Background: Anterior segment dysgenesis (ASD) encompasses a range of congenital disorders affecting the development of the eye's anterior segment, often leading to significant visual impairment and glaucoma. Although numerous studies have focused on the genetic basis of ASD, few have comprehensively compared the clinical features across ASD subtypes. This study aims to address this gap by describing and comparing the clinical characteristics and ultrasound biomicroscopy (UBM) imaging features of various ASD subtypes in a Chinese tertiary medical center.

Introduction: Congenital aniridia is a rare panocular disorder that is associated with varying degrees of impairment of visual acuity. The COST Action (CA18116) developed a survey (aniridia-net.eu) to assess patient-reported experiences with congenital aniridia and its impacts on vision and daily life.

The Triple Procedure in Patients with Congenital Aniridia.

Chair and Clinical Department of Ophthalmology, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 65 Panewnicka Street, 40-760 Katowice, Poland.

Aniridia is a rare panocular, bilateral, and congenital disease characterized by complete or partial iris hypoplasia and foveal hypoplasia, leading to decreased visual acuity and nystagmus. AAK, also referred to as aniridic keratopathy, manifests as corneal surface damage, epithelial thinning or loss, inflammation with immune cell infiltration, vascularization, and chronic progressive opacification. Twenty-one eyes in eighteen patients with aniridia underwent the triple procedure for visual rehabilitation.

Article Synopsis
  • Congenital aniridia is a rare eye condition leading to iris absence, which often results in serious complications like blindness and glaucoma.
  • A study of 60 patients in China identified genetic mutations, mostly in the PAX6 gene, using advanced genetic analysis methods that revealed a 98.3% mutation detection rate.
  • The findings highlight the genetic diversity of aniridia within families and emphasize the importance of understanding these mutations for potential therapeutic approaches.

Objective: To examine the clinical phenotype and genetic deficiencies present in Chinese aniridia families with PAX6 haplotype deficiency.

Methods: A comprehensive questionnaire and ophthalmological assessments were administered to both affected patients and unaffected relatives. The clinical feature analysis included the evaluation of visual acuity, intraocular pressure, slit-lamp anterior segment examination, fundus photography, and spectral domain optical coherence tomography.
