Retinal detachment with a break at pars plicata associated with congenital malformation of the lens–zonule–ciliary body complex

Retinal detachment with a break at the pars plicata associated with congenital malformation of lens-zonule-ciliary body complex is rare; most reports are of young Japanese male patients with atopic dermatitis. The present case report is the first to describe the condition in a Chinese patient with no atopic dermatitis or trauma history. A 22-year-old male presented with blurred vision in the left eye for 4 months. Fundus examination revealed shallow lower temporal retinal detachment. Further examination with scleral indentation under maximal pupil dilatation identified a break at the far periphery beyond the ora serrata and pars plana. Gonioscopy revealed a pars plicata break at the nonpigmented ciliary epithelium associated with congenital ciliary process hypoplasia and subtle lens defect at the same meridian. The retina was successfully reattached after segmental scleral buckling, cryopexy, and laser photocoagulation.
