目的。评估傅里叶域光学相干断层扫描 (FD-OCT) 作为对疑似前基质混浊的供体角膜进行传统裂隙灯检查的辅助手段。 方法。使用 FD-OCT 评估裂隙灯检查怀疑有前基质混浊的 7 个角膜。对每个角膜进行评估以确认混浊的存在，如果存在，则测量混浊的深度。 结果。不透明度深度范围为82μm至624μm。七个角膜中的五个的初始裂隙灯印模已通过 OCT 确认。在两个角膜中，OCT 结果与最初的裂隙灯印象不同。第一角膜的裂隙灯检查给出了前基质疤痕的印象，但 OCT 显示混浊仅限于上皮。第二角膜的裂隙灯检查提示混浊仅限于上皮，但 OCT 发现了明显的鲍曼氏疤痕。在所有情况下，眼库技术人员报告说，OCT 比裂隙灯更能清晰地确定角膜混浊的位置和深度。 结论。与裂隙灯检查相比，OCT 的高分辨率使其更容易确定角膜混浊的位置。这种增强的可视化可以改善有关供体角膜移植适宜性的决策。
Purpose. To evaluate Fourier-domain optical coherence tomography (FD-OCT) as an adjunct to traditional slit lamp examination of donor corneas with suspected Anterior Stromal Opacities. Methods. Seven corneas suspected of having anterior stromal opacities by slit lamp examination were evaluated with FD-OCT. Each cornea was evaluated to confirm the presence of opacity and, if present, the depth of opacity was measured. Results. The opacity depth ranged from 82 μm to 624 μm. The initial slit lamp impressions of five of the seven corneas were confirmed by OCT. In two corneas, the OCT findings were different from the initial slit lamp impressions. Slit lamp examination of the first cornea gave the impression of anterior stromal scarring, but OCT showed that the opacity was limited to the epithelium. Slit lamp examination of the second cornea suggested opacity limited to the epithelium, but OCT identified significant sub-Bowman's scarring. In all cases, the Eye Bank Technicians reported that the location and depth of corneal opacity were more sharply defined by OCT than by slit lamp. Conclusion. The high resolution of OCT makes it easier to determine the location of corneal opacities compared to slit lamp examinations. This enhanced visualization can improve decisions regarding transplant suitability of donor corneas.
