Abstract

Purpose

This study aimed to elucidate the distribution and morphological features of choroidal vortex veins in pachychoroid disease (PCD).

Design

Retrospective observational study.

Subjects

Patients with PCD included from January 2022 to June 2023.

Methods

We conducted a retrospective cross-sectional analysis using wide-field indocyanine green angiography (WF-ICGA) to assess choroidal vortex veins in PCD patients, categorizing them based on location (equatorial/posterior) and morphology (absent, incomplete, complete, complete with ampulla).

Main Outcome Measures

The incidence of different location and morphology of vortex veins in PCD.

Results

A total of 190 eyes from 99 PCD patients were examined. Notably, only 8.9 % (17/190) of eyes had posterior vortex veins. We identified 1620 vortex veins, predominantly equatorial (99 %, 1603/1620). Morphologically, the most common type was incomplete (61.9 %), followed by complete (19.5 %), absent (11.1 %), and complete with ampulla (7.5 %). The distribution of these veins varied, with the inferotemporal quadrant showing the highest prevalence at 26.9 %, followed by the superonasal (26.1 %), superotemporal (24.3 %), and inferonasal (22.7 %) quadrants. The median number of vortex veins per eye was 8, with a range from 5 to 15.

Conclusions

This study highlights that posterior vortex veins are less frequent in PCD eyes, with incomplete veins being the most prevalent. These findings provide important clinical evidence for understanding the distribution and morphologic characteristics of choroidal vortex veins in PCD, contributing to our knowledge of the pathophysiological mechanisms underlying this condition.

脉络膜病变中脉络膜涡状静脉的分布和形态特征

目的：本研究旨在阐明脉络膜漩涡静脉在脉络膜病变（PCD）中的分布和形态特征：设计：回顾性观察研究：方法：进行回顾性横断面研究：我们使用宽视野吲哚菁绿血管造影术（WF-ICHA）对PCD患者的脉络膜涡状静脉进行了回顾性横断面分析，并根据位置（赤道/后方）和形态（无、不完整、完整、完整伴有瓿）对其进行了分类：主要结果指标：PCD患者涡状静脉不同位置和形态的发生率：结果：共检查了 99 名 PCD 患者的 190 只眼睛。值得注意的是，只有 8.9%（17/190）的眼球有后涡状静脉。我们发现了 1620 条涡状静脉，主要是赤道静脉（99%，1603/1620）。从形态上看，最常见的类型是不完全静脉（61.9%），其次是完全静脉（19.5%）、无静脉（11.1%）和带安瓿的完全静脉（7.5%）。这些静脉的分布各不相同，其中颞下象限的发病率最高，为 26.9%，其次是鼻上象限（26.1%）、颞上象限（24.3%）和鼻下象限（22.7%）。每只眼睛涡状静脉数量的中位数为 8 条，范围从 5 到 15.结论：本研究强调，PCD眼球中后涡状静脉的出现率较低，其中不完整的静脉最为常见。这些发现为了解 PCD 中脉络膜涡状静脉的分布和形态特征提供了重要的临床证据，有助于我们了解该病症的病理生理机制。
