【摘要】：目的 研究對(duì)晶體后囊膜這一解剖位置在Oculus pentacam前節(jié)分析系統(tǒng)應(yīng)用觀察中的準(zhǔn)確性,確定預(yù)防和治療PCO的方法和時(shí)間段。 方法 借助設(shè)備鷹視眼前節(jié)分析系統(tǒng),是由德國(guó)Oculus pentacam系統(tǒng)研制的眼科檢查和眼病診斷儀器。應(yīng)用Oculus pentacam眼球前節(jié)分析系統(tǒng),通過(guò)動(dòng)物實(shí)驗(yàn)確定本系統(tǒng)的測(cè)量準(zhǔn)確可信度,應(yīng)用于對(duì)臨床白內(nèi)障術(shù)后(PCO)病人的囊膜厚度、密度的變化并做動(dòng)態(tài)觀測(cè)。 結(jié)果 前節(jié)分析儀囊膜厚度三維可視圖的建立與光鏡及透射電鏡檢查評(píng)價(jià),PCO個(gè)體間可信度檢驗(yàn)的標(biāo)準(zhǔn)差、非參數(shù)分析顯示差異無(wú)統(tǒng)計(jì)學(xué)意義、個(gè)體內(nèi)可信度檢驗(yàn)的標(biāo)準(zhǔn)差、差異也無(wú)統(tǒng)計(jì)學(xué)意義；兩種PCO定量分析方法的比較研究實(shí)驗(yàn)結(jié)果顯示在晶狀體前后囊膜接近赤道部,晶體囊膜的厚度、密度及同一PCO三維可視圖像的評(píng)價(jià)之間具有直接的相關(guān)性；前節(jié)分析儀囊膜厚度三維可視圖與光鏡掃描及透射電鏡掃描發(fā)生PCO的晶體后囊厚度、密度無(wú)明顯差異(p0.05)。 結(jié)論 眼前節(jié)分析系統(tǒng)可提供清晰的PCO影像和多個(gè)眼前節(jié)分析數(shù)據(jù),是動(dòng)態(tài)評(píng)估晶體囊膜厚度變化的有效手段。采用Pentacam三維眼前節(jié)分析儀針對(duì)白內(nèi)障手術(shù)后PCO渾濁過(guò)程厚度、密度發(fā)展的動(dòng)態(tài)觀察研究具有可信、準(zhǔn)確、無(wú)創(chuàng)、簡(jiǎn)便的優(yōu)點(diǎn),可以確定預(yù)防和治療的時(shí)間段以及治療方法。同時(shí)可以對(duì)人工晶狀體在眼內(nèi)的穩(wěn)定性,及其對(duì)手術(shù)后晶體囊膜的厚度、密度的影響做動(dòng)態(tài)觀察。
[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.
