Purpose: To determine the rate of anatomical closure and visual outcome following vitreous surgery for idiopathic macular hole (IMH) using Optical Coherence Tomography (OCT). Methods: Interventional case series. 23 eyes with idiopathic macular hole having a preoperative OCT macular hole diameter ranging from 280 to 1051 microns underwent vitrectomy with internal limiting membrane peeling and perfluoropropane gas injection. Outcome measures: Primary outcome: Anatomical closure of macular hole demonstrated by OCT. Secondary outcome measures: Visual acuity and complications. Results: Type I closure was seen in 14 eyes and type II closure was seen in 7 eyes. Anatomical closure was not achieved in 2 eyes with macular hole diameter of greater than 400 microns. Conclusion: OCT measurements are useful to predict the anatomical and visual outcomes following surgery for idiopathic macular hole.
