What is Aniridia?
Aniridia is a rare genetic condition generally characterized by either the complete or partial absence of the iris, which is the colored part of the eye.
The word “aniridia” means “without iris”. The lack of iris is often the first and most noticeable feature of aniridia.
Aniridia can lead to complications with the eye including but not limited to:
- glaucoma
- cataracts
- corneal keratopathy
- strabismus
- nystagmus
- foveal hypoplasia
Aniridia and related complications present differently in each individual.
Recent research indicates that non-ocular conditions can also occur with aniridia. Some of these conditions include:
- central auditory processing disorder
- sleep disturbances
- brain abnormalities
- issues with the pancreas
Research is ongoing to better identify and understand these and other associated conditions.
