Fig 2. Measurement of the lamina cribrosa (LC) curvature index in healthy eye.

Fig 2

Horizontal and vertical optic disc scans of a 53-year-old healthy woman. The image delineated with yellow guidelines is the same as that depicted on the left side. The horizontal and vertical mean anterior laminar insertion depth (ALID) was 238.8 μm and 311.9 μm, respectively. The horizontal and vertical mean LC depth was 278.5 μm and 325.7 μm, respectively. The horizontal LC curvature index was 39.8 μm and the vertical LC curvature index was 13.8 μm. The yellow-shaded area exhibits the degree of the posteriorly located anterior LC surface according to the mean level of the anterior laminar insertion (ALI).
