| Abstract Purpose: To determine the prevalence of uveal effusion in acute and chronic primary angle-closure (PACG). Methods: 78 eyes of 39 patients with acute PACG and 42 eyes of 21 patients with chronic PACG were included in the experiment, Ultrasound biomicroscopic examination was performed to diagnose uveal effusion and to measure anterior chamber depth(ACD). Results: Uveal effusion was demonstrated in 15 eyes (38.5%)（X2=9.47，P<0.05）. Among eyes with chronic PACG , uveal effusion was present in 5 (23.8%). In the chronic PACG group, the ACD with uveal effusion(1.91±0.24mm) was significantly shallower than that of the eyes without effusion(2.12±0.28mm)
Conclusions: Uveal effusion diagnosed by ultrasound biomicroscopic is a special feature and is prevalent in PACG；Uveal effusion with chronic PACG is associated with shallowing of ACD.
摘要 目的：探讨葡萄膜上腔积液在原发性闭角型青光眼中的发生状况。方法：60例120眼，其中急性闭角型青光眼病人39例78眼，慢性闭角型青光眼病人21例42眼，采用超声生物显微镜检查并进行前房深度测量。结果：急性闭角型青光眼病人中急性发作眼有15例（38.5%)，对侧眼4例（10%）出现葡萄膜上腔积液（X2=9.47，P<0.05）；慢性闭角型青光眼病人中5例（23.8%)出现葡萄膜上腔积液；慢闭病人中伴葡萄膜上腔积液眼前房深度为(1.91±0.24mm)，对侧眼为(2.12±0.28mm)，差异有显著性（P<0.05)。
结论：葡萄膜上腔积液是原发性闭角型青光眼发病中的一个特殊的特征性改变；葡萄膜上腔积液多伴有浅前房的发生。
