Abstract

Purpose: To investigate the relationship between the fundus sex index obtained from fundus photographs and body height or axial length in the Kumejima population.

Study design: Prospective cross-sectional observational population study.

Methods: Using color fundus photographs obtained from the Kumejima population, 1,653 healthy right eyes with reliable fundus parameter measurements were included in this study. The tessellation fundus index was calculated as R/(R + G + B) using the mean value of the red-green-blue intensity in the eight locations around the optic disc and foveal region. The optic disc ovality ratio, papillomacular angle, and retinal vessel angle were quantified as previously described. The masculine or feminine fundus was quantified using machine learning (L2 regularized binominal logistic regression and leave one out cross validation), with the range of 0-1 as the predictive value, and defined as the fundus sex index. The relationship between the fundus sex index and body height or axial length was investigated using Spearman's correlation.

Results: The mean age of the 838 men and 815 women included in this study was 52.8 and 54.0 years, respectively. The correlation coefficient between fundus sex index and body height was - 0.40 (p < 0.001) in all, 0.01 (p = 0.89) in men, and - 0.04 (p = 0.30) in women, and that between fundus sex index and axial length was - 0.23 (p < 0.001) in all, - 0.12 (p < 0.001) in men, and - 0.13 (p < 0.001) in women.

Conclusion: This study shows that a larger number of masculine fundi tend to have longer axial lengths in each sex group. However, sex index was not significantly related with body height either in men or in women.

久米岛人群中使用彩色眼底参数获得的眼底性别指数与身高或轴长之间的关系。
目的:在久米岛人群中调查通过眼底照片获得的眼底性别指数与身高或轴长之间的关系:研究设计:前瞻性横断面观察人群研究:使用从久米岛人群中获得的彩色眼底照片,将 1,653 只具有可靠眼底参数测量值的健康右眼纳入本研究。通过计算视盘和眼窝周围八个位置的红绿蓝强度平均值,以 R/(R + G + B) 表示魔方眼底指数。视盘椭圆率、视乳头角和视网膜血管角的量化方法如前所述。通过机器学习(L2 正则化二项式逻辑回归和留一交叉验证),以 0-1 为预测值范围,量化眼底的男性化或女性化,并将其定义为眼底性别指数。眼底性别指数与身高或轴长之间的关系采用斯皮尔曼相关性进行研究:838 名男性和 815 名女性的平均年龄分别为 52.8 岁和 54.0 岁。眼底性别指数与身高之间的相关系数为-0.40(p 结论:眼底性别指数与身高之间的相关系数为-0.40(p):本研究表明,在每个性别组中,男性眼底数量越多,轴向长度越长。然而,性别指数与男性或女性的身高均无明显关系。

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.
