Clinical Implication of Retinal Nerve Fiber Layer Schisis and Macular Fluorescein Leakage in Primary Idiopathic Epiretinal Membrane

Abstract

We evaluated the relationship between macular fluorescein leakage and retinal nerve fiber layer (RNFL) schisis and investigated the visual prognostic values after pars plana vitrectomy (PPV) and idiopathic epiretinal membrane removal.Methods: We analyzed the correlations between preoperative optical coherence tomography (OCT) parameters and macular leakage. The final best-corrected visual acuity and central macular thickness were compared according to the presence or absence of macular leakage and RNFL schisis.Results: In 80 eyes with idiopathic epiretinal membrane treated with PPV and membrane peeling, preoperative macular leakage was associated with the presence of preoperative RNFL schisis and inner nuclear layer microcysts. Eyes with both macular leakage and RNFL schisis showed worse postoperative best-corrected visual acuity than those without both factors.Conclusion: In the presence of macular fluorescein leakage and RNFL schisis, postoperative best-corrected visual acuity is worse, and improvements in the central macular thickness are greater than those in the absence of both factors.

Clinical characteristics and surgical outcomes of pediatric idiopathic and secondary macular epiretinal membrane

“…Macular epiretinal membrane (ERMs) is characteristic of a proliferative and nonvascular membrane occurring on the retinal surface, causing focal edema and retinal wrinkling, and resulting in reduced visual acuity (VA) [1][2]. Idiopathic macular ERMs usually affect adult patients over 50 years of age, surgical removal of those macular ERMs is well established and may lead to improvement in postoperative visual function [3][4]. Idiopathic macular ERMs may occasionally affect young even pediatric patients and cause signi cant visual disturbances [5].…”
