Fig. 7. In this goniophotograph, the angle is moderately wide open. As one looks just anterior to the edge of the peripheral iris (arrow), one sees the dark ciliary band, white scleral spur, and trabecular meshwork, which is moderately dark and pigmented in this eye. Schwalbe's line anterior to the trabecular meshwork is not visible in this photo. Such an angle is much too wide to be susceptible to primary angle-closure glaucoma.
