PURPOSE: To evaluate the surgical outcome of vitrectomy and foveal thickness before and after vitrectomy for idiopathic epiretinal membranes. SUBJECTS AND METHODS: Twenty-three eyes of 21 patients with idiopathic epiretinal membranes were analyzed. The mean follow-up period was 17.8 months. In 16 eyes of 14 patients, foveal thickness was measured by optical coherence tomography (OCT). RESULTS: Preoperative visual acuity ranged from 0.1 to 0.7. Postoperatively, 17 eyes achieved a final visual acuity of 1.0 or better, and 21 eyes achieved 0.5 or better. Preoperative foveal thickness ranged from 205 to 575 microns (mean +/- standard deviation, 409.9 +/- 103.3 microns). Postoperatively, mean foveal thickness was 347.7 +/- 106.0 microns (1 week follow up), 338.6 +/- 103.7 microns (2 months), 304.6 +/- 97.0 microns (6 months), and 274.3 +/- 78.7 microns (1 year). There was a weak negative correlation between visual acuity and foveal thickness. CONCLUSION: Visual acuity improves significantly after surgery. OCT is useful for idiopathic epiretinal membrane surgery.
