Analysis of choroidal thickness in patients with ocular ischemic syndromeFU Qiang, WANG Hongxing Department of Ophthalmology, Beijing Chuiyangliu Hospital, Beijing 100022, ChinaAbstract: Objective〓

Spectral-domain optical coherence tomography(SD-OCT)was used to measure and observe the characteristics of the subfoveal choroidal thickness(SFCT)in patients with ocular ischemic syndrome(OIS)as well as explore the indicators for early evaluation of OIS. MethodsThis was a retrospective case-control study. Forty-eight patients(48 eyes)were included between January 2017 and January 2020. The patients were divided into two groups: the OIS and the control groups, with each consisting of 24 patients(24 eyes). Their basic information, including age, gender, body mass index(BMI), and the history of diabetes, hypertension, and hyperlipidemia, was collected. SFCT was measured using SD-OCT in EDI mode. The basic data and SFCTs of the two groups were compared. ResultsThere were no significant differences between the ages, gender, BMIs, and the prevalence of diabetes, hypertension, and hyperlipidemia of the two groups(all P>0.05). The mean SFCT of the OIS group was 204.83±27.34 μm, and that of the control group was 226.58±33.49 μm. The differences between the two groups were statistically significant(t=2.464, P=0.018). ConclusionsSFCT was thinner in patients with OIS. SFCT can be used as an indicator for early assessment of OIS.

    Spectral-domain optical coherence tomography(SD-OCT)眼缺血综合征［1］(ocular ischemic syndrome, OIS)由慢性严重的颈动脉阻塞或狭窄所致脑和眼的供血不足而产生一系列颅内缺血和眼部缺血的临床综合征。OIS可造成脑卒中［2］、心肌梗死［3］等致命性疾病的发生, 也可引起永久性视力损伤［4］。有研究表明［5］眼部缺血会先于脑血管病的发生。因此探索OIS患者眼部的评估指标对于预警致命性的心脑血管事件的发生有至关重要的意义。我们应用频域光学相干断层扫描仪(spectral-domain optical coherence tomography, SD-OCT)的增强深度成像(enhanced depth imaging, EDI)模式, 测量黄斑中心凹下脉络膜厚度(subfoveal choroidal thickness, SFCT), 旨在观察OIS患者SFCT的特征, 进一步探索早期评估OIS的指标。
