Abstract

Rod-dominated transient retinal phototropism (TRP) has been observed in freshly isolated retinas, promising a noninvasive biomarker for objective assessment of retinal physiology. However, in vivo mapping of TRP is challenging due to its subcellular signal magnitude and fast time course. We report here a virtually structured detection-based super-resolution ophthalmoscope to achieve subcellular spatial resolution and millisecond temporal resolution for in vivo imaging of TRP. Spatiotemporal properties of in vivo TRP were characterized corresponding to variable light intensity stimuli, confirming that TRP is tightly correlated with early stages of phototransduction.

摘要

杆状细胞主导的瞬时视网膜光偏向性(TRP)已在新鲜离体视网膜中观察到,这为客观评估视网膜生理提供了一种非侵入性的生物标志物。然而,由于其亚细胞信号幅度和快速时间过程,体内 TRP 的映射具有挑战性。我们在这里报告了一种基于虚拟结构检测的超分辨率眼底镜,以实现亚细胞空间分辨率和毫秒时间分辨率,用于体内 TRP 的成像。与可变光强刺激相对应的体内 TRP 的时空特性进行了特征描述,证实 TRP 与光转导的早期阶段密切相关。
