Aniridia is a congenital, hereditary, bilateral, extreme form of iris hypoplasia that may be associated with other ocular defects.

Aniridia Day usually the same date as the solstice - a property of how high the sun is in the sky.

In 2020 the solstice has shifted to the 20th but we are keeping Aniridia Day on 21st June . This feature can range from a readily visible, almost complete absence of the iris, through enlargement and irregularity of the pupil mimicking a coloboma, to small slit-like defects in the anterior layer seen only on transillumination with a slit-lamp

Aniridia and associated conditions affect individuals differently. So while some affected people are partially sighted or blind, others may have near normal sight.
