Study Notes
Treatments for Intermittent Exotropia (IXT)
- Surgical treatments include unilateral recession/resection (R&R) and bilateral lateral rectus recession (BLR).
- In R&R, the lateral rectus (LR) muscle is weakened while the medial rectus (MR) muscle is strengthened.
- In BLR, the LR muscle is weakened in both eyes.
- No statistically significant difference in outcomes between unilateral R&R and BLR techniques.
Surgical Outcomes and Recurrence
- Recurrence rate within two years is approximately 21% based on retrospective studies.
- A cohort study found that 8% of patients needed a second operation within six months after the initial surgery.
- Additional 21% experienced overcorrection after six months of follow-up.
Non-Surgical Treatments
- Watchful waiting is an approach for managing IXT without immediate intervention.
- Occlusion therapy involves part-time patching as a treatment method.
- Over-minus lens correction is applied for specific types of IXT.
- Prism therapy is used to manage symptoms.
- Vision therapy aims to improve visual processing and control.
