Summaries for Cataract Microcornea Syndrome

NIH Rare Diseases : 50 the following summary is from orphanet, a european reference portal for information on rare diseases and orphan drugs.orpha number: 1377disease definitioncataract-microcornea syndrome is characterized by the association of congenital cataract and microcornea without any other systemic anomaly or dysmorphism.epidemiologyto date, more than 15 families showing microcornea-cataract syndrome have been described.clinical descriptionclinical findings include a corneal diameter inferior to 10 mm in both meridians in an otherwise normal eye, and an inherited cataract, which is most often bilateral posterior polar with opacification in the lens periphery. the cataract progresses to form a total cataract after visual maturity has been achieved, requiring cataract extraction in the first to third decade of life. microcornea-cataract syndrome can be associated with other rare ocular manifestations, including myopia, iris coloboma, sclerocornea and peters anomaly (see this term).etiologythere is marked genetic heterogeneity. mutations have been described in several crystallin genes (cryaa, crybb1, crygd), and in the gap junction protein alpha 8 gene (gja8).diagnostic methodsophthalmologic and general examination allows other syndromes to be excluded.genetic counselingtransmission is in most cases autosomal dominant, but cases of autosomal recessive transmission have recently been described.management and treatmentcataract surgery has to be performed in order to restore visual acuity and avoid amblyopia.prognosisvisual acuity after uncomplicated cataract extraction is relatively good.visit the orphanet disease page for more resources. last updated: 10/25/2007
