Axenfeld-Rieger syndrome

Axenfeld-Rieger syndrome (RIEG) is a rare autosomal dominant disorder mainly affecting the anterior segment of the eyes congenitally. The ocular features include malformations of aniridia, coloboma of the iris, and ectopic pupils. Open-angle glaucoma can lead to blindness and is the main target of treatment in RIEG. Defects in other organ systems, typically the craniofacial, dental, and umbilical abnormalities, are also part of the disorder.
