Ultrasound biomicroscopy (UBM) is a high-resolution ultrasound technique that allows noninvasive in vivo imaging of structural details of the anterior ocular segment at near light microscopic resolution and provides detailed assessment of anterior segment structures, including those obscured by normal anatomic and pathologic relations. We summarize UBM applications in glaucoma. In some cases UBM elucidates the mechanism of elevated intraocular pressure by showing the relationship between the peripheral iris and the trabecular meshwork. It can be used to study the causes of secondary glaucoma, for example, the pigment dispersion syndrome, lens-induced glaucomas, ciliary block, cysts, and solid tumors of the anterior segment. It can also assess the effects of various interventions such as laser iridotomy, trabeculectomy, and non-penetrating drainage surgery. Precise quantitative evaluation of the anterior chamber angle structures can help in diagnosis and management of various pathologies related to glaucoma.
超声生物显微镜（UBM）是一种高分辨率超声技术，可在近光学显微镜分辨率下对眼前节的结构细节进行非侵入性的活体成像，并提供对眼前节结构的详细评估，包括那些被正常解剖和病理关系遮挡的结构。我们总结了 UBM 在青光眼中的应用。在某些情况下，UBM 通过显示周边虹膜与小梁网之间的关系，阐明了眼压升高的机制。它可用于研究继发性青光眼的病因，例如色素播散综合征、晶状体相关性青光眼、睫状体阻滞、囊肿和前节实性肿瘤。它还可以评估各种干预措施的效果，如激光虹膜切开术、小梁切除术和非穿透性引流手术。对前房角结构的精确定量评估有助于诊断和处理与青光眼相关的各种病变。
