Introduction: To evaluate the anatomical and functional outcomes of pars plana vitrectomy (PPV) and epiretinal membrane (ERM) peeling in patients with retinal vein occlusion (RVO) and secondary ERM. Methods: Retrospective, multicenter study including patients with RVO and ERM who underwent PPV and ERM peeling with or without phacoemulsification. Demographic, clinical, surgical, and optical coherence tomography (OCT) features were recorded at the time of ERM peeling (baseline). Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were longitudinally collected up to 36 months after surgery. Clinical factors associated with BCVA and CMT and disappearance of macular edema during follow-up were investigated. Results: Twenty-one eyes of 21 patients with a median follow-up of 18 months were included. The BCVA improved significantly after ERM peeling (baseline vs. 24 months, p = 0.01). Absence of the external liming membrane/ellipsoid zone on OCT was associated with worse visual outcomes (regression estimate [95% confidence interval, CI] = 0.93 [0.39–1.48] logMAR, p = 0.004). Eyes with disorganization of the inner retinal layers at baseline had higher CMT values at each visit (regression estimate [95% CI] = 114.1 [78.9–219.4] μm, p = 0.004). Older age at the time of RVO (p = 0.03) and branch RVO (p = 0.04) were risk factors for persistent macular edema after ERM removal. Conclusion: PPV and ERM removal provided encouraging functional and morphological results in eyes with RVO, with disappearance of macular edema in most eyes. The integrity of the outer retina and preservation of inner retinal segmentation were associated with better visual and anatomical outcomes after ERM removal, respectively.

Abstract

Introduction: To evaluate the anatomical and functional outcomes of pars plana vitrectomy (PPV) and epiretinal membrane (ERM) peeling in patients with retinal vein occlusion (RVO) and secondary ERM. Methods: Retrospective, multicenter study including patients with RVO and ERM who underwent PPV and ERM peeling with or without phacoemulsification. Demographic, clinical, surgical, and optical coherence tomography (OCT) features were recorded at the time of ERM peeling (baseline). Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were longitudinally collected up to 36 months after surgery. Clinical factors associated with BCVA and CMT and disappearance of macular edema during follow-up were investigated. Results: Twenty-one eyes of 21 patients with a median follow-up of 18 months were included. The BCVA improved significantly after ERM peeling (baseline vs. 24 months, p = 0.01). Absence of the external liming membrane/ellipsoid zone on OCT was associated with worse visual outcomes (regression estimate [95% confidence interval, CI] = 0.93 [0.39–1.48] logMAR, p = 0.004). Eyes with disorganization of the inner retinal layers at baseline had higher CMT values at each visit (regression estimate [95% CI] = 114.1 [78.9–219.4] μm, p = 0.004). Older age at the time of RVO (p = 0.03) and branch RVO (p = 0.04) were risk factors for persistent macular edema after ERM removal. Conclusion: PPV and ERM removal provided encouraging functional and morphological results in eyes with RVO, with disappearance of macular edema in most eyes. The integrity of the outer retina and preservation of inner retinal segmentation were associated with better visual and anatomical outcomes after ERM removal, respectively.
