Abstract
- Microphthalmic globes vary in size from nearly normal to microscopic foci of tissue that may escape clinical dectection. Most of microphthalmic eyes may be associated with other structural anomalies. Pure microphthalmos or nanophthalmos is a rare condition in which the eye is reduced in size but absence of other structural malformations. It is thought to represent arrested development after closure of the embryonic fissure(7th weeks). Most nanophthalmic cases apparently occur sporadically although familial cases are occasionally seen. The eyes are usually deeply set in small orbits with narrow palpebral fissures. The microphthalmic eyes often associated with marked hypermetropia and occasionally with macular hypoplasia and angle closure glaucoma. In most oases the vision is subnormal and nystagmus and strabismus may occur. Glaucoma usually occur in the fourth and sixth decades of life. A 16 years old Korean girl was found to have bilateral microphthalmos with absence of other ocular or systemic abnormalites.
