Ultrasound biomicroscopic examination of secondary pupillary block glaucoma
Wang T; Liu L; Zhihat HChinese Journal of Ophthalmology 2000; 36: 413
OBJECTIVE: To study the ultrasound biomicroscopy of secondary pupillary block glaucoma. METHODS: Eleven cases with pupillary block glaucoma diagnosed by ultrasound biomicroscopy were studied, which had been suspected malignant glaucoma from the beginning. RESULTS: There had been no obviously typical characteristics of pupillary block glaucoma in the ultrasound biomicroscopy images in these cases. However, the existence of posterior chambers in each cases strongly supported the diagnosis of papillary block glaucoma. The imaging characteristics of ultrasound biomicroscopy were different in terms of the different primary disorders that resulted in the papillary block glaucoma, including iridocyclitis, lens subluxation resulting from trauma, and glaucoma filtration surgery. In the cases of lens subluxation, the main characteristic was the increase of the distance between the lens and the ciliary process at the site of subluxation and the lens forward movement. In the cases of indocyclitis, anterior and posterior synechiae were the main characteristics. In the cases of glaucoma filtration surgery, there were two main characteristics. One was that the distance between the ciliary process and the equator of the lens was obvious, and the other was the occlusion of the inner ostium of glaucoma filtration surgery or peripheral iridectomy. CONCLUSIONS: Ultrasound biomicroscopy is important in the diagnosis of secondary pupillary block glaucoma and the differentiation between this and malignant glaucoma. Whether the posterior chamber exists or not is the difference between papillary block glaucoma and malignant glaucoma.LA: Chinese
