Pupillary-iris-lens membrane with goniodysgenesis: a case report

We describe a rare case of pupillary-iris-lens membrane with goniodysgenesis, a unilateral neurocristopathy. The membrane represents ectopic iris on the lens with abnormal iris stroma and anterior chamber angle from aberrant induction, migration or regression of neural crest cells. The membrane can be progressive. Catastrophic vision loss from angle closure can occur and may be controlled with surgery. This subject needed treatment for amblyopia.
