白内障超声乳化术后不同原因的浅前房及处理

目的探讨白内障超声乳化术后浅前房的原因、处理方法及预防措施。方法对12例12只眼白内障超声乳化术后浅前房的患者进行观察处理，分析浅前房的原因，提出不同的处理及防护措施。结果12例浅前房病例中，2例为切口裂开，虹膜嵌顿；3例为切口轻度漏水；2例为瞳孔阻滞，5例为单纯脉络膜脱离。切口裂开虹膜嵌顿组予以手术对症处理；切口轻度漏水组予以加压包扎；瞳孔阻滞组用药物散瞳治疗；单纯脉络膜脱离组未予以特殊处理。8例（66．7％）患者术后2m最佳矫正视力均恢复至0．5以上。结论白内障超声乳化术后的浅前房应针对不同的原因予以不同的处理，单纯脉络膜脱离不需特殊处理也可得到较好的恢复；适当的对症处理可以使患者得到较好的视力恢复。

Causes and management of shallow anterior chamber after phacoemulsification

Objective To investigate the causes, management methods and prevention measures of shallow anterior chamber after phacoemulsification. Methods Phacoemulsification was performed in 12 patients （12 eyes）, and shallow anterior chamber after operation was managed. The different causes, management methods and prevention measures were analyzed. Results Shallow anterior chambers were caused by leakage of the incision with iris prolapse in 2 cases, by slight leakage of the incision in 3 cases, by pupillary blocking in 2 cases, and by simple choroidal detachment in 5 cases. Operations to suture incision and manage prolapsed iris were carried out in the leakage and iris prolapse patients. Compression bandaging was managed in the slight incision leakage patients; Medicinal dilation of the pupil was used for the pupillary blocking patients. No medical treatment was used in the simple choroidal detachment patients. Two months after phacoemulsification, 8 patients （66.7 %） obtained best corrected visual acuity of 0.5 or better. Conclusions Different measures should be taken for shallow anterior chamber after phacoemulsification according to different reasons, no medical treatment should be used for the simple choroidal detachment patients; Appropriate management is helpful for good visual rehabilitation.
