mac·ro·cor·ne·a (m k r -kôr n - )n. An unusually large cornea. Also called megalocornea. |
keratoglobus
A rare, usually bilateral, protrusion of the cornea with general thinning, especially in the periphery. The condition is usually present at birth and generally does not progress. Some cases may be acquired perhaps as the end-stage of keratoconus. The diameter of the cornea is normal or slightly increased and the intraocular pressure is normal as the condition is not associated with congenital glaucoma. Complications include perforation after minor trauma and corneal hydrops. It is sometimes associated with Leber's congenital amaurosis, Ehlers-Danlos syndrome and blue sclera. Syn. macrocornea. See megalocornea.
