Abstract
BACKGROUND To investigate the prevalence and risk factors for astigmatism in 7-19-year-old students in Xinjiang, China. METHODS A school-based, cross-sectional study was conducted on students who underwent refraction examination in Xinjiang, China, between May and December 2019. The prevalence of astigmatism was determined. Astigmatism was defined as cylinder power (C) ≤-0.75 D, undefined astigmatism as ≤-1.50 D, and high astigmatism as C ≤-3.00 D. Astigmatism types were: against-the-rule astigmatism (maximum refraction of the main meridian in 180° ± 30°), with-the-rule astigmatism (maximum refraction of the main meridian at 90°±30°), and oblique astigmatism (all other cases). RESULTS Of the 71,838 students examined (51.0% boys, 7 - 19 years old), 25,945 (36.1%, 95%CI: 35.52-36.68%) had astigmatism and 1267 (1.8%, 95%CI: 1.07-2.53%) had high astigmatism. The prevalence of astigmatism was greater in Han individuals (39.6%) compared with the Hui (34.0%), Kazakh (34.0%), Kyrgyz (32.1%), and Uyghur (26.4%) populations. Among the 25,945 students with astigmatism, 19,947 had with-the-rule astigmatism (76.9%), 3405 had against-the-rule astigmatism (13.1%), and 2593 had oblique astigmatism (10.0%). Multivariable logistic regression analysis showed that ethnicity (Han individuals more susceptible), male gender, age, and refractive errors (myopia and hyperopia) were independently associated with astigmatism, high astigmatism, and with-the-rule astigmatism (all P < 0.05). CONCLUSIONS The prevalence of astigmatism among children and adolescents in Xinjiang was 36.1%, including 1.8% of high astigmatism. In this population, astigmatism was mainly of the with-the-rule astigmatism type (76.9%). Han ethnicity, male gender, and myopia or hyperopia were independently associated with a high risk of astigmatism.

Abstract
PURPOSE To investigate the effect of epiblepharon surgery on motor and sensory function in children with epiblepharon and concomitant strabismus. METHODS Among 564 patients who underwent epiblepharon correction surgery from May 2016 to April 2023, 45 children who were examined for strabismus were included in the study. Preoperative and postoperative visual acuity, refraction, and angle of deviation were analyzed. For those with significant angle of deviation, additional stereopsis, sensory fusion, and returning time were retrospectively investigated. The angle of deviation was examined by one examiner at distance and near. RESULTS The mean age of 45 children (18 boys and 27 girls) was 6.8 ± 2.9 years. Fifteen had significant strabismus at the time of epiblepharon surgery. Visual acuity improved in both the total and strabismus groups. Improvement in stereopsis and fusion was also observed in the strabismus group. The angle of deviation showed no difference in both groups. CONCLUSIONS Epiblepharon could affect ocular manifestations of strabismus as shown in this study. The authors suggest strabismus treatment be continued after epiblepharon surgery, with improved sensory function. Further evaluation with larger groups is needed in the future.

Abstract
BACKGROUND To evaluate the clinical efficacy of combined minimal lower eyelid epicanthoplasty and thermal contraction for epiblepharon repair in Chinese children. METHODS Between January 2017 and August 2020, a single surgeon corrected epiblepharon in Chinese children using minimal lower eyelid epicanthoplasty combined with thermal contraction. First, a minimal epicanthoplasty flap to balance the lower eyelid was made cross the lower eyelid epicanthus, which connected with a 20-mm-long incision 1.5 mm below the lower eyelid margin. After removing the hypertrophic orbicularis oculi muscle running between the lower epicanthal fold and the medial canthal tendon, thermal cauterization was applied to increase lower eyelid rotation by creating adhesions between the lower eyelid retractor and tarsus. The residual medial edge was sutured to the corner of the epicanthus to decrease the lower eyelid epicanthus. The postoperative follow-up ranged from 3 to 24 months. We retrospectively analyzed cases to determine whether this approach decreased the lower eyelid epicanthal fold to equalize the tension of the lower eyelid. The surgical outcomes including the direction of lower eyelid eyelashes, complications, and refractive errors were evaluated. RESULTS Data from each eye of 53 Chinese children (29 female, 24 males; mean age: 5.3 ± 2.3 years) who had undergone minimal lower eyelid epicanthoplasty combined with thermal contraction were included. During follow-up, recurrence was observed in just one of the 106 eyes (0.94%), and two eyes (1.89%) showed under-correction. No visible scars formed in the postoperative period. All patients' parents were satisfied with the cosmetic results and had no serious complaints. The mean astigmatism was significantly reduced by the surgery from 1.82 ± 0.45 diopters (D) preoperatively to 1.43 ± 0.36 D postoperatively (P < 0.05). CONCLUSION This surgery is easy to design, time-efficient, and is effective in the correction of epiblepharon. The procedure allows surgeons to achieve good appearance and natural eyelid contour without apparent complications.

Abstract
PURPOSE The study aims to examine an incidence and risk factors of severe corneal involvement in patients with congenital lower eyelid epiblepharon. METHODS This retrospective, observational study included 509 patients (933 eyes) with congenital lower eyelid epiblepharon. Data on age, sex, affected side, past history, past surgery, presence or absence of concomitant periocular/ocular diseases, body height and weight, astigmatic power, and corneal involvement were collected. Severe corneal involvement included corneal scarring, vascularization, and perforation. RESULTS Severe corneal involvement was found in 30 patients (5.9%) (34 eyes, 3.6%). Corneal scarring and perforation with scarring were shown in 29 patients (33 eyes) and 1 patient (1 eye), respectively. Nine patients (12 eyes) demonstrated concomitant corneal vascularization with corneal scarring. Logistic regression analysis showed that body mass index had an odds ratio of 1.057 (P = 0.078). Age and sex did not affect occurrence of severe corneal involvement (P > 0.050). CONCLUSIONS In this study, 5.9% of patients showed severe corneal involvement in congenital lower eyelid epiblepharon. Logistic regression analysis indicates that a high body mass index was a possible risk factor of severe corneal involvement caused by congenital lower eyelid epiblepharon.

Abstract
Obesity has been regarded as a risk factor for several ocular diseases. This study aims to investigate the age- and sex-specific relationship between epiblepharon and obesity in children. A retrospective case-control study was conducted using the Chang Gung Research Database. Children ≤ 18 years of age with epiblepharon were identified from 1 January 2009 to 31 December 2019. Children were classified into three groups: normal, overweight and obese groups. A total of 513 patients and 1026 controls (57.7% males) aged 1 to 18 matched by sex and age were included in the analysis. The median body mass index (BMI) of children with epiblepharon was significantly higher than that of children without epiblepharon (p < 0.001). In the subgroup analysis, among boys aged 4 to 9 years, the BMI in boys with epiblepharon was significantly higher than that in boys without epiblepharon (p < 0.05) and the risk of epiblepahron in overweight/obese boys was significantly higher than in non-overweight boys (OR = 1.74, 95% CI = 1.07-2.82 for age 4 to 6; OR = 3.06, 95% CI = 1.56-6.03 for age 7 to 9). On the other hand, among girls aged 13 to 18 years, the BMI in adolescent girls with epiblepharon was significantly higher than that in the control group (p < 0.05) and overweight/obese girls had a statistically higher risk of persistent epiblepharon than non-overweight girls (OR = 3.70, 95% CI = 1.38-9.97). The association between obesity and epiblepharon varies in strength according to age in a sex-specific manner.

Abstract
BACKGROUND Children with congenital glaucoma are often accompanied by acquired epiblepharon in the lower eyelid, which causes entropion of the lower eyelid and damages the cornea.
AIM To infer the possible causes of lower eyelid entropion by comparing the difference of ocular axis and corneal diameter between inverted and non-inverted ciliary eyes in children with congenital glaucoma.
METHODS A total of 15 patients (11 males and 4 females) diagnosed with congenital glaucoma between July 2016 and January 2019 at Tongren Hospital were included. Five patients had bilateral glaucoma, and ten had unilateral glaucoma. Each patient had only one eye with lower eyelid entropion which is associated with congenital glaucoma. All the patients had no entropion in another eye. The clinical data were collected. Main outcome measures were the ocular axis and corneal diameter.
RESULTS The average age of the 15 patients was 1.85 ± 0.49 years. Paired t-test showed that the average ocular axis of congenital glaucoma eyes with lower eyelid entropion (24.86 ± 3.44 mm) was significantly longer than that of congenital glaucoma eyes without lower eyelid entropion (20.79 ± 1.34 mm; P < 0.001). The average corneal diameter of congenital glaucoma eyes with lower eyelid entropion (13.61 ± 0.88 mm) was also significantly greater than that of congenital glaucoma eyes without lower eyelid entropion (11.63 ± 0.48; P < 0.001).
CONCLUSION The rapid growth of the ocular axis and corneal diameter may be the main cause of congenital glaucoma with acquired lower eyelid entropion. Therefore, children with poor control of intraocular pressure and excessive growth of ocular axis and corneal diameter must be observed for the existence of acquired epiblepharon.
