Two siblings with small eyes.

Posterior microphthalmos is a rare congenital bilateral eye disorder, of which the posterior segment is abnormally small. Additional features include high hypermetropia and a tendency to uveal effusion. We report two siblings who present with high hypermetropia and other features of posterior microphthalmos. Fundus examination revealed the typical crowding of the optic disc and retinal folds. We discuss clinical characteristics, pathogenesis and complications of this disorder.
