大型弱视镜是双眼视机能检查及治疗双眼视机能异常不可缺少的器械。我们参阅了国内外有关资料,在缺乏实物对照的情况下,自行设计、研制了一台大型弱视镜(图1)。经临床试用,证明其使用方便,容易掌握,兹将器械构造,性能操作方法及临床应用等项,分述如下: 一、器械构造及性能: 1、底座:系铸钢件制作的坚实金属箱。底座上分别有两金属臂。臂上各连接有镜筒。臂与底座连接处有刻度盘,能标明镜筒内、外转动之度数,二镜筒分别能内转50°,外转50°。两镜筒间的距离及回
Large-scale amblyopic vision binocular vision is the ability to check and treat binocular vision abnormalities indispensable equipment. We refer to the relevant information at home and abroad, in the absence of physical control, to design and develop a large-scale amblyopic sight (Figure 1). Clinical trial to prove its ease of use, easy to grasp, the instrument structure, performance methods of operation and clinical application of the items are as follows: First, the device structure and performance: 1, the base: the Department of solid steel castings made of steel . There are two metal arms on the base. Each arm connected to the lens barrel. Arm and base connection at the dial, can identify the barrel inside and outside the degree of rotation, the second tube were able to turn 50 °, outside the rotation of 50 °. The distance between the two tubes and back
