Definition of Aniridia:

Aniridia is a rare genetic disorder characterized by the absence of the iris, which is the colored portion of the eye that surrounds the pupil. It is primarily caused by mutations in the PAX6 gene, which plays a crucial role in eye development.

Symptoms of Aniridia:

– Absence or severe hypoplasia (underdevelopment) of the iris

– Sensitivity to light (photophobia)

– Reduced visual acuity and blurry vision

– Nystagmus (involuntary eye movements)

– Cataracts

Treatment of Aniridia:

– There is no cure for aniridia, so treatment focuses on managing the symptoms and improving visual function:

– Corrective lenses or contact lenses can be prescribed to improve vision.

– Sunglasses or tinted lenses can help reduce light sensitivity.

– Surgical interventions like cataract removal or corneal transplantation may be required in some cases.

– Visual aids and assistive technologies can also be beneficial for individuals with aniridia.

Prognosis of Aniridia:

– The prognosis varies depending on the severity of aniridia and associated complications.

– Some individuals with aniridia may have near-normal vision with appropriate management, while others may experience significant visual impairment.

– Regular eye examinations and comprehensive vision care are crucial for managing the condition and preventing further complications.
