Fuchs endothelial corneal dystrophy FECD is the most frequent form of posterior corneal dystrophy see this term and is characterized by excrescences on a thickened Descemet membrane corneal guttaegeneralized corneal edema, with gradually decreased visual acuity. The exact prevalence is not known but extreme geographical variability has been reported. The condition is more common and more severe in women sex ratio Patients with FECD are initially asymptomatic.

Clinical onset is generally in the 5th or 6th decade of life. Discomfort and painful episodes of recurrent corneal erosions occur, along with gradually developing opacification leading to hazy vision.

Over time, discomfort may diminish but severe impairment of visual acuity, and even blindness in elderly patients, may be observed.

Fuchs’ corneal dystrophy

The clinical course often spans 10 to 20 years. The condition is often associated with cataracts. Microbial keratitis and corneal neovascularization are extremely rare complications.

Stromal edema produces a blue-gray haze anterior to Descemet membrane followed by eventual thickening of the entire corneal stroma and development of a ground-glass corneal appearance.

The etiology of FECD is unknown, but it seems to be a heterogenous complex inherited disorder caused by the interaction of genetic and environmental factors. Mutations ditrofia certain genes have been reported in some cases of FECD.

Rare cases of early onset have been related to cornneal in the COL8A2 gene 1p Other cases have been mapped to chromosomes 13 13pter-3q Although most patients with FECD lack a positive family history, blood relatives sometimes manifest corneal guttae.

FECD may also affect siblings and two or more successive generations, apparently as an autosomal dominant disorder having incomplete penetrance, but a simple autosomal dominant pattern is unlikely.
