Summary
Patients with basic intermittent exotropia and unequal accommodative response showed better outcomes with recession-resection surgery. Asymmetric accommodation may predict exotropia surgery success.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Binocular Vision
Background:
- Basic intermittent exotropia is a common strabismus condition.
- Surgical outcomes can vary, and predicting factors are crucial for treatment planning.
Purpose of the Study:
- To assess accommodative response symmetry in patients with basic intermittent exotropia.
- To determine if accommodative response predicts surgical outcomes for unilateral recession-resection or symmetric lateral rectus recession procedures.
Main Methods:
- Dynamic retinoscopy and the monocular estimate method were used preoperatively in 47 patients.
- Patients were grouped based on equal or unequal accommodative response between eyes.
- Surgical procedures included unilateral recession-resection or symmetric lateral rectus recessions.
Main Results:
- 68% of patients exhibited asymmetric accommodation (≥0.75 D interocular difference).
- Patients with unequal accommodation had better outcomes with recession-resection (72%) than lateral rectus recessions (35.7%).
- Patients with equal accommodation showed similar outcomes regardless of surgical approach (87% vs. 71%).
Conclusions:
- Recession-resection procedures appear more beneficial for patients with asymmetric accommodative response.
- Decreased accommodative response in the nondominant eye may indicate a favorable outcome for exotropia surgery.
