Long-term Motor and Sensory Outcomes After Unilateral Lateral Rectus Recession-Medial Rectus Resection for Infantile...

Area of Science:

• Ophthalmology
• Strabismus Surgery
• Pediatric Ophthalmology

Background:

• Infantile constant exotropia is a significant cause of visual impairment in children.
• Surgical correction, such as unilateral lateral rectus recession-medial rectus resection, aims to improve ocular alignment and visual function.
• Long-term outcomes regarding both motor alignment and sensory fusion are crucial for evaluating surgical success.

Purpose of the Study:

• To evaluate the long-term motor and sensory results of unilateral lateral rectus recession-medial rectus resection in patients with infantile constant exotropia.
• To identify factors influencing surgical success and long-term visual outcomes.

Main Methods:

• Retrospective review of medical records for patients with infantile constant exotropia.
• Unilateral lateral rectus recession-medial rectus resection performed as the primary surgical intervention.
• Minimum postoperative follow-up period of 4 years to assess long-term outcomes.

Main Results:

• Overall surgical success (motor alignment) was achieved in 60% of the 20 patients studied.
• Peripheral binocular single vision was achieved in 25% of patients; stereopsis was not achieved in any.
• Factors such as age at surgery, strabismus duration, and preoperative deviation angle did not predict motor or sensory outcomes.

Conclusions:

• Unilateral recession-resection provides successful long-term motor alignment in 60% of infantile constant exotropia cases.
• While peripheral binocular vision is achievable, stereopsis remains a challenge.
• Surgical timing and disease duration do not appear to influence the long-term motor and sensory results.
