What is Aniridia Eye Disorder?

Nowadays, eye problem has become a common issue among masses at any age. Eyes issue not only occurs from watching too much TV or smartphones but also occurs genetically (aniridia). Here in this article, we are going to discuss the complete information about the Aniridia eye disorder.

Aniridia is explained as a genetic eye disorder that is rare and it is characterized by the one-sided or absolute iris absence. When there is a complete absence of iris then it is termed as ” aniridia” which is a non inheritable condition that has an impact on both eyes. The other names for the same disorder include:-

  • absent iris
  • irideremia
  • congenital aniridia

The colored part of the eye is the iris. Iris regulates the light amount which enters into the eye by controlling the pupil size and find out the color of a person’s eyes. The individuals who have light or blue eyes have irises that are less pigmented as compared to the masses who have dark-colored or brown eyes. Aniridia disorder can minimize visual acuity and surges the light sensitivity. If you have such an issue then you must approach eye hospital and consult your eye doctor.


Issues of Aniridia results in a little too intense development of the iris. In a few people, the underdeveloped iris is challenging observable to the untrained eye. The iris might be partly missing in some cases. Sometimes others may have complete iris absence. However, the masses who are having complete iris absence, some tissue of iris can normally be discovered during an eye examination under a microscope.

Symptoms and complications of these issues are as follows:-

  • Light sensitivity: An increased sensitivity and light aversion, which is also popularly known as photophobia, is experienced by some people. Because iris plays an important role in blocking and absorbing some amount of light that comes in the eye. A visual phenomenon called Glare is caused by brightness which extreme and uncontrolled may become a problem.
  • Glaucoma:  A rise in eye pressure due to the aniridia, results in glaucoma. This issue normally seems in late childhood to early immaturity. Glaucoma is often called the “sneak thief of sight” as it frequently goes undiscovered and grounds permanent eye damage.


Aniridia is a hereditary disorder. This issue is generated by a change in the PAX6 gene, which performs a pivotal role in the tissue and organ formation during embryonic development. These mutations can interrupt eye formation.


Aniridia issues are normally perceived at birth. One of the most perceptible features is that a baby is having very dark eyes with no actual iris color.


Sometimes, the underdeveloped iris is evident. To amend the eye appearance, the use of colored contact lenses or the opaque is preferred. To improve vision and reduces the sensitivity to light sensitivity then lenses will be considered one of the best options.
