Abstract

Purpose

The aim of this study was to assess the impact of acute, heavy alcohol consumption on the ocular microvasculature, providing insight into the largely unexplored response of microvascular structures to excessive drinking.

Methods

Healthy volunteers in this prospective pilot study were tasked with consuming spirits, wine, and water at different times. Alcohol intake was measured according to body weight (g/kg). The ocular microvascular parameters primarily including choroidal volume (CV) and choroidal vessel volume (CVV) reflecting arteriolovenularity, and choroidal capillary density (CCD) reflecting capillary, were evaluated using swept-source optical coherence tomography angiography at baseline and 0.5-, 1-, 2-, and 3-hour post-consumption.

Results

A total of 34 eyes underwent 170 successful examinations in this study. After consuming spirits or wine, we observed significant decreases in CV and CVV values (all P < 0.01 for 0.5-, 1-, 2-, and 3-hour post-consumption), along with significant increase in CCD (P < 0.05 at 0.5-, 1-, 2-hour post-spirits consumption and 1-hour post-wine consumption). The most pronounced changes occurred 1-hour after spirits or wine consumption (all P < 0.001 in both univariate and multivariate model). However, post-consumption changes in the ocular microvasculature showed no significant differences between spirits and wine (P > 0.05). Additionally, no significant differences were observed in any parameters after water intake (all P > 0.05).

Conclusions

Excessive alcohol consumption leads to ocular arteriolovenular vasoconstriction and capillary vasodilation, most evident 1-hour post-consumption of spirits and wine. Our research provides insight into alcohol's immediate ocular microvascular effects, hinting at systemic microvascular effects.

酒精消费后脉络膜和视网膜微血管的定量评价:一项初步研究。
目的:本研究的目的是评估急性大量饮酒对眼部微血管的影响,为微血管结构对过量饮酒的反应提供深入了解。方法:在这项前瞻性先导研究中,健康志愿者被要求在不同时间饮用烈酒、葡萄酒和水。按体重(g/kg)测定酒精摄入量。眼底微血管参数主要包括脉络膜体积(CV)和脉络膜血管体积(CVV)反映动脉静脉,脉络膜血管密度(CCD)反映毛细血管,在基线和0.5小时,1小时,2小时和3小时后使用扫描源光学相干断层扫描血管造影评估。结果:本研究共成功检查34只眼170次。在饮用烈酒或葡萄酒后,我们观察到CV和CVV值显著降低(P均为  0.05)。此外,饮水后各项参数均无显著差异(P均为 > 0.05)。结论:过量饮酒可导致眼动静脉血管收缩和毛细血管舒张,且在饮酒后1小时最为明显。我们的研究揭示了酒精对眼部微血管的直接影响,暗示了对全身微血管的影响。
