Hospices Civils de Lyon54 enrolled

Overview

The aim of this study is to evaluate the correlation of retinal nerve fiber layer (RNFL) thickness measured using spectral domain optical coherence tomography (SD-OCT) and scanning laser polarimetry (SLP) in uveitic eyes compared to healthy eyes. A descriptive, observational, prospective, consecutive, cross-sectional, controlled, mono-center case series was conducted from May to October 2015. Clinical characteristics, best-corrected visual acuity, intra-ocular pressure, RNFL thickness measurement with SD-OCT and SLP using GDx variable corneal compensation (GDx VCC) were performed for each patient. An evaluation of anterior chamber inflammation with laser flare cell meter was also carried out. Correlations between SD-OCT and GDx VCC RNFL measurement were evaluated by linear regression analysis.
