Abstract

Purpose: This study aimed to investigate the choroidal thickness (ChT) distribution in adult myopic eyes, focusing on the macular, nasal midperiphery, and temporal midperiphery regions, and to explore its relationship with axial length (AL) and refractive error.

Study design: A cross-sectional, observational study.

Methods: Twenty-nine eyes of 29 adult volunteers were examined. ChT was measured using high-speed swept-source optical coherence tomography covering an area of 50 degrees in three different regions: centered at macular, nasal side at 33 degrees, and temporal side at 33 degrees. Statistical analyses were performed to assess differences in ChT between regions and correlations with AL and spherical equivalent (SE).

Results: ChT was found to be thickest in the macular region, followed by the nasal and temporal midperiphery regions. Significant correlations were observed between AL/SE and ChT in the macular and temporal regions, but not in the nasal region. The temporal midperiphery showed the strongest correlation with AL and SE.

Conclusion: This study revealed a nasal-temporal asymmetry in ChT distribution in myopic eyes, with the temporal midperiphery showing the thinnest ChT. The strong correlations between ChT in the temporal midperiphery and AL/SE suggest a role for the temporal choroid in axial elongation and myopia progression. These findings highlight the importance of considering peripheral ChT in understanding ocular growth and myopia management.

黄斑、鼻中周和颞中周区域的脉络膜厚度及其与轴长和屈光不正的关系。

目的：本研究旨在调查成人近视眼脉络膜厚度（ChT）的分布，重点是黄斑、鼻中周和颞中周区域，并探讨其与轴长（AL）和屈光不正的关系：研究设计：横断面观察研究：方法：对 29 名成年志愿者的 29 只眼睛进行检查。使用高速扫源光学相干断层扫描测量了三个不同区域 50 度的 ChT：黄斑中心、鼻侧 33 度和颞侧 33 度。进行统计分析以评估不同区域之间 ChT 的差异以及与 AL 和球面等值（SE）的相关性：结果：发现黄斑区的 ChT 最厚，其次是鼻侧和颞侧中周区。在黄斑区和颞区，AL/SE 与 ChT 之间存在显著相关性，但在鼻区则没有。颞中周与 AL 和 SE 的相关性最强：这项研究揭示了近视眼ChT分布的鼻颞不对称现象，颞中周的ChT最薄。颞中周的ChT与AL/SE之间的强相关性表明，颞脉络膜在轴伸长和近视发展中起着重要作用。这些发现强调了在了解眼球生长和近视管理时考虑周边脉络膜厚度的重要性。

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.
