INVERTED INTERNAL LIMITING MEMBRANE-FLAP TECHNIQUE FOR OPTIC DISK PIT MACULOPATHY: MORPHOLOGIC AND FUNCTIONAL ANALYSIS.

PURPOSE: To analyze morphologic and functional changes after inverted internal limiting membrane-flap technique for optic disk pit maculopathy using optical coherence tomography, multifocal electroretinography, and microperimetry. METHODS: One case report. RESULTS: A 30-year-old woman presented us with decreased visual acuity (20/63) in the left eye because of retinoschisis and serous macular detachment associated with optic disk pit. Optical coherence tomography did not localize the source of intraretinal and subretinal fluid. A partial flattening of serous detachment after vitrectomy with internal limiting membrane peeling, inverted internal limiting membrane-flap technique, and gas tamponade was reported. Visual acuity and multifocal electroretinography improved while retinal sensitivity decreased at microperimetry during 3 months of follow-up. CONCLUSION: Optical coherence tomography is helpful to assess the effectiveness of surgical maneuvers to treat optic disk pit maculopathy. Multifocal electroretinography and microperimetry might offer additional tools for follow-up analysis of retinal function after surgery.
