PURPOSE
To evaluate the ability of optical coherence tomography (OCT), designed primarily to image the posterior segment, to visualize the anterior chamber angle (ACA) in patients with different angle configurations.
METHODS
In a prospective observational study, the anterior segments of 26 eyes of 26 patients were imaged using the Zeiss Stratus OCT, model 3000. Imaging of the anterior segment was achieved by adjusting the focusing control on the Stratus OCT. A total of 16 patients had abnormal angle configurations including narrow or closed angles and plateau irides, and 10 had normal angle configurations as determined by prior full ophthalmic examination, including slit-lamp biomicroscopy and gonioscopy.
RESULTS
In all cases, OCT provided high-resolution information regarding iris configuration. The ACA itself was clearly visualized in patients with narrow or closed angles, but not in patients with open angles.
CONCLUSIONS
Stratus OCT offers a non-contact, convenient and rapid method of assessing the configuration of the anterior chamber. Despite its limitations, it may be of help during the routine clinical assessment and treatment of patients with glaucoma, particularly when gonioscopy is not possible or difficult to interpret.
目的
评估主要用于眼后节成像的光学相干断层扫描（OCT）对不同房角结构患者眼前房角（ACA）的可视化能力。
方法
在一项前瞻性观察研究中，使用蔡司Stratus OCT 3000型对26例患者的26只眼的前段进行成像。通过调整Stratus OCT上的聚焦控制实现前段成像。共有16例患者房角结构异常，包括窄角或闭角以及房角劈裂，10例患者根据先前的全面眼科检查（包括裂隙灯生物显微镜检查和前房角镜检查）确定房角结构正常。
结果
在所有病例中，OCT提供了有关虹膜结构的高分辨率信息。窄角或闭角患者的ACA本身清晰可见，但开角患者则不然。
结论
Stratus OCT提供了一种非接触、方便且快速的评估前房结构的方法。尽管有其局限性，但在青光眼患者的常规临床评估和治疗中可能会有所帮助，特别是在前房角镜检查无法进行或难以解释时。
