Rieger's syndrome: (oligodontia and primary mesodermal dysgenesis of the iris) clinical features and report of an isolated case.J Pediatr Ophthalmol Strabismus. 1978 Mar-Apr; 15(2):67-70.JP
An 11-year-old female manifested bilateral prominent Schwalbe's line, iridal adhesions, displaced and irregular pupils. She had no evidence of juvenile glaucoma. The major nonocular finding in this patient was the congenital absence of her primary and permanent maxillary central and lateral incisors. Although missing or malformed teeth may occur in other conditions such as Down's syndrome, focal dermal hypoplasia syndrome, anhidrotic ectodermal dysplasia, chondroectodermal dysplasia, and incontinentia pigmenti, the clinician should include Rieger's syndrome in his differential diagnosis in patients with oligodontia in combination with malformation of the anterior chamber of the eye. Rieger's syndrome is a rare condition characterized by ocular and dental abnormalities, namely mesoectodermal dysgenesis of the iris and cornea of the eyes and hypodontia of the dentition. This report presents a sporadic case of Rieger's syndrome in an 11-year-old female and discusses the pertinent clinical features of this condition.
