Methods
Six eyes of six consecutive patients who underwent pars plana vitrectomy with membrane peeling for VMT were included in this retrospective study. All patients were seen at a single, referral-based retina practice. Each eye underwent complete preoperative ophthalmic examination including best-corrected Snellen visual acuity (VA), biomicroscopy, color fundus photography, and SD-OCT analysis (3D OCT 1000 version 2.00; Topcon Corp, Paramus, New Jersey, USA). This SD-OCT system used in this study
Results
The mean age of the patients was 75.2 years (range, 65 to 82; Table). Two of the patients were male, four were female. The mean preoperative VA was 20/78 (logMAR 0.59; range, 20/40 to 20/200). There were no intraoperative surgical complications. The mean postoperative VA was 20/54 (logMAR 0.43; range, 20/30 to 20/100) with an average follow-up of 32 weeks (range, 1.5 to 95 weeks).
Discussion
In this study, we evaluated patients with prominent vitreomacular traction with SD-OCT and then examined the corresponding vitreous specimen with TEM. By SD-OCT with 3D reconstruction we found the expected cone of vitreous with persistent attachment to the central macula. The eyes had findings consistent with ERM formation in areas of PVD. In addition, the membrane appeared to course up the vitreous cone and formed a hyperreflective encasement of the posterior portion of the persistent vitreous

Mechanistic Insights into the Pathogenesis of Proliferative and Nonproliferative Vitreomacular Traction
2022, American Journal of OphthalmologyCitation Excerpt :The probability of seeing ERM in nonproliferative VMT was comparatively much lower. Concurrence of ERM and thick posterior vitreous in VMT has been reported from intraoperative observations, 3D spectral-domain OCT and histopathological studies.6–8 Although the origin of thick posterior vitreous in VMT is still debatable, the ERM and the thick posterior vitreous are connected together as a result of cellular proliferation.7,23
