Iridogoniodysgenesis, dominant type and variable expressivity. Treatment of glaucoma in iridogoniodysgenesis is primarily surgical. It is listed as a "rare disease" by the Office of Rare Diseases (ORD). This means that Iridogoniodysgenesis, dominant type, or a subtype of Iridogoniodysgenesis, dominant type, affects less than 200,000 people in the US population. This was first reported by Berg (1932). Iridogoniodysgenesis, dominant type Iridogoniodysgenesis, dominant type (type 1, IRID1) refers to a spectrum of diseases characterized by malformations of the irido-corneal angle of the anterior chamber of the eye. Iridogoniodysgenesis is the result of abnormal migration or terminal induction of neural crest cells. These cells lead
