Bottom Line: However, there was no statistically significant difference compared to the non-surgical group during the first year.Within the surgical group, the higher baseline astigmatic subgroup and the 5- to 8-year-old group demonstrated greater cylinder reduction over time.The change in mean visual acuity was not significant in either group.

ABSTRACT

Purpose: To evaluate the effect of epiblepharon surgery on visual acuity and with-the-rule astigmatism in children compared to patients without surgical treatment.

Methods: We undertook a retrospective case control study and reviewed the charts of 202 eyes treated with epiblepharon surgery and of 142 eyes without surgery. The surgical procedure for epiblepharon correction used rotating suture techniques. Data regarding age, best corrected visual acuity, and degree of astigmatism were recorded. Baseline and 1-, 3-, 6-, and 12-month postoperative data were collected. The chi-square test, Student's t-test and general linear model analysis for repeated measures were applied.

Results: The mean astigmatism in the surgical group decreased from 1.10 ± 1.02 diopter (D) preoperatively to 0.84 ± 1.05 D at 3 months after surgery (p < 0.05). However, there was no statistically significant difference compared to the non-surgical group during the first year. The general linear model analysis comparing the mean astigmatism between the two groups over time showed a significant group-time interaction (p < 0.05). Within the surgical group, the higher baseline astigmatic subgroup and the 5- to 8-year-old group demonstrated greater cylinder reduction over time. The change in mean visual acuity was not significant in either group.

Conclusions: Significant astigmatic reduction was found after surgical correction in epiblepharon patients. Patients with higher baseline astigmatism exhibited greater astigmatic reduction after epiblepharon surgery. These results suggest that, in order to reduce astigmatism, an epiblepharon operation should be considered in patients with a high level of astigmatism.

Mean cylinder changes in subgroup A, B, and C over 1 year. Within the surgical group, the higher baseline astigmatic subgroup demonstrated greater cylinder reduction over time compared to the lower astigmatic subgroup at 1 year postoperative. *p<0.05; †Subgroup A, < 2 diopter (D); subgroup B, 2 to < 4 D; subgroup C, ≥ 4 D.

Figure 2: Mean cylinder changes in subgroup A, B, and C over 1 year. Within the surgical group, the higher baseline astigmatic subgroup demonstrated greater cylinder reduction over time compared to the lower astigmatic subgroup at 1 year postoperative. *p<0.05; †Subgroup A, < 2 diopter (D); subgroup B, 2 to < 4 D; subgroup C, ≥ 4 D.

Mentions: We also examined the association between astigmatic changes and initial cylinder values in both the surgical and non-surgical groups (subgroup A, B, and C) (Fig. 2). In the surgical group, there was a statistically significant decrease in astigmatism in subgroups B and C after 3 months postoper ative. In the non-surgical group, there were no significant astigmatic decreases for any initial astigmatism level. There was no association between baseline astigmatism and VA changes in either group.
