This study introduces a new surgical method combining horizontal rectus muscle plication and vertical transposition for strabismus. The technique effectively corrected combined horizontal and vertical eye deviations in a small patient group.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Strabismus Correction
Background:
- Simultaneous correction of horizontal and vertical strabismus presents surgical challenges.
- Current methods often involve horizontal muscle transposition with recession and resection.
Purpose of the Study:
- To describe a novel surgical technique for correcting combined horizontal and vertical strabismus.
- To present initial results of this technique in a case series.
Main Methods:
- A novel surgical approach combining horizontal rectus muscle plication with vertical transposition was developed.
- The technique was applied to patients with combined horizontal and vertical strabismus.
Main Results:
- The described surgical technique successfully corrected both horizontal and vertical deviations.
- A small case series demonstrated the efficacy of the combined plication and transposition method.
Conclusions:
- Horizontal rectus muscle plication combined with vertical transposition is a viable technique for managing complex strabismus.
- This novel approach offers a new option for simultaneous correction of horizontal and vertical eye misalignments.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
