【摘要】：目的研究对晶体后囊膜这一解剖位置在Oculus pentacam前节分析系统应用观察中的准确性,确定预防和治疗PCO的方法和时间段。方法借助设备鹰视眼前节分析系统,是由德国Oculus pentacam系统研制的眼科检查和眼病诊断仪器。应用Oculus pentacam眼球前节分析系统,通过动物实验确定本系统的测量准确可信度,应用于对临床白内障术后(PCO)病人的囊膜厚度、密度的变化并做动态观测。结果前节分析仪囊膜厚度三维可视图的建立与光镜及透射电镜检查评价,PCO个体间可信度检验的标准差、非参数分析显示差异无统计学意义、个体内可信度检验的标准差、差异也无统计学意义；两种PCO定量分析方法的比较研究实验结果显示在晶状体前后囊膜接近赤道部,晶体囊膜的厚度、密度及同一PCO三维可视图像的评价之间具有直接的相关性；前节分析仪囊膜厚度三维可视图与光镜扫描及透射电镜扫描发生PCO的晶体后囊厚度、密度无明显差异(p0.05)。结论眼前节分析系统可提供清晰的PCO影像和多个眼前节分析数据,是动态评估晶体囊膜厚度变化的有效手段。采用Pentacam三维眼前节分析仪针对白内障手术后PCO浑浊过程厚度、密度发展的动态观察研究具有可信、准确、无创、简便的优点,可以确定预防和治疗的时间段以及治疗方法。同时可以对人工晶状体在眼内的稳定性,及其对手术后晶体囊膜的厚度、密度的影响做动态观察。
[Abstract]:PurposeTo study the accuracy of the anatomical position of posterior capsule of lens in the application of Oculus pentacam anterior segment analysis system, and to determine the method and time period of prevention and treatment of PCO.MethodWith the aid of the Eagle anterior segment analysis system, an ophthalmic examination and ophthalmic diagnosis instrument was developed by Oculus pentacam system in Germany.The Oculus pentacam anterior segment analysis system was used to determine the accuracy and reliability of the system through animal experiments. The changes of the thickness and density of capsule in patients with clinical cataract after cataract surgery were observed dynamically.ResultThe establishment of 3D visual image of capsule thickness of anterior segment analyzer and the evaluation of the standard deviation of reliability test among individuals by light microscope and transmission electron microscope showed that there was no significant difference in nonparametric analysis, but the standard deviation of confidence test in vivo was not significant.There was no significant difference between the two PCO quantitative methods. The experimental results showed that the anterior posterior capsule was near the equator and the thickness of the lens capsule.There was a direct correlation between the density and the evaluation of the same PCO 3D visual image, and there was no significant difference in the thickness of the posterior capsule of PCO between the 3D visual image of the anterior segment analyzer and the scanning of light microscope and transmission electron microscope.ConclusionThe anterior segment analysis system can provide clear PCO images and multiple anterior segment analysis data. It is an effective method to dynamically evaluate the thickness of lens capsule.The dynamic observation of the thickness and density of PCO turbid process after cataract surgery by using Pentacam three-dimensional anterior segment analyzer has the advantages of reliable, accurate, non-invasive and simple, and can be used to determine the time period of prevention and treatment as well as the treatment method.The stability of intraocular lens and its effect on the thickness and density of lens capsule after surgery can be observed dynamically.
