  • Abstract
  • Look Inside

A 9-year-old girl with Hurler-Scheie compoundwas referred to us for evaluation of ocular compli-cations.Both corneas showed hazy stroma. Thediffuse corneal cloudiness gradually increased withthe visual acuity reduced to hand motion bilaterallyduring the ensuing 4 years.We performed penetrat-ing keratoplasty in her left eye at 14 years of age.The excised cornea was submitted to histopath-ological studies.

Light microscopy showed alcian-blue positivegranules in epithelial cells, keratocytes.and endoth-elial cells. Most of the cellular elements werevacuolated by electron microscopy.These vacuolescontained electron-dense inclusions of variableshapes. Abnormal collagen fibers were observed,suggesting pathological metabolic process in thesynthesis of collagen fibers.
