Asymmetrical Corneal Topography in Map-Dot-Fingerprint Dystrophy Resembling Keratoconus

Abstract

Map-dot-fingerprint dystrophy cause painless blurred vision due to irregular astigmatism. Corneal topography may show asymmetry and irregularity and can resemble keratoconus. Two patients with map-dot dystrophy with unilateral blurring of vision are presented that were misdiagnosed as keratoconus due to asymmetric corneal topography. Medical treatment with hypertonic saline and lubrication in one patient and alcohol assisted epithelial delamination in the second patient restored visual acuity and restored normal appearance of corneal topography.
