dry – eye detector
中文介绍
干眼检测仪是一种用于检测和评估干眼状况的医疗设备。它通常基于多种技术原理，可对泪液分泌、泪膜稳定性、眼表上皮完整性等干眼相关指标进行检测。
干眼检测仪的检测功能多样。一方面，它可通过泪液分泌试验，如 Schirmer 试验，利用特殊的试纸来测量泪液在一定时间内的分泌量，判断患者是否存在泪液分泌不足的情况。另一方面，能借助红外成像或荧光染色等技术，观察泪膜的破裂时间，评估泪膜的稳定性，若泪膜破裂时间过短，说明泪膜稳定性差，是干眼的重要特征之一。此外，部分干眼检测仪还可通过荧光染色或共聚焦显微镜技术，观察眼表上皮细胞的形态和完整性，若上皮细胞出现损伤、脱落等情况，也提示可能存在干眼。
干眼检测仪在眼科临床中应用广泛。它能为干眼的诊断提供客观依据，帮助医生准确判断干眼的类型和严重程度，以便制定个性化的治疗方案。同时，也可用于治疗过程中的疗效监测，让医生及时了解治疗效果，调整治疗策略，对于改善干眼患者的眼部症状和提高生活质量具有重要意义。
英文介绍
Dry – eye detector is a medical device used to detect and evaluate the condition of dry eye. It is usually based on a variety of technical principles, and can detect dry – eye related indicators, such as tear secretion, tear film stability, and the integrity of the ocular surface epithelium.
Dry – eye detectors have diverse detection functions. On the one hand, it can measure the tear secretion volume within a certain period through the tear secretion test, such as the Schirmer test, using special test paper to determine whether the patient has insufficient tear secretion. On the other hand, it can observe the tear – film break – up time by means of infrared imaging or fluorescence staining technology to evaluate the stability of the tear film. If the tear – film break – up time is too short, it indicates poor tear – film stability, which is one of the important characteristics of dry eye. In addition, some dry – eye detectors can also observe the morphology and integrity of ocular surface epithelial cells through fluorescence staining or confocal microscopy technology. The damage and shedding of epithelial cells also suggest the possible existence of dry eye.
Dry – eye detectors are widely used in ophthalmic clinics. They can provide an objective basis for the diagnosis of dry eye, helping doctors accurately determine the type and severity of dry eye, so as to formulate personalized treatment plans. At the same time, they can also be used for the monitoring of treatment effects during the treatment process, enabling doctors to timely understand the treatment effect and adjust the treatment strategy, which is of great significance for improving the ocular symptoms and quality of life of dry – eye patients.
