Malignant glaucoma (ciliary block glaucoma; aqueous misdirection glaucoma) is an incompletely understood, rare and serious complication of intraocular surgery.
A woman with pseudophakic malignant glaucoma underwent successful neodymium: YAG (Nd:YAG) laser photodisruption of the anterior hyaloid face with resolution of the glaucoma. High-resolution ultrasound biomicroscopy was used to image the anterior segment and anterior chamber angle before and after laser surgery.
Ultrasound biomicroscopy provided cross-sectional images of the iris, posterior chamber intraocular lens (IOL), and ciliary body and their relative positions before and after resolution of the malignant glaucoma. Anterior rotation of the ciliary body and anterior chamber shallowing normalized after rupture of the anterior hyaloid face.
High-resolution ultrasound biomicroscopy provided images consistent with accepted concepts of the pathophysiology of this disease and offers great promise for the future elucidation of the anatomic mechanisms underlying various forms of glaucoma.
恶性青光眼（睫状环阻滞性青光眼；房水错向性青光眼）是一种尚未完全被理解的、罕见且严重的眼内手术并发症。
一名人工晶状体性恶性青光眼女性患者接受了钕：钇铝石榴石（Nd:YAG）激光对前玻璃体膜的光破裂治疗，青光眼得以缓解。使用高分辨率超声生物显微镜对激光手术前后的眼前节和前房角进行成像。
超声生物显微镜提供了恶性青光眼缓解前后虹膜、后房型人工晶状体（IOL）和睫状体及其相对位置的横截面图像。前玻璃体膜破裂后，睫状体向前旋转和前房变浅恢复正常。
高分辨率超声生物显微镜提供的图像与该疾病病理生理学的公认概念一致，并为未来阐明各种形式青光眼的解剖学机制带来了巨大希望。
