Summary
Surgical overcorrection in esotropia is often reversible in patients with low hyperopia (≤2.5D) but not in those with higher hyperopia (>2.5D). This impacts long-term motor stability and sensory outcomes.
Area of Science:
- Ophthalmology
- Strabismus Surgery
- Pediatric Ophthalmology
Background:
- Partly accommodative esotropia requires surgical intervention.
- Surgical overcorrection can occur, necessitating further management.
- The impact of hyperopia levels on surgical outcomes is not fully understood.
Purpose of the Study:
- To evaluate long-term motor stability and sensory outcomes in patients with surgically overcorrected partly accommodative esotropia.
- To determine if hyperopia reduction influences these outcomes.
- To assess the role of pre-existing hyperopia in reversibility.
Main Methods:
- A 15-year prospective study with 5-year outcome analysis.
- Included 22 surgically overcorrected patients with partly accommodative esotropia.
- Control group of non-overcorrected patients used for comparison.
Main Results:
- Patients with ≤2.5D hyperopia had better motor alignment (7/8) compared to those with >2.5D hyperopia (4/14).
- Control patients with >2.5D hyperopia maintained alignment (91%) vs. study group (29%).
- Good stereopsis developed in 5/8 study patients with ≤2.5D hyperopia vs. 1/14 with >2.5D.
Conclusions:
- Postoperative reduction of hyperopic correction may not reverse surgical overcorrection in patients with >2.5D hyperopia.
- Reversibility is more likely in patients with ≤2.5D hyperopia.
- Hyperopia level is a critical factor in managing overcorrected partly accommodative esotropia.
