorption of subretinal fluid may lead to early macular attachment. This technique would be effective in managing ODP.
