中文介绍
眼睑接触式电子眼压计是一种用于测量眼压的专业眼科设备。它通过与眼睑接触来获取眼压数据，是眼压测量领域的重要工具，对于青光眼等眼部疾病的诊断和监测意义重大。
- 结构与原理：通常由眼压传感器、信号处理单元、显示装置等部分构成。眼压传感器是关键部件，当它与眼睑轻轻接触时，能感应到眼球内部压力对眼睑产生的作用力，并将其转化为电信号。信号处理单元会对这些电信号进行分析和处理，再通过复杂的算法计算出眼压数值，最后在显示装置上直观呈现给医护人员。
- 特点优势：相比传统眼压测量方法，这种眼压计具有独特优势。首先，它无需直接接触角膜，减少了交叉感染的风险，同时也避免了因角膜表面麻醉剂使用不当可能引发的问题。其次，测量过程相对舒适，患者更容易接受，尤其适用于儿童、老年人以及对传统眼压测量方式较为敏感的人群。此外，其测量结果较为准确可靠，能够为医生提供有价值的临床数据。
- 临床应用：在眼科临床工作中，主要用于青光眼的筛查和诊断。青光眼患者眼压通常会高于正常水平，定期使用眼睑接触式电子眼压计测量眼压，有助于医生及时发现眼压异常变化，制定个性化的治疗方案。同时，对于其他可能影响眼压的眼部疾病，如眼外伤、葡萄膜炎等，该眼压计也可辅助医生进行病情监测和评估。
英文介绍
The eyelid contact electronic tonometer is a professional ophthalmic device used to measure intraocular pressure. It obtains intraocular pressure data by contacting the eyelid and is an important tool in the field of intraocular pressure measurement, which is of great significance for the diagnosis and monitoring of eye diseases such as glaucoma.
- Structure and Principle: It usually consists of components such as an intraocular pressure sensor, a signal processing unit, and a display device. The intraocular pressure sensor is a key component. When it gently contacts the eyelid, it can sense the force exerted on the eyelid by the pressure inside the eyeball and convert it into an electrical signal. The signal processing unit analyzes and processes these electrical signals, calculates the intraocular pressure value through complex algorithms, and finally presents it intuitively to medical staff on the display device.
- Features and Advantages: Compared with traditional intraocular pressure measurement methods, this tonometer has unique advantages. Firstly, it does not need to directly contact the cornea, reducing the risk of cross – infection and avoiding potential problems caused by improper use of corneal surface anesthetics. Secondly, the measurement process is relatively comfortable, making it more acceptable to patients, especially children, the elderly, and those who are sensitive to traditional intraocular pressure measurement methods. In addition, its measurement results are relatively accurate and reliable, providing valuable clinical data for doctors.
- Clinical Applications: In ophthalmic clinical practice, it is mainly used for the screening and diagnosis of glaucoma. The intraocular pressure of glaucoma patients is usually higher than normal. Regular measurement of intraocular pressure with an eyelid contact electronic tonometer helps doctors detect abnormal changes in intraocular pressure in a timely manner and develop personalized treatment plans. At the same time, for other eye diseases that may affect intraocular pressure, such as eye trauma and uveitis, this tonometer can also assist doctors in disease monitoring and evaluation.
