Cataract-microcornea syndrome

ORPHA:1377Malformation syndrome

What it is

A rare syndromic, genetic cataract characterized by the association of congenital cataract and microcornea without any other systemic anomaly or dysmorphism. Clinical findings include a decreased corneal diameter (inferior to 10 mm) in both meridians in an otherwise normal eye, and an inherited cataract, which is mostly bilateral posterior polar with opacification in the lens periphery that progresses to form a total cataract after visual maturity has been achieved. Association with other ocular manifestations, including myopia, iris coloboma, sclerocornea and Peters anomaly may be observed.

ICD-10 codes

Q13.8filed under a broader ICD-10 category — shared with 13 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
