Optical coherence tomography (OCT) has been shown to be a valuable tool in glaucoma assessment. We investigated a new ultrahigh-resolution OCT (UHR-OCT) imaging system in glaucoma patients and compared the findings with those obtained by conventional-resolution OCT.
Retrospective comparative case series.
A normal subject and 4 glaucoma patients representing various stages of glaucomatous damage.
All participants were scanned with StratusOCT (axial resolution of approximately 10 mum) and UHR-OCT (axial resolution of approximately 3 microm) at the same visit.
Comparison of OCT findings detected with StratusOCT and UHR-OCT.
Ultrahigh-resolution OCT provides a detailed cross-sectional view of the scanned retinal area that allows differentiation between retinal layers. These UHR images were markedly better than those obtained by the conventional-resolution OCT.
Ultrahigh-resolution OCT provides high-resolution images of the ocular posterior segment, which improves the ability to detect retinal abnormalities due to glaucoma.
光学相干断层扫描(OCT)已被证明是青光眼评估中的一种有价值的工具。我们在青光眼患者中研究了一种新型超高分辨率OCT(UHR - OCT)成像系统,并将结果与传统分辨率OCT获得的结果进行比较。
回顾性比较病例系列。
一名正常受试者和4名代表青光眼损害不同阶段的青光眼患者。
所有参与者在同一次就诊时用StratusOCT(轴向分辨率约为10微米)和UHR - OCT(轴向分辨率约为3微米)进行扫描。
比较StratusOCT和UHR - OCT检测到的OCT结果。
超高分辨率OCT提供了扫描视网膜区域的详细横截面视图,能够区分视网膜各层。这些UHR图像明显优于传统分辨率OCT获得的图像。
超高分辨率OCT提供了眼后段的高分辨率图像,提高了检测青光眼所致视网膜异常的能力。
