title: Uncommon ocular changes in Down's syndrome (mongolism).
abstract: A one-year-old White female mongoloid child was seen with typical palpebral fissures, esotropia, myopic astigmatism, and nystagmus. Additional uncommon ocular findings included ganglionic neuroretinal hypoplasia (hypoplasia of the optic nerve) and bilateral congenital impatency of the nasolacrimal duct. An active search for these ocular changes is recommended in cases of Down's syndrome.
