Abstract

Purpose: Asymmetric dilated vortex veins (ADVV) extending continuously to the vortex ampullae seen on Indocyanine green angiography (ICGA) findings, are thought to indicate choroidal venous congestion in central serous chorioretinopathy (CSC). In addition, the sclera is thickened compared to normal eyes, suggesting that obstruction of the scleral passage is the pathophysiological mechanism of CSC. The purpose of this study was to examine the choroidal circulation in and around the vortex vein ampulla.

Study design: Single-center retrospective study.

Methods: The subjects were 23 CSC eyes with macular central serous detachment (SRD) undergoing wide-field ICGA with Spectralis^®. Choroidal circulation time was defined as the time from the onset of filling in the choroidal artery to the first appearance of dye in the vortex vein ampulla. The choroidal circulation time in the superior and inferior vortex veins were measured separately. The relationship between the ADVV and the choroidal circulation time was investigated.

Results: The mean choroidal circulation time was 4.44 seconds for the superior temporal side and 4.33 seconds for the inferior temporal side, with no significant difference (p=0.494). The mean choroidal circulation time was 3.89 seconds on the ADVV side and 4.88 seconds on the non-ADVV side, with a shorter mean circulation time on the ADVV side (p=0.00005). In 21 of 23 eyes, there was a time difference in the filling of the choroidal veins entering the vortex vein ampulla.

Conclusion: On the side of the ADVV, no obstruction to the passage of the sclera is thought to have occurred.

中枢性浆液性脉络膜视网膜病变的宽视场吲哚菁绿血管造影显示脉络膜循环时间。

目的：吲哚菁绿血管造影（ICGA）显示不对称扩张漩涡静脉（ADVV）持续延伸至漩涡壶腹，被认为是中枢性浆液性脉络膜视网膜病变（CSC）脉络膜静脉充血的提示。此外，巩膜较正常眼增厚，提示巩膜通道阻塞是CSC的病理生理机制。本研究的目的是检查涡旋静脉壶腹内及其周围的脉络膜循环。研究设计：单中心回顾性研究。方法：以23只黄斑中央浆液脱离（SRD）的CSC眼为研究对象，应用Spectralis®进行大视场ICGA。脉络膜循环时间定义为从脉络膜动脉开始充盈到旋涡静脉壶腹第一次出现染料的时间。分别测定上、下涡旋静脉脉络膜循环时间。研究了ADVV与脉络膜循环时间的关系。结果：颞上侧脉络膜循环时间平均为4.44 s，颞下侧平均为4.33 s，差异无统计学意义（p=0.494）。ADVV侧平均脉络膜循环时间为3.89 s，非ADVV侧平均脉络膜循环时间为4.88 s， ADVV侧平均脉络膜循环时间更短（p=0.00005）。23眼中有21眼进入涡旋静脉壶腹的脉络膜静脉充盈存在时间差。结论：在ADVV一侧，未发生巩膜通道阻塞。

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.
