急性闭角型青光眼完全缓解患者双眼眼前节和睫状体解剖相关参数的比较研究

Anterior segment parameters comparison between attack eyes and fellow eyes after complete remission of primary acute angle-closure glaucoma

目的比较急性闭角型青光眼完全缓解患者发作眼和对侧眼眼前节和睫状体参数,探讨发作眼的眼前节解剖危险因素。方法选取2015年1月至2015年12月于首都医科大学附属北京同仁医院就诊的15例急性闭角型青光眼完全缓解无三联征的患者为研究对象,使用超声生物显微镜(ultrasound biomicroscopy,UBM)采集发作眼和对侧眼的眼前节图像,使用Adobe Photoshop软件测量前房深度、晶状体前凸度、巩膜突距离、睫状沟距离及睫状体面积,并进行分析。结果发作眼的前房深度显著浅于对侧眼(P<0.05),晶状体前凸度显著高于对侧眼(P<0.05),睫状体面积(12点和6点)均显著大于对侧眼(P<0.05),但其巩膜突距离和睫状沟距离与对侧眼比较均无显著差异(P>0.05)。结论晶状体相对位置靠前、睫状体面积大可能是急性闭角型青光眼急性发作的危险因素。

ObjectiveTo investigate the anatomy risk factors of anterior segment and ciliary body by comparing the attack eyes with fellow eyes of primary acute angle-closure glaucoma （PAACG） after complete remission. Method15 cases of PAACG after complete remission and without triad who were treated in Beijing Tongren Hospital, Capital Medical University from January 2015 to December 2015 were enrolled as research objects. Images of anterior segment of attack eyes and fellow eyes were obtained by ultrasound biomicroscope （UBM）. Anterior chamber depth, lens vault, scleral spur distance, ciliary sulcus distance and ciliary body area were measured by Photoshop software and then compared. ResultAnterior chamber depth of attack eyes was significantly shallower than that of fellow eyes （P 〈 0.05）. Lens vault of attack eyes was significantly higher than that of fellow eyes （P〈0.05）. Ciliary body areas （12 o＇clock and 6 o＇clock） of attack eyes were significantly larger than those of fellow eyes （P 〈 0.05）. Scleral spur distance and ciliary sulcus distance showed no significant differences between attack eyes and fellow eyes （P 〉 0.05）. ConclusionRelative forward position of lens and larger ciliary body area may be the risk factors for acute attack of PAACG.
