Breaks in the pars plicata following surgery for atopic cataract.

Two cases involving retinal detachment caused by breaks in the pars plicata of the ciliary body are presented. In both, retinal detachment developed following surgery for atopic cataract. The residual lens capsules contracted with evidence of fibrotic change. Nonpigmented ciliary epithelium appeared to have become detached and torn by traction through the zonules of Zinn.
