  • Abstract
  • Look Inside

A 4-year-old boy was referred to us for decreased visual acuity in his right eye. His corrected visual acuity was 0.2 right and 1.0 left. The central portion of the crystalline lens was protruded posteriorly and was opacified. The right eye was diagnosed with posterior lenticonus. The left eye was intact. He underwent cataract surgery at the age of 9 years because of advanced cataract. The surgically obtained posterior capsule was subjected to immunohistochemical studies. The tissue contained no capsular basement membrane. It was positive for collagenⅠ,ⅣandⅤ,laminin,and fibronectin. Cells abjacent to the posterior capsule was positively stained for vimentin,α-smooth muscle actin,and integrinα5. The findings were suggestive of fibroblastic overgrowth of extraordinary lens epithelial cells as the pathogenesis.
