项目摘要

Project Summary/Abstract Human vision starts when photoreceptors collect and respond to light. Normal photoreceptor function is essential for normal vision, yet techniques to assess these processes in vivo are limited. New optical modalities that are rapid, specific, and non‐invasive promise to greatly expand our capability to monitor more accurately and completely photoreceptors. This study takes advantage of unique adaptive‐optics OCT instrumentation developed in my laboratory in conjunction with custom algorithms for sub‐cellular image registration and phase‐sensitive detection to measure anatomical and physiological properties of individual photoreceptors. We will use this technique to investigate three specific aims that quantify the spectral sensitivity profiles of photoreceptors, the expression of photoreceptor spectral types in color vision deficiencies, and the temporal dynamics of photoreceptor loss in retinitis pigmentosa patients. The long term goal of this research is to establish high resolution, high specificity optical techniques as valid tools for probing structure and physiologic processes of the retina at the cellular scale. The resulting ability to study cells in vivo will improve early detection of and treatment monitoring for diseases that impact the retina.

项目摘要/摘要当光感受器收集并响应光线时，人类的视力开始。正常的感光器功能为对于正常视力的必不可少，但是在体内评估这些过程的技术是有限的。新的光学方式快速，具体且无创的承诺可以很好地扩展我们的能力，以更准确地监视和完全感受器。这项研究利用了我在我的实验室中开发的独特的自适应启示仪与用于亚细胞图像注册和相位敏感检测的自定义算法的连接测量单个光感受器的解剖学和物理特性。我们将使用这种技术来研究量化感光体的光谱灵敏度曲线的三个特定目标，即光视觉缺陷中的光感受器光谱类型，以及感光受体损失的临时动力学这项研究的长期目标是建立高分辨率，高特异性光学技术是视网膜在细胞处的视网膜探测结构和生理过程的有效工具规模。在体内研究细胞的结果能力将改善对治疗的早期检测和治疗监测影响视网膜的疾病。
