Aniridia associated with lens coloboma and secondary glaucoma treated with transcorneal argon laser ciliary body photocoagulation: a case report

Challenges in Surgical Intervention for a Rare Case of Anterior Segment Dysgenesis: A Case Report

Anterior Segment Dysgenesis (ASD) represents a spectrum of rare, congenital disorders that pose significant challenges to ophthalmological management due to their complex and heterogeneous nature. The management of ASD becomes particularly complex when associated with other serious ocular conditions. This report discusses the case of a 4-year-old girl diagnosed with ASD exhibiting a combination of sclerocornea, aphakia, aniridia, and secondary glaucoma. Owing to the complexity of such condition, a multi-disciplinary approach is required. Despite successful initial surgical interventions on the left eye, eye was lost due to subsequent endophthalmitis and retinal detachment, resulting in a decision to adopt a conservative, non-surgical approach for the right eye. Although a series of therapeutic interventions have been performed, the final visual outcome was poor, demonstrating the complexity and seriousness of such cases. This case serves as a reminder of the need for regular follow-up, prompt recognition, and management of potential complications. Further research is necessary to optimize the outcomes in patients with similar presentations.

Congenital aniridia - A comprehensive review of clinical features and therapeutic approaches

Congenital aniridia is a rare genetic eye disorder with total or partial absence of the iris from birth. In most cases the genetic origin of aniridia is a mutation in the PAX6 gene, leading to involvement of most eye structures. Hypoplasia of the fovea is usually present and is associated with reduced visual acuity and nystagmus. Aniridia-associated keratopathy, glaucoma, and cataract are serious and progressive complications that can further reduce visual function. Treatment of the ocular complications of aniridia is challenging and has a high risk of side effects. New approaches such as stem cell therapy may, however, offer better prognoses. We describe the various ocular manifestations of aniridia, with a special focus on conditions that commonly require treatment. We also review the growing literature reporting systemic manifestations of the disease.
