Insights
Preoperative hyperopia up to +5.0 diopters (D) did not impact surgical success for infantile esotropia. This suggests that surgical correction for esotropia is still viable in children with moderate hyperopia.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Strabismus Surgery
Background:
- Infantile esotropia is a common form of strabismus in young children.
- The role of preoperative hyperopia in surgical outcomes for infantile esotropia remains an area of investigation.
Purpose of the Study:
- To evaluate the relationship between preoperative hyperopia and surgical outcomes in patients younger than 24 months with infantile esotropia.
Main Methods:
- Retrospective review of medical records for patients undergoing bilateral medial rectus muscle recession.
- Patients were stratified into two groups based on preoperative hyperopia: < +3.0 D (Group I) and +3.0 to +5.0 D (Group II).
- Postoperative alignment was assessed at multiple time points up to 1 year, with yearly follow-up thereafter.
Main Results:
- Forty-six patients were analyzed (33 in Group I, 13 in Group II).
- Mean preoperative refractive errors were +0.88 D (Group I) and +3.45 D (Group II).
- No significant differences in surgical outcomes, success rates, or associated conditions (inferior oblique overaction, dissociated vertical deviation, re-operation rates) were observed between the groups.
Conclusions:
- Preoperative hyperopia of less than +5.0 D does not adversely affect the surgical outcomes of infantile esotropia.
- Surgical correction for esotropia should be considered even in the presence of moderate hyperopia, particularly when the esodeviation angle remains consistent after refractive correction.
Aim:
To evaluate the relation between preoperative hyperopia and surgical outcomes of infantile esotropia in patients younger than 24 months of age.
Methods:
Medical records of patients who underwent bilateral medial rectus muscle recession for infantile esotropia between November 1, 2002 and December 1, 2011 were retrospectively reviewed. Patients were divided into two groups according to the degree of preoperative hyperopia. Group I had less than +3.0 diopter (D) of hyperopia and group II had between +3.0 and +5.0 D of hyperopia. Postoperative alignments were evaluated 1wk, 3, 6mo, and 1y after surgery. Following the 1-year postoperative visit, patients were monitored yearly. Relationships between preoperative factors including hyperopia and postoperative outcomes were evaluated.
Results:
Forty-six patients were included, with 33 patients in group I and 13 patients in group II. The preoperative mean refractive error was +0.88 D in group I and +3.45 D in group II. Surgical outcomes were not significantly different between groups at any postoperative time point examined. Cumulative probability of surgical success, prevalence of inferior oblique overaction, dissociated vertical deviation, and re-operation rate were not significantly different between groups.
Conclusion:
Preoperative moderate hyperopia (less than +5.0 D) did not affect the surgical outcome of infantile esotropia. Therefore, the surgical correction of esotropia should be considered when the angle of esodeviation is unchanged following hyperopia correction, even in children with moderate hyperopia.
