Vision

52.9K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

科学领域:

  • 眼科医生 眼科 眼科
  • 人工智能的人工智能
  • 医疗成像医学成像

背景情况:

  • 精确的眼镜校正视敏度 (VA) 对于管理糖尿病黄斑 (DME) 等眼科疾病至关重要.
  • 目前的方法需要训练有素的技术人员,增加成本和访问时间.
  • 人工智能为远程或自动VA评估提供了一个潜在的解决方案.

研究的目的:

  • 评估验证的人工智能 (AI) 算法的准确性,以估计患有糖尿病黄斑 (DME) 患者的眼镜校正视敏度 (VA) 的 fundus 照片.
  • 评估在临床实践环境中使用AI用于VA估计的可行性.

主要方法:

  • 对141名患有DME的患者的非识别性 fundus 照片进行了回顾性横截面研究.
  • 眼球图像与技术人员测量的眼镜校正VA从眼睛图表相匹配.
  • 以前经过验证的AI算法被用于从 fundus 图像中估计VA.

主要成果:

  • 人工智能算法显示,VA的平均绝对误差 (MAE) 在10/20和20/20之间为1.16至1.92行,VA在25/20和20/80之间为1.42至1.44行.
  • 对于VA 20/80或更好的患者,准确度大约在1至1.5行之内.
  • 分析仅限于VA 20/100或更差的图像.

结论:

  • 人工智能对 fundus 照片的评估可以准确地估计DME患者的眼镜校正VA,视力敏度为20/80或更好.
  • 这项技术有望在传统临床环境之外促进VA监测,从而降低成本并提高可访问性.
  • 对于视力敏度非常低的患者,需要进一步的研究.
