Displacements of the lens can be classified into three groups, namely, congenital, traumatic, and spontaneous (or consecutive). In nearly all of the cases in these types the primary disturbance is in the lens zonule, which is the most important structure in maintaining the position of the lens. In the congenital group there is a failure of development of the normal anatomic relations of the lens zonule and the lens may become displaced before birth or in postnatal life, even several decades after birth. In the traumatic type of displacement there is an actual tearing, directly or indirectly, of the zonules. The spontaneous type results from some ocular disorder, such as uveal inflammation, high myopia, hydrophthalmos, or hypermature cataract. The mechanism involved here consists of zonular or vitreal degeneration with subsequent displacement of the lens. Traction bands pulling the lens out of position have been previously observed. These have developed following
