cornea plana 2


Definition An über rare autosomal recessive condition (OMIM:217300), characterised by flattening of the forward convex curvature of the cornea, leading to decreased refraction, reduced visual activity, extreme hyperopia (usually plus 10+ d), hazy corneal limbus, opacities in the corneal parenchyma, and marked arcus senilis (often at an early age). Whilst cornea plana 2 has a worldwide distribution, it is more common in the Finns. 

Molecular pathology Defects of KERA, which encodes a keratan sulfate proteoglycan important in developing and maintaining corneal transparency and the corneal stromal matrix, cause cornea plana 2.
