The depth of the defect varies from the slightest indentation to one-fourth of the diameter of the lens. The commonest position for a coloboma of the lens is at its lower border, but it has been met with elsewhere, and two separate defects have been seen in the margin of the same lens. The suspensory ligament is usually absent in the position of the coloboma, though cases have been observed clinically in which no break could be detected in its Fig. 44.—Section through the front half of an eye lost from glaucoma, which had a congenital coloboma of the iris and lens. The section passes through the seat of the coloboma in both structures. The suspensory ligament is absent opposite the coloboma of the lens and the latter is broader in that situation anterio-posterior than in the rest of its circumference. The angle of the anterior chamber is closed on the opposite side by the root of the iris and there is ectropion of the uveal pigment. Myopia is frequent in these cases. In patients who have had the defect in one eye only it has been observed that the defective eye is myopic and the unaffected eye emmetropic. In eyes which have been examined pathologically with coloboma of the lens an absence of the suspensory ligament at the site of the defect has been found, and the lens in that region was broader antero-posteriorly than in other parts of its circumference (Fig. 44)..
