Preoperative and postoperative spectral-domain optical coherence tomography (OCT) was examined for macular thickness and macular volume. Outcomes and variables were analyzed using the two-tailed t-test and Spearman&#39;s rank correlation coefficient.Results: Twenty-four eyes from 11 men and 10 women of mean age 69 (range 55&ndash;84) years were included. Four patients (17%) had chronic macular edema from uveitis, four (17%) from retinal vein occlusion, and 16 (67%) from diabetes. Mean visual acuity was 20/103 preoperatively and 20/87 postoperatively (P = 0.55). Sixty-three percent of the eyes had improved vision (47% better than 20/40), 21% maintained the same vision, and 17% had worse vision. Forty-seven percent of improved eyes and 30% of total eyes gained more than two lines of visual acuity (range -9 to +7 lines). Mean macular thickness was 455 &micro;m preoperatively and 396 &micro;m postoperatively (P = 0.29). Mean macular volume was 7.9 mm3 preoperatively and 7.5 mm3 postoperatively (P = 0.51). The strongest predictor of postoperative visual acuity was initial visual acuity (r = 0.673, P = 0.0003).Conclusion: Even though a majority of patients had improved vision and decreased macular thickening after 25-gauge pars plana vitrectomy with internal limiting membrane peeling for chronic macular edema of various etiologies, the difference in visual acuity or macular thickening did not reach statistical significance.Keywords: chronic macular edema, diabetes mellitus, internal limiting membrane peeling, 25-gauge vitrectomy, uveitis, vein occlusionCho MD&#39;Amico DJDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 981-989 (2012)
