Summary
Extraocular muscle surgery effectively treats thyroid-associated ophthalmopathy (TAO) by releasing muscle restrictions and improving eye alignment. This surgical intervention restores binocular vision and is best performed when TAO is stable for 4-6 months.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Endocrinology
Context:
- Thyroid-associated ophthalmopathy (TAO) often causes restrictive strabismus.
- Fibrosis of extraocular muscles leads to limited eye movement and diplopia.
- Surgical intervention aims to restore ocular alignment and function.
Purpose:
- To evaluate the indications, surgical methods, and outcomes of extraocular muscle surgery in TAO patients.
- To assess the efficacy of surgery in improving ocular motility and binocular vision.
- To determine the optimal timing for surgical intervention in TAO.
Summary:
- Extraocular muscle surgery, primarily recession, was performed on 11 TAO patients to address fibrotic muscle restrictions.
- Postoperatively, patients showed improved ocular alignment and movement, with 9 out of 11 achieving restored binocular vision.
- Follow-up at 2 months indicated sustained alignment improvements.
Impact:
- Extraocular muscle surgery is a valuable functional rehabilitation for TAO.
- Diplopia and restricted ocular movements are key indications for surgical consideration.
- Optimal surgical timing, 4-6 months after disease stabilization, under local anesthesia, ensures excellent results.
