目的:观察闭角型青光眼中虹膜睫状体囊肿的发病情况,虹膜睫状体囊肿与前房轴深、房角的关系。方法:利用超声生物显微镜(UBM)对闭角型青光眼患者740例1057眼进行眼前节检查。结果:闭角型青光眼740例1057眼中检出合并虹膜睫状体囊肿者42例60眼,占被检眼数的5.68%。60眼虹膜睫状体囊肿中虹膜睫状沟囊肿56眼(93.33%),睫状冠囊肿4眼(6.67%);其中单发囊肿33眼(55.00%),多发囊肿27眼(45.00%)。不伴有虹膜睫状体囊肿的患者前房轴深1.16～2.37(平均1.843)mm;合并有虹膜睫状体囊肿的患者前房轴深1.67～2.78(平均2.297)mm。伴有及不伴有虹膜睫状体囊肿的闭角型青光眼患者房角粘连>2个象限的比率分别为66.67%和44.59%。结论:虹膜睫状体囊肿在闭角型青光眼中的发病率较高,多为虹膜睫状沟囊肿,对前房轴深影响不大,但可以增加房角粘连范围,引起闭角型青光眼。

AIM:To observe the incidence of iris and ciliary body cysts in angle-closure glaucoma,and its relationship between anterior chamber depth and anterior chamber angle.METHODS:Ultrasound biomicroscopy(UBM)was used in 740 cases 1057 eyes with angle-closure glaucoma for anterior segment examination.RESULTS:Ciliary body cysts were detected in 42 cases 60 eyes among 740 cases 1057 eyes,accounting for 5.68% in the number of examined eyes.Among the iris and ciliary body cysts of 60 eyes,iris ciliary sulcus cysts were in 56 eyes(93.33%),ciliary crown cyst was in 4 eyes(6.67%);one single cyst was in 33 eyes(55.00%),multiple cysts were in 27 eyes(45.00%).Anterior chamber axis depth in patients with no associated ciliary body cysts was 1.16-2.37mm,an average of 1.843mm;anterior chamber axis depth in patients with iris and ciliary body cyst was 1.67-2.78mm,an average of 2.297mm.Angle adhesion rate of more than two quadrants in patients with angle-closure glaucoma associated with and not associated with ciliary body cysts were 66.67% and 44.59% respectively.CONCLUSION:The ciliary body cysts in angle-closure glaucoma have a higher prevalence,mostly iris cyst in the ciliary sulcus,and have little effect on anterior chamber axis depth,but can increase the adhesion angle range,cause angle-closure glaucoma.
