Summary
This study details a surgical technique for correcting vertical strabismus. Muscle transposition and realignment effectively treated both incyclotropia and excyclotropia in two patients.
Area of Science:
- Ophthalmology
- Strabismus Surgery
Background:
- Vertical strabismus, including incyclotropia and excyclotropia, presents complex surgical challenges.
- Accurate muscle positioning is crucial for successful strabismus correction.
Observation:
- A novel surgical approach involving transposition and realignment of vertical recti muscles was applied in two distinct cases.
- Case 1: Unilateral excyclotropia (11 degrees) resolved with nasal transposition of the inferior rectus muscle.
- Case 2: Induced excyclotropia was successfully reversed through horizontal realignment of superior recti muscles.
Findings:
- Nasal transposition of the inferior rectus muscle effectively corrected unilateral excyclotropia.
- Sequential nasal transposition and horizontal realignment of superior recti muscles provided a viable treatment for bilateral excyclotropia.
Implications:
- This surgical technique demonstrates versatility and efficacy in managing both incyclotropia and excyclotropia.
- The findings suggest a potentially valuable addition to the surgical armamentarium for vertical strabismus.
