摘要

目的：后囊破裂（PCR）是白内障手术中出现的一种严重并发症。后极性白内障（PPC）患者是 PCR 的高危人群。尽管散瞳剂有明显的副作用，但它能在裂隙灯检查中提高白内障后方的能见度，有助于识别 PPC。超宽视场（UWF）视网膜成像系统无需借助眼药水，就能在眼底图像中看到白内障在视网膜上的投影（阴影）。PPC 与投影阴影之间的关系仍有待探索。我们假设了一种白内障-阴影-投影理论，然后通过开发一种深度学习算法对其进行了验证，该算法可使用眼底图像自动、稳定地筛查白内障：数据来自远东纪念医院眼科，并获得了医院机构审查委员会的许可：设计：回顾性病历审查数据，包括 UWF 眼底图像：我们根据白内障-阴影-投影理论开发了一种深度学习算法，用于自动检测白内障。我们收集了带有 UWF 眼底图像的回顾性数据（n=546），并对各种模型架构和视场（FOV）进行了优化测试：结果：在临床验证数据集（n=103）上，最终模型的总体准确率达到 80%，在 PPC 筛查中的灵敏度为 88.2%，特异度为 93.4%：这项研究确定了PPC与投影阴影之间的重要关系，使外科医生能够在术前识别潜在的PPC风险，降低白内障手术中后囊破裂的发生率。

Innovative utilization of ultra-wide field fundus images and deep learning algorithms for screening high-risk posterior polar cataract.

Purpose: To test a cataract shadow projection theory and validate it by developing a deep learning algorithm that enables automatic and stable posterior polar cataract (PPC) screening using fundus images.

Setting: Department of Ophthalmology, Far Eastern Memorial Hospital, New Taipei, Taiwan.

Design: Retrospective chart review.

Methods: A deep learning algorithm to automatically detect PPC was developed based on the cataract shadow projection theory. Retrospective data (n = 546) with ultra-wide field fundus images were collected, and various model architectures and fields of view were tested for optimization.

Results: The final model achieved 80% overall accuracy, with 88.2% sensitivity and 93.4% specificity in PPC screening on a clinical validation dataset (n = 103).

Conclusions: This study established a significant relationship between PPC and the projected shadow, which may help surgeons to identify potential PPC risks preoperatively and reduce the incidence of posterior capsular rupture during cataract surgery.
