DESCRIPTION: Abnormal smallness of one or both eyes; congenital, and almost always hereditary (usually recessive, but may also be dominant). Other ocular abnormalities also occur, including cataract, glaucoma, aniridia, and coloboma. Systemic and anatomic abnormalities also often occur; these include: polydactyly, syndactyly, clubfoot, polycystic kidneys, cystic liver, cleft palate, and meningoencephalocele. Deficient vision is the rule.
TREATMENT: Lens correction for refractive errors, often tinted; lighting according to needs, to control glare.
IMPLICATIONS: Genetic counseling is indicated.
