On the growth of the ciliary body away from the sides of the lens the part of it opposite the gap in the suspensory ligament is not drawn upon in the same way as elsewhere. The absence of traction on the anterior and posterior sur- faces of the lens capsule prevents the lens fibres from becom- ing compressed and bent in that position. The defect in the transverse diameter is compensated for by an increase in the anterio-posterior. The lens is there rounder than Fig. 45.—Section of the anterior half of the eye of an infant aet. 7 weeks. It shows a congenital anterior staphyloma with anterior synechiae of the iris. Also lenticonus anterior. The ciliary processes are adherent to the posterior surface of the lens. The fibres of the suspensory ligament which should go to its anterior s\irface have failed to develop. normal, as in accommodation when the suspensory ligament is relaxed; hence the frequency with which myopia is met with in these cases. The variations in the shape of the defect in the lens margin in these cases is attributable to varying degrees of defect in the suspensory ligament. The bosses projecting from a straight margin are accounted for by the presence of.
