Summary
Rectus muscle transposition surgery effectively treats paralytic strabismus, reducing double vision and improving eye alignment. This surgical approach offers a valuable solution for complex horizontal and vertical eye movement disorders.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Ocular Motility Disorders
Background:
- Abducens palsy and Duane's syndrome are treated with rectus muscle transposition.
- Posterior fixation sutures augment surgical effectiveness.
Purpose of the Study:
- Summarize experience with full tendon rectus muscle transposition and a partial tendon transposition modification.
- Evaluate effectiveness for complex vertical and horizontal paralytic eye movement disorders.
Main Methods:
- Retrospective, noncomparative, interventional case series.
- Eighteen patients with paralytic strabismus underwent surgery.
- Procedures included full or three fourths partial tendon transposition with posterior fixation sutures.
Main Results:
- Primary position diplopia decreased from 64% to 14%.
- Anomalous head posture reduced from 56% to 6%.
- Primary position ocular alignment improved in all patients.
Conclusions:
- Full tendon rectus muscle transposition with posterior fixation sutures is effective.
- Vessel-sparing three fourths partial tendon transposition is also effective.
- Both techniques address complex paralytic ocular motility disorders.
