Summary
Oblique muscle surgery effectively treats bilateral trochlear paresis, alleviating eye deviations. Specific surgical approaches, like superior oblique tuck and inferior oblique recession, are tailored to patient
Area of Science:
- Ophthalmology
- Strabismus Surgery
Context:
- Bilateral trochlear paresis presents complex strabismic deviations.
- Surgical management often involves oblique muscles.
Purpose:
- To evaluate the efficacy of superior oblique tuck and inferior oblique recession in patients with bilateral trochlear paresis.
- To determine optimal surgical strategies based on preoperative deviation magnitudes.
Summary:
- Fifteen patients with bilateral trochlear paresis underwent oblique muscle surgery, with 12 receiving combined superior oblique tuck and inferior oblique recession, and 3 receiving superior oblique tuck alone.
- Surgery successfully alleviated excyclotropia and vertical deviations in most cases, with minimal decrease in effect over time.
- Specific criteria, including excyclotropia and vertical deviation in primary position, guided the choice between single or combined oblique muscle procedures.
Impact:
- Surgical interventions can significantly improve binocular vision and alleviate symptoms associated with bilateral trochlear paresis.
- The study provides evidence-based guidelines for selecting surgical techniques in managing complex strabismus.
- Successful outcomes suggest oblique muscle surgery is a viable option for correcting significant deviations in bilateral trochlear palsy.
