Early intervention for accommodative esotropia can maintain bifixation, improving ocular alignment and reducing the need for surgery. This supports timely treatment to prevent amblyopia and preserve binocular vision.

Area of Science:

  • Ophthalmology
  • Pediatric ophthalmology
  • Strabismus research

Background:

  • Accommodative esotropia is a common form of strabismus in children.
  • Maintaining binocular function is crucial for visual development.
  • Previous studies highlight the challenges in managing esotropia and preserving stereopsis.

Purpose of the Study:

  • To investigate the long-term outcomes of patients with accommodative esotropia.
  • To identify factors associated with the maintenance of bifixation.
  • To evaluate the impact of early alignment on surgical intervention and visual acuity.

Main Methods:

  • Retrospective analysis of 127 patient medical records with accommodative esotropia.
  • Inclusion criteria: within 10 prism diopters of orthophoria, with recorded stereopsis and binocular sensory tests.

  • Categorization based on bifixation (stereopsis ≥ 50 arc seconds) versus monofixation.

    • Main Results:

    • Bifixation was achieved in 24% of patients (n=31) over an average follow-up of 89 months.
    • Monofixation was present in 76% (n=96) over an average follow-up of 84 months.
    • Patients with bifixation had lower rates of constant esotropia, better initial alignment, and less need for bifocals or surgery.

    Conclusions:

    • Maintenance of bifixation is achievable in accommodative esotropia with timely ocular alignment.
    • Early therapeutic intervention can prevent amblyopia and deterioration of ocular alignment.
    • Preserving bifixation is associated with significantly better long-term visual outcomes.
