This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. As the crystalline lens hardens with age, the lens zonules pull away from the iris and the syndrome lessens and stops. The main risk factor is nearsightedness. Genetic factors may also play a part in the transition from syndrome to the glaucoma condition.
