Ultrasound biomicroscopy is a new imaging technology that uses high-frequency ultrasound and thus allows depiction of the anterior portion of the globe in microscopic resolution. It is independent on the clarity of the optical media and allows, for the first time, a non-invasive demonstration of the structures of the posterior chamber and their relationship to each other. Therefore, it is especially suitable for diagnosis and research on the various forms of glaucoma. Our examinations were performed with an ultrasound biomicroscope (UBM Humphrey Model 840) with a 50 MHz transducer. This allows resolution of structures up to 50 microns. Thirty-nine patients with different forms of glaucoma were examined: POAG, pigmentary glaucoma, pseudoexfoliation glaucoma, pupillary block, plateau iris syndrome, ciliolenticular block, congenital glaucoma, traumatic glaucoma and situations after glaucoma surgery. The following findings could be demonstrated: configuration of the anterior chamber angle region, iris curvature, ciliary body and lens position, differentiation between solid and cystic tumors, traumatic changes and trabeculectomy openings. With this information ultrasound biomicroscopy offers additional details for the differential diagnosis and treatment of various forms of glaucoma.
超声生物显微镜检查是一种新的成像技术，它使用高频超声，从而能够以微观分辨率描绘眼球的前部。它不依赖于眼内光学介质的清晰度，首次实现了对后房结构及其相互关系的无创显示。因此，它特别适用于各种类型青光眼的诊断和研究。我们使用配备50MHz换能器的超声生物显微镜（UBM Humphrey Model 840）进行检查。这能够分辨出高达50微米的结构。对39例不同类型青光眼患者进行了检查，包括原发性开角型青光眼、色素性青光眼、假性剥脱性青光眼、瞳孔阻滞、房角高原综合征、睫状晶状体阻滞、先天性青光眼、外伤性青光眼以及青光眼手术后的情况。可以观察到以下结果：前房角区域的形态、虹膜曲率、睫状体和晶状体位置、实性与囊性肿瘤的鉴别、外伤改变以及小梁切除术切口。基于这些信息，超声生物显微镜检查为各种类型青光眼的鉴别诊断和治疗提供了更多细节。
