合并虹膜睫状体囊肿的闭角型青光眼发病因素探讨

目的探讨合并虹膜睫状体囊肿的闭角型青光眼相关发病因素。方法收集有虹膜睫状体囊肿的闭角型青光眼患者35例作为青光眼组,以囊肿合并单纯白内障患者59例作为白内障组,均行UBM及A超检查。结果 94位受检者共检出囊肿202个,青光眼组检出多发性囊肿比例高(61.9%),且多见于颞下象限的虹膜睫状沟和睫状冠。青光眼组囊肿平均大小为(0.5920±0.1151)mm,中央前房深度为(2.267±0.123)mm,平均眼轴长度(23.27±0.85)mm;白内障组分别为(0.4661±0.0946)mm、(2.560±0.214)mm、(24.34±0.42)mm,两组比较差异均有统计学意义(均为P<0.05)。结论较大、多发的囊肿是公认的合并虹膜睫状体囊肿的闭角型青光眼患者发病因素,但是浅前房、小眼球等闭角型青光眼的原发因素也参与了此类闭角型青光眼患者的发病。

Predisposing factors of angle-closure glaucoma with iris-ciliary body cysts

Objective To explore the predisposing factors of angle-closure glaucoma with iris-ciliary body cysts.Methods Thirty-five angle-closure glaucoma patients with iris-ciliary body cysts and 59 cataract patients with iris-ciliary body cysts were enrolled and set as glaucoma group and cataract group.All the patients accepted ultrasound biomicroscopy and A-mode ultrasound examination.Results Two hundreds and two cysts were detected in the 94 patients.The incidence rate of multiple cysts in the glaucoma group(61.9%) was higher than that in the cataract group(42.4%).Iris-ciliary body cysts were usually located in the temporal and inferior,and mostly in the iris-ciliary sulcus and pars plana.The mean diameter of iris-ciliary body cysts of the glaucoma group and cataract group were(0.592 0±0.115 1)mm and(0.466 1±0.094 6)mm,central anterior chamber depth were(2.267±0.123)mm and(2.560±0.214)mm,mean ocular axis length were(23.27±0.85)mm and(24.34±0.42)mm,there were statistical differences(all P<0.05).Conclusion The larger and multiple cysts seem to be the predisposing factors of angle-closure glaucoma patients with iris-ciliary body cysts.However,the primary factors of angle-closure glaucoma,such as shallow anterior chamber and nanophthalmos,also take part in the onset.
