Lamina Cribrosa Depth is Associated With the Cup-to-Disc Ratio in Eyes With Large Optic Disc Cupping and Cup-to-Disc Ratio Asymmetry

To investigate the lamina cribrosa (LC) depth and its relationship with the cup-to-disc ratio (CDR) in the eyes with generalized increased optic disc cupping and CDR asymmetry.Glaucoma suspect subjects with a CDR≥0.7, CDR asymmetry ≥0.2 in the absence of visual field (VF) loss, and normal control subjects were enrolled. The optic nerve head was imaged using the enhanced depth imaging modes of Spectralis optical coherence tomography. The LC depth...
