Axenfeld-Rieger Anomaly, Plus

Clinical Characteristics
Ocular Features: 

This rare disorder has ocular features of Rieger anomaly with significant systemic features but different than those found in the Axenfeld-Rieger syndrome.  The iris is hypoplastic and the pupil may be distorted secondary to anterior synechiae.  Schwalbe line is prominent.  There are no reports of glaucoma but this may be biased by the small number of patients reported.  Hypertelorism, prominent eyes and strabismus have been described.  Several patients have had absence of the extraocular muscles.

Systemic Features: 

Hypotonia, lax joints, midface hypoplasia, prominent forehead, and short stature have been described.  Some, but not all patients have a degree of psychomotor retardation.  Mild hearing impairment has been reported.


This is likely an autosomal dominant disorder in which mutations of the PITX2 and FOXC1 genes common in Axenfeld-Rieger syndrome have been ruled out.  No locus has been identified.

Autosomal dominant
Treatment Options: 

No treatment is available.
