Muller Cell Role in Foveolar Schisis, Comparative Review of Three Cases

Abstract

Three cases of non-high myopic foveolar schisis and discuss factors that affect Muller cell integrity and foveolar schisis development are documented. Case 1: A 67-year-old Asian female with best corrected visual acuities (BVA) of 20/20 right eye (OD), left eye (OS) and an epiretinal membrane with an underlying foveolar schisis OD. Case 2: A 60-year-old Hispanic female with sudden decreased vision OD and BVA of 20/30 OD, 20/20 OS. A macular hole, complete posterior vitreous detachment and surrounding foveolar schisis was present OD. Following surgical repair, BVA OD improved to 20/20 with the macula re-attached. Case 3: An otherwise healthy and generally asymptomatic 52-year-old Hispanic female with BVA of 20/20/OD and OS, presented with a foveolar schisis OD. In all cases, the parafoveal Z- shaped Muller cells demonstrated a reduction of the subtended angle θ towards the center of the fovea (or increases farther from the center of the fovea). We conclude that a greater subtended angle by the parafoveal Z-shaped Muller cells in all th ree cases of foveolar schisis may help explain the good and stable visual acuity.
