前节OCT在瞳孔残膜诊治中的应用

The Value of Anterior Segment Optical Coherence Tomography in Persistent Pupillary Membrane

目的:探讨前节OCT在瞳孔残膜诊治中的应用价值。方法:采用光照射与暗光下对12例(24只眼)瞳孔残膜患者进行前节OCT检查,总结其特点,根据检查结果,结合患者年龄、视力、残膜致密形态及致密程度制定治疗方案。结果:瞳孔残膜在OCT检查中表现为高信号,通过光照射与暗光下OCT检查结果的对比,12例(24只眼)瞳孔残膜与晶状体表面均无粘连,8例(16只眼)采用手术切除,4例(8只眼)行激光治疗,治疗后大部分患者视力或视觉质量有不同程度提高。结论:前节OCT能清楚显示瞳孔残膜,根据光照射与暗光下OCT检查可以进一步了解残膜与晶状体表面有无粘连,为治疗方案的选择提供依据,具有一定的临床实用价值。

Objective： To analyze the value of anterior segment optical coherence tomography when diagnose and treat persistent pupillary membrane.Method： 12 cases （ 24 eyes ） of persistent pupinary membrane were underwent anterior segment optical coherence tomography examination both with or without the irradiation of light.Summarize the character of all the resuh.Design the treatment for the patients according to the results of examination as well as patient＇s age, visual acuity and the character of the membrane.Result： It showed a active reflect signal of the patients underwent the AS-OCT examination. It could detect the changes of the membrane under the condition of dark and light. The membranes showed no interfere effect on the movement of the pupils and no contact to the surface of lens. 8 cases （ 16 eyes ） were treated of membrane resection, and 4 cases （ 8 eyes ） underwent radiation treatment. Most of the patients received a better acuity or quantity of visual.Conclusion： AS-OCT can detect the shape of the membranes under the condition of dark and light, and provides information to determine the best chose for the patients in clinical practice.
