Late-onset Fuchs endothelial corneal dystrophy (FECD) is a degenerative disorder affecting roughly 4% of the population older than 40 years. It is distinguished from other corneal disorders by the progressive formation of guttae, which are microscopic refractile excrescences of the Descemet membrane, a collagen-rich basal lamina secreted by the corneal endothelium. From onset, it usually takes 2 decades for FECD to impair endothelial cell function seriously, leading to stromal edema and impaired vision (Sundin et al., 2006).For a discussion of genetic heterogeneity of Fuchs endothelial corneal dystrophy, see FECD1 (OMIM ).

Fuchs endothelial corneal dystrophy (FECD) is the most common genetic disorder of the corneal endothelium. Late-onset FECD is marked by thickening of Descemets membrane and excrescences, called guttae, that typically appear in the fourth or fifth decade. Disease progression results in decreased visual acuity as a result of increasing corneal edema, and end-stage disease is marked by painful epithelial bullae (summary by Riazuddin et al., 2013).For a discussion of genetic heterogeneity of Fuchs endothelial corneal dystrophy, see FECD1 (OMIM ).

Lacrimoauriculodentodigital (LADD) syndrome is a multiple congenital anomaly syndrome characterized by hypoplasia, aplasia or atresia of the lacrimal system; anomalies of the ears and hearing loss; hypoplasias, apalsias or atresias of the salivary glands; dental anomalies and digital malformations.

Xeroderma pigmentosum is a genetically heterogeneous condition characterized by increased sensitivity to ultraviolet (UV) irradiation and increased risk of skin cancer resulting from a defect in DNA repair. XPC is the most common form of XP in the white population, accounting for over a third of all cases in this group (review by Li et al., 1993).For a general discussion of xeroderma pigmentosum, see XPA (OMIM ).

Immunodeficiency due to a classical component pathway complement deficiency is a primary immunodeficiency due to a deficiency in either complement components C1q, C1r, C1s, C2 or C4 characterized by increased susceptibility to bacterial infections, particularly with encapsulated bacteria, and increased risk for autoimmune disease. Most commonly, these include systemic lupus erythematosus (SLE), SLE-like disease, Henoch-Schonlein purpura, polymyositis and arthralgia. Disease severity is variable and dependent on the complement affected.

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 guttae), generalized corneal edema, with gradually decreased visual acuity.
