91492 Early-onset non-syndromic cataract

definition

Early-onset non-syndromic cataract is a rare, genetic, non-syndromic developmental defect of the eye, with high clinical and genetic heterogeneity, most frequently characterized by bilateral, symmetrical, non-progressive cataracts which present at birth or in early-childhood. Additional ocular manifestations (e.g. anterior segment dysgenesis, colobomas, nystagmus, microcornea, microphthalmia, myopia) may be associated, however other organs/systems are usually not affected.
