Definition:

Peters anomaly is a subtype of anterior segment dysgenesis. It is a developmental disorder that presents with central corneal opacity (leukoma), iris and lenticular adhesions to the cornea, and lack of the posterior corneal stroma, and Descemets membrane. Approximately half of patients develop glaucoma. The majority of cases are sporadic; however, autosomal recessive and dominant patterns of inheritance have been found. Peters-plus syndrome is a rare autosomal recessive genetic disorder including ocular features, systemic malformations, and variable degree of developmental delay. It is caused by mutations in B3GALTL gene.
