Microphthalmos is a rare congenital anomaly characterized by reduced eye size and visual deficits of variable degree. Sporadic and hereditary microphthalmos have been associated with heterozygous mutations in genes fundamental for eye development. Yet, many cases are idiopathic or await the identification of molecular causes. Here we show that haploinsufficiency of Meis1, which encodes a transc...

THE term microcornea should be reserved for the condition wherein an abnormally small cornea (diameter less than 11 mm.) occurs in an otherwise relatively normal eye (Mann, 1957). Friede (1922) suggested the term "anterior microphthalmos", because the whole of the anterior segment of the eye seems to be small. The rectus muscles are inserted abnormally far forwards, and the corneal curvature te...
Background: Microphthalmia is defined as a globe with a total length that is at least two standard deviations below the mean for age. It can be isolated or occur with other anomalies or as part of a syndrome. Objective: The aim of our work was to evaluate any functional or structural abnormality along the whole visual system in microphthalmic eyes. Patient and Methods: The study included 70 eye...
A 920-g male infant born with features of Potter's syndrome had multiple ocular anomalies. Ocular abnormalities included absence of keratocytes in the inner central corneal stroma, cataract with retention of cell nuclei in the nucleus of the lens, hypoplasia of the ganglion cell and nerve fiber layers of the retina, and absence of nerve bundles in the optic nerve. Other ocular findings includin...
CASE REPORT A 5-year-old male presented with bilateral poor vision, esotropia and a previous diagnosis of cataract since he was 1 year old.
