Summary
Extraocular muscle surgery can restore binocular vision in patients with myasthenia gravis. This surgical approach offers a stable field of single vision, improving quality of life for those with persistent double vision.
Area of Science:
- Ophthalmology
- Neurology
Background:
- Myasthenia gravis often affects young adults, impacting their binocular vision and employment.
- While systemic treatments exist, persistent loss of binocularity can lead to chronic disability.
Observation:
- This study evaluated extraocular muscle surgery in five patients with stable myasthenia gravis and persistent diplopia.
- Patients presented with selective extraocular muscle involvement, including incomitant and concomitant squints, with muscle over- and underactions.
Findings:
- Conventional recession and resection procedures, augmented with Faden and adjustable sutures, were employed.
- All five patients achieved a larger, stable field of binocular single vision post-surgery.
Implications:
- Extraocular muscle surgery is a potentially beneficial treatment for selected myasthenia gravis patients with double vision.
- Surgical intervention can significantly improve visual function and quality of life in this patient group.
