synoptophore
英文介绍
A synoptophore is a specialized ophthalmic instrument mainly used for the examination and treatment of binocular vision function. The following is a detailed introduction:
- Structural composition: The synoptophore is usually composed of two adjustable eyepiece tubes, a base, a mechanical rotation system and a control system. The two eyepiece tubes can present different visual targets to the two eyes respectively, and can be adjusted in terms of position, angle and distance. The base provides a stable support, and the mechanical rotation system enables the eyepiece tubes to rotate horizontally and vertically, simulating the movement of the eyes in different directions. The control system is used to adjust the parameters of visual targets, such as brightness, size, and color.
- Working principle: It is based on the principle of binocular disparity. By presenting different images to the two eyes, it can stimulate the binocular visual function of the human body, so as to detect whether there is a visual function disorder, such as strabismus, amblyopia, and binocular vision dysfunction. At the same time, through specific training programs, it can also be used to improve and restore binocular vision function.
- Clinical applications: The synoptophore is widely used in ophthalmology and optometry. It is an important tool for the diagnosis of strabismus and amblyopia, which can accurately measure the angle of strabismus and evaluate the degree of binocular vision. In addition, it is also used for binocular vision training for patients with visual function disorders, helping them to improve binocular coordination ability, enhance the sense of fusion, and improve the quality of visual function.
中文介绍
同视机是一种专门用于双眼视觉功能检查与治疗的眼科仪器，具体介绍如下：
- 结构组成：同视机通常由两个可调节的目镜筒、底座、机械旋转系统和控制系统组成。两个目镜筒可分别向双眼呈现不同的视标，且能在位置、角度和距离等方面进行调节。底座提供稳定支撑，机械旋转系统可使目镜筒做水平和垂直方向的转动，模拟眼睛在不同方向的运动。控制系统则用于调节视标参数，如亮度、大小、颜色等。
- 工作原理：同视机基于双眼视差原理，通过向双眼呈现不同的图像，刺激人体的双眼视觉功能，从而检测是否存在斜视、弱视、双眼视觉功能障碍等视觉功能异常情况。同时，通过特定的训练方案，还可用于改善和恢复双眼视觉功能。
- 临床应用：同视机在眼科与视光领域应用广泛，是斜视、弱视诊断的重要工具，可精确测量斜视角度，评估双眼视功能程度。此外，它也用于为视觉功能障碍患者进行双眼视觉训练，帮助患者提高双眼协调能力，增强融合感，提升视觉功能质量。
