Anterior Segment Dysgenesis 7; Asgd7

Description

Anterior segment dysgeneses (ASGD or ASMD) are a heterogeneous group of developmental disorders affecting the anterior segment of the eye, including the cornea, iris, lens, trabecular meshwork, and Schlemm canal. The clinical features of ASGD include iris hypoplasia, an enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, an abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface (summary by Cheong et al., 2016).In sclerocornea there is congenital, nonprogressive corneal opacification that may be peripheral, sectoral, or central in location. Visual prognosis is related to the central corneal involvement. The cornea has a flat curvature. The majority of cases are bilateral (summary by Smith and Traboulsi, 2012).Isolated sclerocornea is caused by displacement of the limbal arcades and may be associated with cornea plana; in this condition, the anterior chamber is visible and the eye is not microphthalmic. In complex sclerocornea, however, corneal opacification is associated with microphthalmia, cataract, and/or infantile glaucoma. The central cornea is usually relatively clear, but the thickness is normal or increased, never reduced (summary by Nischal, 2007).
