眼部组织由于特殊的解剖结构和所含色素的多少不同、对光线的吸收和产生反射光强度亦不相同。照射在瞳孔区、球结膜和眼睑界面时,对光线的吸收和反射均有明显的差异、可用光电仪器来测量它们的反射光所发生的光电流。为了配合眼球内异物光电控制定位仪的研制,应用光电流来控制X光机自动拍片。我们对瞳孔区、虹膜区、球结膜及眼睑各部位的反射光所产生的光电流量进行检测。材料与方法所选择的对象为汉族52人、102只正常眼(男52只、女52只)、年龄5～49岁,平均年龄26、26岁(见表1)视力均在1.0以上。眼睑和球结膜均五色素沉着、色素痣、
Eye tissue due to the special anatomy and pigment contained in the number of different, the absorption of light and produce the reflected light intensity is not the same. Irradiation in the pupil area, conjunctival and eyelid interface, the light absorption and reflection were significantly different, the photoelectric instrument can be used to measure their reflected light by the photocurrent. In order to cooperate with the development of ophthalmic foreign object positioning control instrument, the application of photocurrent to control the X-ray machine automatic filming. We detect the pupil area, iris area, conjunctiva and eyelid parts of the reflected light generated by the photocurrent. Materials and Methods The selected subjects were 52 Han people, 102 normal eyes (52 males and 52 females), aged 5 to 49 years, with an average age of 26,26 years (Table 1) visual acuity of 1.0 or more. Eyelids and conjunctiva were five pigmentation, pigmented nevus,
