| 摘 要： | 本文介绍了两扇门式映光检影法,它是用电检影镜测定屈光不正的一种他觉方法。检查者用球镜去中和病人瞳孔区的映光,直到两扇门映光的大小、亮度和移动速度变成几乎一致,并在两扇门映光之问条状黑裂隙的正中出现一个角膜反光点时,那就找到了中和点。本文并对有关检影技术的注意点进行了讨论。

| Abstract: | The author's retinoscopy with a double-door type of illumination is presented in this paper. It is an objective method for the measurement of refractive errors by using an elect ic retinoscope. Spherical lens are used to neutralize the illumination from the pupil of the Patient u til the size, intensity and rapidity of movement of the double-door illumination from the pupil becomes almost identical. When a lineal back slit srace has been revealed in the middle of the double-door illumination, with a point of re(?)lex light on the center corneal surface, the neutral point is determined. The main points of using this method are also discussed in this paper. |
