摘要:

视网膜组织的检测有可能提供一种独特的方法和技术来量化AD不同疾病阶段的变化。此项meta分析旨在分析光学相干断层扫描参数与阿尔茨海默病(AD)的关联,以及视网膜测量是否可用于分辨AD。因此,在Google Scholar、Web of Science和PubMed数据库中系统检索了评估AD和对照组中视网膜神经纤维层厚度和视网膜微血管的研究。最终73项研究(5850名患者,2249名AD患者和3601名对照者)被纳入meta分析中。与对照组比较,AD患者的视网膜神经纤维层厚度较小(SMD: 0.79, 95%CI:-1.03- -0.54,P<0.00001)。AD光学相干断层扫描测量的黄斑参数黄斑厚度(pooled SMD: -0.44, 95%CI:-0.67到-0.20,P=0.0003),眼窝厚度(pooled SMD: -0. 39, 95% CI: -0.58 to -0.19, P<0.0001), 神经节细胞的胞体内网状层(GCIPL) (SMD: -1.26 (95% CI: -2.24 to -0.27, P=0.01) 和黄斑体积  (pooled SMD: - 0.41,95% CI -0.76 - - 0.07, P<0.02)均明显小于对照组。光学相干断层扫描血管成像参数进行分析发现,AD患者浅层血管密度(SVD)(pooled SMD: -0.42,95%CI:-0.68至-0.17,P=0.0001)和深层血管密度(DVD)(pooled SMD: -0.46,95%CI:-0.75- -0.18,P=0.001)均明显低于对照组。此meta分析中提供的光学相干断层扫描数据有助于分析AD患者的视网膜和微血管变化,从而为AD的监测和早期诊断提供数据支持。

Abstract: Examining the retinal tissue has the potential to provide a unique method and technique to quantify Alzheimer’s disease-related changes in participants at various stages of the disease. In this meta-analysis, we aimed to investigate the association of various optical coherence tomography parameters with Alzheimer’s disease and whether retinal measurements can be used to differentiate between Alzheimer’s disease and control subjects. Scientific databases including Google Scholar, Web of Science, and PubMed were systematically searched for published articles that evaluated retinal nerve fiber layer thickness and retinal microvascular network in Alzheimer’s disease and control subjects. Seventy-three studies (5850 participants, including 2249 Alzheimer’s disease patients and 3601 controls) were included in this meta-analysis. Relative to controls, Alzheimer’s disease patients had a significantly lower global retinal nerve fiber layer thickness (standardized mean difference [SMD] = –0.79, 95% confidence intervals [CI]: –1.03 to –0.54, P < 0.00001) as well as each quadrant being thinner in Alzheimer’s disease versus controls. Regarding macular parameters, values measured by optical coherence tomography were significantly lower in Alzheimer’s disease than controls for macular thickness (pooled SMD: –0.44, 95% CI: –0.67 to –0.20, P = 0.0003), foveal thickness (pooled SMD = –0.39, 95% CI: –0.58 to –0.19, P < 0.0001), ganglion cell inner plexiform layer  (SMD = –1.26, 95% CI: –2.24 to –0.27, P = 0.01) and macular volume (pooled SMD = –0.41, 95% CI –0.76 to –0.07, P = 0.02). Analysis using optical coherence tomography angiography parameters revealed mixed results between Alzheimer’s disease and controls. Superficial vessel density (pooled SMD = –0.42, 95% CI: –0.68 to –0.17, P = 0.0001) and deep vessel density (pooled SMD = –0.46, 95% CI: –0.75 to –0.18, P = 0.001) were found to be thinner in Alzheimer’s disease patients whereas the foveal avascular zone (SMD = 0.84, 95% CI: 0.17–1.51, P = 0.01) was larger in controls. Vascular density and thickness of various retinal layers were decreased in Alzheimer’s disease patients compared to controls. Our results provide evidence for optical coherence tomography technology having the potential to detect retinal and microvascular changes in patients diagnosed with Alzheimer’s disease and aid in monitoring and early diagnosis methods.
