[Congenital aniridia in children]

Area of Science:

• Ophthalmology
• Genetics
• Pediatrics

Background:

• Congenital aniridia is a rare genetic disorder affecting the entire eye, characterized by partial or complete iris absence.
• Clinical manifestations in children include significant photophobia and nystagmus.
• The condition's prevalence ranges from 1:40,000 to 1:100,000 births, potentially underestimated.

Purpose of the Study:

• To summarize the key aspects of congenital aniridia in children.
• To highlight associated systemic disorders and their implications.
• To emphasize the importance of early diagnosis and comprehensive management.

Main Methods:

• Review of existing literature on congenital aniridia.
• Analysis of clinical signs, prevalence, and associated syndromes.
• Discussion of diagnostic approaches and therapeutic strategies.

Main Results:

• Congenital aniridia presents with ocular abnormalities including foveal hypoplasia, glaucoma, cataracts, and corneal opacification.
• Associated syndromes like WAGR syndrome (Wilms' tumor, aniridia, genitourinary anomalies, mental retardation) and Gillespie syndrome require rapid detection.
• The disease frequently leads to severe visual impairment or blindness, necessitating UV protection and optical correction.

Conclusions:

• Prompt diagnosis and management of congenital aniridia and its associated conditions are essential.
• Comprehensive ocular treatment and UV protection are critical for visual preservation.
• Ongoing clinical research in corneal stem cells and gene therapy offers future treatment possibilities.
