项目摘要

Project Summary Glaucoma is a leading cause of vision morbidity and blindness worldwide. Early disease detection and sensitive monitoring of progression are crucial to allow timely treatment for preservation of vision. The introduction of ocular imaging technologies significantly improves these capabilities, but in clinical practice there are still substantial challenges at certain stages of the disease severity spectrum, specifically in the early stage and in advanced disease. These difficulties are due to a variety of causes that change over the course of the disease, including large between-subject variability, inherent measurement variability, image quality, varying dynamic ranges of measurements, minimal measurable level of tissues, etc. In this proposal, we build on our long-standing contribution to ocular imaging and propose novel and sensitive means to detect glaucoma and its progression that are optimized to the various stages of disease severity. We will use information gathered from visual fields (functional information) and a leading ocular imaging technology – optical coherence tomography (OCT; structural information) to map the capability of detecting changes across the entire disease severity spectrum to identify optimal parameters for each stage of the disease. Both commonly used parameters provided by the technologies and newly developed parameters with good diagnostic potential will be analyzed. We will use state-of-the-art automated computerized machine learning methods, namely the deep learning approach, to identify structural features embedded within OCT images that are associated with glaucoma and its progression without any a priori assumptions. This will provide novel insight into structural information, and has shown very encouraging preliminary results. We will also utilize a new imaging technology, the visible light OCT, to generate retinal images with outstanding resolution to extract information about the oxygen saturation of the tissue. This will provide in-vivo, real time, and noninvasive insight into tissue functionality. Taken together, this program will advance the use of structural and functional information with a substantial impact on the clinical management of subjects with glaucoma

项目概要青光眼是全世界视力发病和失明的主要原因。早期疾病检测和治疗。敏感的进展监测对于及时治疗以保留视力至关重要。眼部成像技术的引入显着提高了这些能力，但在临床实践中在疾病严重程度的某些阶段，特别是在早期阶段，仍然面临着巨大的挑战这些困难是由于在疾病过程中发生变化的各种原因造成的。疾病，包括受试者之间较大的变异性、固有的测量变异性、图像质量、不同的动态测量范围、组织的最小可测量水平等。在这个提案中，我们建立表彰我们对眼部成像的长期贡献，并提出新颖且灵敏的青光眼检测方法我们将使用针对疾病严重程度的各个阶段进行优化的信息及其进展。从视野（功能信息）和领先的眼部成像技术 - 光学收集相干断层扫描（OCT；结构信息）可绘制检测整个组织变化的能力整个疾病严重程度范围，以确定疾病每个阶段的最佳参数。使用技术提供的参数和新开发的具有良好诊断潜力的参数我们将使用最先进的自动化计算机机器学习方法，即深度学习方法，识别嵌入 OCT 图像中的结构特征，这些特征与青光眼及其进展无需任何先验假设，这将为结构提供新的见解。信息，并显示出非常令人鼓舞的初步结果，我们还将利用一种新的成像技术。可见光 OCT 技术，生成具有出色分辨率的视网膜图像以提取信息关于组织的氧饱和度，这将提供对组织的体内、实时、无创洞察。总而言之，该程序将促进结构和功能信息的使用。对青光眼受试者的临床管理产生重大影响
