Abstract

ABSTRACT We conducted this study to assess the effect of religious fasting on intraocular pressure (IOP) as well as retinal parameters and retinal thickness during Ramadan using optical coherence tomography angiography (OCTA) performed on a spectral domain device. All the participants ate a pre-dawn meal and drink, and then fasted for at least 15 hours. We assessed a total of 61 eyes from 31 healthy volunteers with a mean age of 32.87 ± 8.07. A significant decrease was found in the median IOP after fasting at 10.00 mmHg in comparison with the pre-fasting value of 12.00 mmHg (p < .0001). Retinal peri-papillary capillary (RPC) whole image, RPC inside disk, and RPC mean values showed significant decreases after fasting (p = .011, .012, and .032 respectively). RPC whole vessel density (VD), RPC inside VD, and RPC VD mean values also showed significant decreases after fasting period (p = .025, <.0001, and .003, respectively). Religious fasting during the warm season could decrease IOP. It could also reduce the blood flow of the retina, specifically the macula, and the retinal peri-papillary VD.

利用光学相干断层扫描血管造影评价宗教禁食对视网膜血管密度和视网膜厚度的影响

本研究采用光学相干断层扫描血管造影(OCTA)在光谱域设备上进行，以评估斋月期间宗教禁食对眼压(IOP)、视网膜参数和视网膜厚度的影响。所有的参与者都在黎明前吃了一顿饭和饮料，然后禁食至少15个小时。我们对31名平均年龄32.87±8.07岁的健康志愿者共61只眼睛进行了评估。与禁食前的12.00 mmHg相比，空腹后中位眼压显著下降(p < 0.0001)。禁食后视网膜乳头周围毛细血管(RPC)全像、盘内RPC、RPC均值均显著降低(p分别为0.011、0.012、0.032)。空腹后，RPC全血管密度(VD)、VD内RPC、RPC VD平均值均显著降低(p = 0.025， < 0.05)。分别为0001和0.003)。温暖季节的宗教斋戒可能会降低眼内压。它还可以减少视网膜的血流量，特别是黄斑和视网膜乳头状周围VD。
