    背景情况:

    • 传统的光学连贯性断层扫描 (OCT) 系统用于视网膜成像,往往需要脑膜 (瞳孔扩张) 剂.
    • 瞳孔膨胀增加了视网膜检查的时间,成本,不适和潜在的医疗风险.
    • 现有的超广场OCT系统在视野和工作距离方面面临限制.

    研究的目的:

    • 为了展示一个新的非肌性超广场OCT视网膜成像系统.
    • 为了改善成像视野,侧面分辨率和患者舒适度.
    • 为了应对与传统的水系海洋海洋系统相关的挑战.

    主要方法:

    • 开发一种使用定制光学的新型非米德里亚特超广场OCT系统.
    • 系统设计用于超宽的100度视野和宽厚的16毫米工作距离.
    • 评估成像性能,包括横向分辨率和避免没有药理扩张的工件.

    主要成果:

    • 该系统实现了超宽的100度视野,中心侧面分辨率为20微米.
    • 工作距离保持在比现有系统长2-3倍的距离.
    • 避免了虹膜细分器件的出现,从而实现了无透症的衍射有限的超广场成像.
