Microcornea is characterized by a horizontal corneal diameter of 9 mm or less at birth and less than 10 mm after 2 years of age (Fig 21-2). It is often a component of ocular malformations such as microphthalmia and persistent fetal vasculature and of syndromes such as oculodentodigital, Nance-Horan, and Lenz syndromes.
