方法：对457眼青光眼滤过性手术后发生脉络膜脱离的42眼患者进行回顾性分析和总结。

结果：脉络膜脱离发生时间为术后3～7(平均4.51±1.14)d，患者的平均年龄为65.30±3.50岁。通过皮质类固醇类药物、散瞳、高渗剂等治疗，42眼脉络膜脱离全部恢复。治疗所需时间平均为16.50±2.75d。

结论：脉络膜脱离是青光眼滤过性手术后的一个常见并发症，与术前眼压控制不好、术后眼压过低、患者年龄偏大及高血压、糖尿病有关。

METHODS: The clinical data of 42 eyes with choroidal detachment of 457 eyes undergoing glaucoma filtering were retrospectively analyzed.

RESULTS: Choroidal detachment occurred at 3-7 days after glaucoma filtering surgery, with mean 4.51±1.14 days. The patient's average age was 65.30±3.50 years. Chroidal detachment was reformed by corticosteroids medicine mydriatic drugs hypertonic agent and all recovered, within 16.50±2.75 days.

CONCLUSION: Chroidal detachment is a common complication of glaucoma filtering surgery. The related factors include high intraocular pressure and eyeball congestion before surgery, postoperative low intraocular pressure, diabetes, hypertension and the aged.
