应用超声生物显微镜与房角镜检查眼前房角结果的比较

目的 比较应用超声生物显微镜（ｕｌｔｒａｓｏｕｎｄｂｉｏｍｉｃｒｏｓｃｏｐｙ,ＵＢＭ）与房角镜检查眼前房角的结果,为房角镜检查提供新的技术和资料。方法 采用双盲法分别对１０例（２０只眼）的眼前房角进行超声生物显微镜和裂隙灯显微镜房角镜检查。并将两种检查结果进行比较,采用等级相关法对获取的资料和结果进行统计学分析,（取α＝０．０５）。结果,两种检查法在宽房角状态下对房角的检查结果有较好的一致性, 在

Comparison of results of chamber angle examination by ultrasound biomicroscopy and gonioscopy

Objective To compare the consistency of the chamber angles examined by ultrasound biomicroscope (UBM) and gonioscope and provide gonioscopic examination with new methods and technology. Methods 10 patients (20 eyes) were selected for the research. The same eyes were examined by UBM and gonioscope in turns. The results from the two methods were compared and the data were analyzed with Spearman correlation test. Results The results of two methods of chamber angle examination were well consistent when the angle was wide, but the consistency was not good when it was narrow. The angle examined by a gonioscope was wider than that by UBM. When the iris root insertion was evaluated in a narrow angle, the consistency was also not good, and when the peripheral iris morphology was evaluated, there were almost inconsistent results in onefourth of the patients. Conclusions The results of chamber angle examined by a gonioscope show a little wider than its natural status. Especially, it is difficult to distinguish the functional closure from the adhesive closure. Under the influence of light, the determination of iris root insertion by a gonioscope has a sense of conjecture. When peripheral iris morphology is evaluated, the influence of irregular iris might result in a wrong conclusion. Therefore, the technique of gonioscopic examination should be improved.
