Long-standing anterior dislocation of the crystalline lens.

We believe this is the first reported case of an anteriorly dislocated lens that produced no pain or discomfort for at least 4 months, ie, March to July 1972. Even after July, the symptoms were not severe enough for this man to seek medical attention until September 1972. The lens may have been dislocated as early as age 5 since, according to his history, surgery was suggested at age 7 for the right eye. A pupillary block may have developed in March 1972, causing an intraocular pressure rise which eventually led to enucleation in September 1972. The microscopic evidence of fibrovascular adhesions of the lens to the iris and cornea documents the long-standing nature of this condition.
