Example of pooling the data for an individual optic nerve head. (A) Measurements were made on the set of images taken of the sections cut from between the termination points of Bruch’s membrane. (B) The nine measurement points for anterior laminar position and thickness (see Fig 1) from each section image were projected onto a confocal scanning laser tomographic image of the measured optic nerve head. (C) The measurement points were subdivided into central, superior, inferior, nasal, and temporal regions (see methods for details). (D) Vertical scleral canal diameter and anterior scleral canal wall geometry measurements were made only within the middle 15 section images. (Adapted from Bellezza et al⁷.)
