Aniridia, a severe eye condition, often presents with multiple complications and delayed diagnosis in our region. Early intervention and adapted surgical techniques are crucial for improving visual outcomes in aniridia patients.

Area of Science:

  • Ophthalmology
  • Genetics
  • Pediatric Medicine

Background:

  • Aniridia, a rare congenital absence of the iris, presents significant challenges in ocular development and function.
  • This report details five cases of aniridia diagnosed over five years, highlighting associated ocular and systemic abnormalities.

Observation:

  • A cohort of five patients (2 adults, 3 children) aged 8-45 years with aniridia were analyzed.
  • Associated conditions included lens ectopy, ptosis, microcornea, macular hypoplasia, and pectus excavatum.
  • Common complications observed were corneal dystrophy, lens opacities, elevated intraocular pressure (IOP), and severe amblyopia.

Findings:

  • Four out of five aniridia patients presented with additional congenital abnormalities.
  • All patients experienced ocular complications, with lens opacities and amblyopia being highly prevalent.

  • Glaucoma management involved IOP-lowering medications, successfully normalizing pressure in affected individuals.

    • Implications:

    • Late diagnosis and presentation with complications, including amblyopia, complicate aniridia management.
    • Surgical intervention for glaucoma in aniridia requires careful consideration and is not always the primary approach.
    • Genetic counseling, early diagnosis, and tailored surgical strategies are essential for optimizing visual prognosis in aniridia.
