title: Bilateral congenital macular coloboma in a boy with Down syndrome.
abstract: OBJECTIVE
  To describe macular coloboma in Down syndrome.
  
  
  METHODS
  A 12-year-old boy with Down syndrome underwent ophthalmologic examination.
  
  
  RESULTS
  The patient had a circumscribed, round defect about 1 disc diameter, with bared sclera at the base and pigment clump at the macula in both fundi. His poor visual acuity was unchanged since childhood. The results of serum IgG and IgM titers for Toxoplasma gondii were negative.
  
  
  CONCLUSIONS
  Congenital macular coloboma associated with Down syndrome, as demonstrated in our patient, may not have occurred by chance.
