  • Abstract
  • Look Inside

A 4-month-old male infant presented with bilateral leukocoria. Both eye showed absent anterior chamber, posterior synechia, cataract and retrolental white mass. The family history was negative. Ultrasonography showed a mass in the vitreous simulating bilateral retinoblastoma. Magnetic resonance imaging (MRI) showed bilateral persistent hyperplastic primary vitreous. MRI also showed the absence of optic chiasma and the optic tract. The infant showed low audio-brain responses, suggesting hearing impairment. We performed DNA analysis by PCR and direct sequence technique to rule out sporadic Norrie's disease. There were no point mutations in the known range of the Norrie's disease gene. Further studies are under way to detect mutations in other ranges of the gene.
