Abstract

Purpose: Currently, no relevant studies have reported a relationship between astigmatism and peripheral refraction (PR). We aimed to describe the association between PR and relative peripheral refraction (RPR) with astigmatism in Chinese children with mild to moderate myopia, and to provide new insights into the influence of astigmatism.

Methods: Three-hundred-and-seven children (6-14 years old) from Shanghai were included in this study. The PR and RPR were measured using multispectral refraction topography (MRT). Cycloplegic refraction was measured using an autorefractor (KR-8900, Topcon), whereas axial length and ocular biological parameters were measured using Zeiss IOLMaster 700. Only data from the right eye were analyzed. Multivariate linear regression was used to explore the relationship between cylinder power and MRT parameters.

Results: Overall, the median spherical equivalent was -1.50 D (interquartile range, IQR: -2.25, -0.88), showing an apparent trend of hyperopic defocus from the macula to the peripheral retina. Astigmatism was correlated with PR rather than RPR especially at eccentrically inferior and within a 45° radius of the retina (coefficients 0.12-0.18, p < 0.05). Multivariate linear regression analysis demonstrated that the effect of astigmatism on PR tended to increase with greater lens thickness.

Conclusions: Astigmatism may be a risk factor for myopia due to its impact on peripheral refraction as opposed to relative peripheral refraction. In this cross-sectional study, we also found evidence supporting the association between peripheral hyperopia and myopia.

上海小学生近视周边屈光和相对周边屈光与散光的关系:一项横断面研究。
目的:目前还没有相关研究报道散光与外周屈光(PR)之间的关系。本研究旨在描述中国轻度至中度近视儿童的PR和相对外周屈光(RPR)与散光的关系,并为散光的影响提供新的见解。方法:选取上海市397名6 ~ 14岁儿童为研究对象。采用多光谱折射地形图(MRT)测量PR和RPR。使用自折射仪(KR-8900, Topcon)测量睫状体麻痹性屈光,使用蔡司IOLMaster 700测量眼轴长度和眼部生物学参数。只分析右眼的数据。采用多元线性回归方法探讨汽缸功率与MRT参数之间的关系。结果:总体而言,中位球等效为-1.50 D(四分位数范围,IQR: -2.25, -0.88),从黄斑到周围视网膜有明显的远视离焦趋势。结论:散光可能是近视的危险因素,因为散光对周围屈光的影响大于对周围屈光的影响,而不是对周围屈光的影响。在这项横断面研究中,我们还发现了支持周围性远视和近视之间关联的证据。

期刊介绍: Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
