Coloboma of the lens is often associated with colobomata of the uveal tract in the inferior quadrant. A case of coloboma, nasally situated, is herein reported which is believed to have developed as a result of congenital cystic formations in the ciliary processes pressing upon the equator of the lens.
Report of a Case
A white girl was first seen at the age of 6 years because of a concomitant convergent strabismus. The left eye was normal in all respects, with the corrected vision 20/20. Vision in the right eye was limited to counting fingers at one foot.Thorough examination of the right eye after maximal dilatation revealed these findings: (1) strands of persistent pupillary membranes; (2) an irregular coloboma of the lens equator on the nasal side through which, with pupil dilated, the normal zonular fibers could be seen bridging the gap between the coloboma line and the ciliary
