In each eye, average RNFL thickness measurements were obtained in temporal, superior, nasal, and inferior quadrants. A single index of average RNFL thickness throughout 360° also was obtained. The RNFL thickness parameters (μm)(mean and SD) measured during the study in both groups are presented in [Table 2]
