Unilateral Surgery in Bilateral Asymmetrical Dissociated Vertical Deviation With Strong Preferential Fixation
Journal of Pediatric Ophthalmology and Strabismus
|October 1, 2021
Summary
Unilateral surgery for dissociated vertical deviation (DVD) in the non-dominant eye effectively improved the condition without negatively impacting the dominant eye. This approach is a safe and effective treatment option for DVD.
Area of Science:
- Ophthalmology
- Strabismus Surgery
Background:
- Dissociated vertical deviation (DVD) is a common strabismus anomaly.
- Optimal surgical management for DVD, particularly in conjunction with other deviations like congenital esotropia, remains a subject of investigation.
Purpose of the Study:
- To evaluate the efficacy and safety of unilateral surgery for treating dissociated vertical deviation (DVD).
- To assess the impact of unilateral DVD surgery on the non-operated (dominant) eye.
Main Methods:
- A cohort of 14 patients with congenital esotropia and DVD underwent bilateral medial rectus recession.
- Unilateral surgery for DVD was performed on the non-dominant eye, specifically in cases without a significant postoperative dominance switch.
Main Results:
- All patients demonstrated significant improvement in DVD in the primary gaze position following unilateral surgery.
- No adverse effects, such as hypotropia, anti-elevation syndrome, or inferior oblique overaction, were observed in the contralateral (dominant) eye.
Conclusions:
- Unilateral surgery for DVD in the non-dominant eye is a safe and effective treatment.
- This surgical approach does not induce manifest DVD in the previously unoperated dominant eye, even with strong fixation preference.
