Glaucoma: Overview

499
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

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:

  • 青光眼的诊断依赖于视野 (VF) 测试.
  • 准确地确定青光眼的阶段对于有效的治疗至关重要.
  • 目前的方法可能无法完全捕捉VF数据中的微妙变化.

研究的目的:

  • 评估深度学习 (DL) 模型,以区分正常视野和眼视野.
  • 通过使用模式偏差 (PD) 图表来评估DL模型在分期青光眼严重性方面的性能.
  • 将DL模型的结果与传统的机器学习 (ML) 分类器进行比较.

主要方法:

  • 训练DL模型 (ResNet18,VGG16) 在265个PD图表上从正常和眼的眼睛.
  • 将VF分为正常,早期,中度和晚期玻璃眼病阶段.
  • 采用五倍交叉验证和数据增强技术.
  • 使用全球指数 (MD,PSD,VFI) 对ML模型进行DL性能比较.

主要成果:

  • 在平衡,增强的PD图像上训练的ResNet18获得了96.8%的F1分数.
  • DL模型准确地定位了视野损失.
  • 机器学习 (随机森林) 获得了96%的F1分.
  • 该公司的业绩与传统的全球指数相当.

结论:

  • 在PD地块上训练的DL模型显示出对青光眼的检测和分期的希望.
  • DL模型可以将眼病的严重程度分为阶段,类似于米尔斯标准,仅使用PD图表.
  • 这种自动化方法可以帮助临床医生进行青光眼查和进展管理.
