Isolated Aniridia Patient Resource Guide

At a Glance

Isolated congenital aniridia is a rare genetic eye disorder, often caused by a PAX6 mutation, that affects the whole eye. Newly diagnosed patients require lifelong, specialized monitoring by a multidisciplinary team to manage complications like glaucoma, cataracts, and corneal issues.

Welcome to the Patient Resource Guide for Isolated Congenital Aniridia. This guide is designed to help parents, caregivers, and patients navigate the complex medical information following a new diagnosis. Aniridia is a rare genetic disorder that affects the entire eye and requires lifelong, specialized care.

Common questions in this guide

What is isolated congenital aniridia?
Isolated aniridia is a rare genetic disorder characterized by the partial or complete absence of the iris. It is a pan-ocular condition, meaning it affects the entire eye and requires lifelong specialized care.
How does aniridia affect the rest of the eye?
Aniridia affects more than just the iris. It can impact the cornea causing aniridia-associated keratopathy (AAK), the lens resulting in cataracts, the retina leading to foveal hypoplasia, and the eye's drainage system causing glaucoma.
Why is genetic testing important for a new aniridia diagnosis?
Genetic testing, specifically for the PAX6 gene, is crucial to understand the inheritance pattern. It is also vital for ruling out WAGR syndrome and determining the patient's risk for Wilms tumor, a type of childhood kidney cancer.
What do the Lagali Stage and Thomas Grade mean in aniridia?
Eye doctors use specific medical grading systems to monitor the condition over time. The Lagali Stage tracks the progression of corneal issues (AAK), while the Thomas Grade is used to assess foveal hypoplasia in the retina.
Who should be on a child's aniridia care team?
Your child will need a multidisciplinary care team coordinated by specialists. This typically includes a pediatric ophthalmologist, a geneticist, and specialized eye surgeons for treating complications like glaucoma or cataracts as they arise.
