Summary

Strabismus is common in bilateral Peters anomaly, often linked to vision asymmetry. Early amblyopia therapy is crucial for visual rehabilitation in these patients.

Area of Science:

  • Ophthalmology
  • Genetics
  • Developmental Biology

Background:

  • Peters anomaly is a rare anterior segment dysgenesis.
  • Characterized by abnormal anterior chamber cleavage during gestation.
  • Affects ocular development and visual potential.

Purpose of the Study:

  • Examine strabismus and amblyopia prevalence in bilateral Peters anomaly.
  • Identify predictive factors for strabismus development.
  • Analyze visual outcomes and associated anomalies.

Main Methods:

  • Retrospective review of 25 patients with bilateral Peters anomaly (1995-2005).
  • Recorded ocular/systemic anomalies, amblyopia therapy, visual acuity, and alignment.
  • Used Fisher's exact test to assess predictive factors for strabismus.

Main Results:

  • 72% of patients developed strabismus; asymmetric vision was a significant predictor (P=0.002).
  • Final visual acuity varied widely; amblyopia treatment improved vision in 3/5 patients.
  • Esotropia and exotropia were common forms of strabismus.

Conclusions:

  • Strabismus is frequent in bilateral Peters anomaly.
  • Asymmetric vision, structural anomalies, and amblyopia are predisposing factors.
  • Aggressive amblyopia therapy is recommended for visual rehabilitation.
