Abstract:
Objective To assess the tear film stability and morphological characteristics of the tarsal gland in myopic children.Methods In this prospective descriptive study,myopic children who performed refractive examinations in the Pediatric Ophthalmology & Refraction Clinic,Jinan Mingshui Eye Hospital from November 2021 to November 2022 were in-cluded.An Ocular Surface Disease Index(OSDI)questionnaire survey was carried out;tear meniscus height(TMH),non-invasive first breakup time(NIf-BUT)and images of the tarsal glands were obtained by OCULUS Keratograph 5M compre-hensive ocular surface analyzer.In addition,the atrophy and tortuosity of tarsal glands were scored to analyze the tear film stability and clinical characteristics of tarsal glands in myopic children.Results A total of 48 myopic children(91 eyes)aged from 7 to 16(10.25±2.23)years were recruited,including 27 males(56.25％)and 21 females(43.75％).The aver-age TMH was(0.19±0.04)mm(95％CI:0.18-0.19)and the average NIf-BUT was(5.40±2.62)s(95％CI:4.90-5.94);the TMH was positively correlated with NIf-BUT(r=0.223,P=0.034).The tarsal gland atrophy score was 1(0,1).The tortuosity score of the upper and lower tarsal gland was 0(0,1)and 0(0,0),respectively,with a statistically significant difference(Z=3.692,P＜0.001).In all subjects,49 eyes(53.85％)had tarsal gland atrophy,and 37 eyes(40.66％)had tarsal gland tortuosity.There were significant differences in TMH and NIf-BUT between children aged＜12 years and children aged ≥12 years(both P＜0.05).There was a significant difference in TMH between children with an OSDI score＜13 and children with an OSDI score ≥ 13(t=2.305,P=0.026).There was a significant difference in NIf-BUT between mild and moderate myopia children(t=2.300,P=0.024);the spherical equivalent was positively correlated with NIf-BUT(r=0.283,P=0.023).Conclusion Children with mild to moderate myopia show low tear film stability and a certain proportion of abnormal morphology in tarsal glands.In addition to the refractive status of children,attention should also be paid to ocular surface health in the refraction clinic.
