Abstract

Purpose: We measured objective cyclodeviation in patients aged 10-90 years and evaluated differences between age groups, sexes, and eye sides using the disc-fovea angle (DFA).

Study design: Retrospective observational study METHODS: Patients who underwent fundus photography at Kozawa Eye Hospital and Diabetes Center between January 2016 and August 2021 were included. The participants aged 10-90 years were allocated into 10-year age groups. Each age group comprised 400 eyes from 200 participants (100 male and 100 female participants), resulting in a total of 3,600 eyes from 1,800 participants. DFA, defined as the angle between a horizontal line passing through the macula and the line joining the central fossa and papillary center, was analyzed using the Angle Tool in ImageJ software. When the horizontal line passing through the macula was higher than the line joining the central fossa and papillary center, the eye was classified as having excyclotorsion, indicated by a positive sign.

Results: DFA increased with age, from 6.37 ± 3.56° in participants in their 10s to 8.46 ± 3.96° in those in their 90s (p < 0.0001). DFA was significantly different between sexes (male vs. female: 7.25 ± 3.60° vs. 7.65 ± 3.71°; p < 0.0001). Additionally, a significant difference was observed between eye sides (right vs. left eye: 7.13 ± 3.69° vs. 7.77 ± 3.60°; p < 0.0001).

Conclusion: DFA increases with age, exhibits higher values in female individuals, and shows greater measurements in the left eye.

根据年龄、性别和眼侧评价客观眼环偏差。
目的:我们测量了10-90岁患者的客观环偏,并利用椎间盘-中央凹角(DFA)评估不同年龄组、性别和眼侧的差异。研究设计:回顾性观察性研究方法:纳入2016年1月至2021年8月在Kozawa眼科医院和糖尿病中心接受眼底摄影的患者。年龄在10-90岁之间的参与者被分为10岁年龄组。每个年龄组由200名参与者(100名男性和100名女性)的400只眼睛组成,总共有1800名参与者的3600只眼睛。DFA定义为穿过黄斑的水平线与中央窝与乳突中心连接线之间的夹角,使用ImageJ软件中的角度工具进行分析。当穿过黄斑的水平线高于中央窝与乳突中心的连线时,诊断为外扭转,为阳性。结果:DFA随年龄增加,从10多岁时的6.37±3.56°增加到90多岁时的8.46±3.96°(p)结论:DFA随年龄增加,在女性个体中表现出更高的值,且在左眼测量值更大。

期刊介绍: The Japanese Journal of Ophthalmology (JJO) was inaugurated in 1957 as a quarterly journal published in English by the Ophthalmology Department of the University of Tokyo, with the aim of disseminating the achievements of Japanese ophthalmologists worldwide. JJO remains the only Japanese ophthalmology journal published in English. In 1997, the Japanese Ophthalmological Society assumed the responsibility for publishing the Japanese Journal of Ophthalmology as its official English-language publication. Currently the journal is published bimonthly and accepts papers from authors worldwide. JJO has become an international interdisciplinary forum for the publication of basic science and clinical research papers.
