[目的] 深肤色人种应用常规散瞳液常难使瞳孔满意地迅速散大,故以机械刺激角膜的方法,以观察对增强药物散瞳效果的作用。[方法] 受试者共8人,黑人、白人各半。角膜麻醉3min后,用压平眼压计测量2名黑人和2名白人之1眼的眼压,触及角膜5s;其余4人各1眼作角膜反射试验。将棉签沿水平方向轻轻擦拭一下角膜缘,长约5mm。眼压计和棉签触擦处裂隙灯下唯一可见的即刻改变,是稀薄的荧光彩点。对侧
[Objective] To apply the conventional mydriasis liquid to dark-skinned people is often difficult to diffuse the pupil satisfactorily. Therefore, the method of mechanically stimulating the cornea is used to observe the effect of enhancing the mydriatic effect of the drug. [Methods] A total of 8 subjects, black, white half. After 3 minutes of corneal anesthesia, the intraocular pressure (IOP) of 1 black and 2 white people was measured with a flattened tonometer, and the cornea was touched for 5 seconds. The other 4 eyes were examined with corneal reflex. Swab gently swab the swab in the horizontal direction for about 5 mm. The only visible immediate change under the slit lamp at the tonometer and the swab contact is the thin, fluorescent color spot. Opposite side
