An abnormality of the cornea characterized by the deposition of calcium in a band across the central cornea, leading to decreased vision, foreign body sensation, and ocular irritation.

Congenital stromal corneal dystrophy is characterized by the presence of bilateral corneal opacities that can be seen at or shortly after birth. The surface of the cornea is normal or slightly irregular; small opacities are seen throughout the stroma of the entire cornea and give the cornea a cloudy appearance. Strabismus is common. Nystagmus is uncommon. Amblyopia can develop in children.

Lisch epithelial corneal dystrophy (LECD) is characterized by corneal bands of whorled, feathery, gray opacities of varying widths. The opaque bands consist of clear, densely crowded, intraepithelial blisters. Vision may be impaired if the bands involve the central cornea (Lisch et al., 1992; Lisch et al., 2000). Reviews Lisch and Weiss (2019) provided a clinical and genetic update of the corneal dystrophies. They noted that LECD shows slow progression, and may result in blurred vision if the pupillary axis is involved. Indirect illumination focusing on the corneal epithelium reveals crowded clear microcysts, which are the clinical hallmark of LECD.
