Cornea Plana 1
Cornea plana 1 (CNA1) is a congenital disorder that causes the cornea to flatten and the angle between the sclera and cornea to shrink. This could result in the early development of arcus lipoides, hazy corneal limbus, and hyperopia. Cornea plana 1 is an autosomal dominant disorder. Signs and symptoms Cornea plana commonly presents as a flat cornea, early-onset arcus lipoides, low anterior chamber depth, and an indistinct border between the sclera and cornea due to a decreased angle between the two. Although a small corneal diameter is anticipated, measuring it can be challenging because the scleral tissue overlaps the cornea by a few millimeters. In the patients who have been described, the anterior chamber depth has been found to vary from 0.8 to 2.1 mm. Moreover, high hyperopia, strabismus, microcornea, posterior embryotoxon, iridocorneal adhesions, iris lumps, iris wasting, and pupillary abnormalities can all be present. Instead of hyperopia, myopia has been ...
