Lisch epithelial corneal dystrophy (LECD), also known as band-shaped and whorled microcystic dystrophy of the corneal epithelium, is a rare form of corneal dystrophy first described in 1992 by Lisch et al. [1] In one study it was linked to chromosomal region Xp22.3, with as yet unknown candidate genes.
Lisch epithelial corneal dystrophy is characterized by feather shaped opacities and microcysts in the corneal epithelium that are arranged in a band-shaped and sometimes whorled pattern. Painless blurred vision sometimes begins after sixty years of life.

Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness. EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy , is a corneal epithelial disease that may result in recurrent corneal erosions , irregular corneal astigmatism , and decreased vision.
It has no systemic manifestations, unlike the other type of the dystrophy, Lattice corneal dystrophy type II. Lattice corneal dystrophy was first described by Swiss ophthalmologist Hugo Biber in 1890. [1] Lattice dystrophy gets its name from an accumulation of amyloid deposits, or abnormal protein fibers, throughout the middle and anterior stroma.
Posterior polymorphous corneal dystrophy (PPCD; sometimes also Schlichting dystrophy) is a type of corneal dystrophy, characterised by changes in Descemet's membrane and endothelial layer. Symptoms mainly consist of decreased vision due to corneal edema. In some cases they are present from birth, other patients are asymptomatic.
Thiel–Behnke dystrophy is a rare form of corneal dystrophy affecting the layer that supports corneal epithelium.The dystrophy was first described in 1967 [1] and initially suspected to denote the same entity as the earlier-described Reis-Bucklers dystrophy, but following a study in 1995 by Kuchle et al. the two look-alike dystrophies were deemed separate disorders.
Congenital stromal corneal dystrophy (CSCD) is an extremely rare, autosomal dominant form of corneal dystrophy. [1] Only 4 families have been reported to have the disease by 2009. [ 2 ] The main features of the disease are numerous opaque flaky or feathery areas of clouding in the stroma that multiply with age and eventually preclude visibility ...
