前房深度的测量方法有多种,国内文献也有几种测量方法,其测定值也不一致,许多方法都藉光投射焦点的移动来观测角膜与晶状体之间的差距来计算,而移动焦点时,每因被检者的轻微移动、呼吸和血管搏动而影响测量数值。近年来虽有装在裂隙灯上的前房深度测量仪来测量前房深度使准确性提高,但目前国内尚无生产,不易推广。我科设计的利用显微镜微测计直接测定裂隙灯的裂隙长度,仿Smith氏法无须移动焦点,测量正常青少年27人54只眼的结果来看,其数值同近两年来国
There are many ways to measure the depth of the anterior chamber, there are several measurement methods in the domestic literature, and the measured values are not the same. Many methods calculate the difference between the cornea and the lens by the movement of the light projection focus. When moving the focus, Each measurement is affected by slight movement of the subject, respiration and pulsation of the blood vessels. Although in recent years installed in the slit lamp on the depth of the anterior chamber depth measuring instrument to measure the depth of accuracy to improve accuracy, but at present there is no production, not easy to promote. Our department designed the use of microscope micro-measurement directly measure the slit lamp slit length, imitation Smith’s method without moving the focus, the measurement of normal adolescent 27 54 eyes of the results of view, its value with the past two years
