Problems solved by technology

[0005] 1. The method of observing the fluorescein-stained cornea based on the slit lamp depends on the experience of the physician and the stability of the dye to the tear film. The inspection results are highly subjective and unstable. Before the inspection, the patient needs to instill the dye. cause certain harm to patients;
[0006] 2. The test method of tear secretion lasts for a long time, and the invasion of the test paper will bring some discomfort to the patient. The test result may be affected by the tears produced by the test paper invasion and reduce the accuracy;
[0007] 3. Keratograph 5M equipment is large in size and poor in portability;
[0008] 4. Keratograph 5M is an integrated device, which is not suitable for the examination of lying patients;
[0009] 5. The Keratograph 5M equipment structure is not compatible with the current ophthalmic examination equipment and takes up more space and resources

Embodiment 1

[0043] like figure 1 What is shown is an implementation form according to the present invention, which includes: an imaging system for taking pictures of patients' eyes, an analysis system for analyzing multiple symptoms on the images, and a video terminal for displaying the images.

[0044] In the present invention, the imaging system is arranged in an integrated probe assembly 4, such as figure 2 As shown, the probe assembly includes an imaging assembly, an illumination light source 44, a camera module 45, and a control board 47 arranged in sequence. The imaging assembly, the illumination light source 44, and the camera module 45 are fixed on one side of the camera fixture 46. The control board 47 is fixed on the other side of the camera fixing device 46, and at the same time, it is closed into a complete structure with a cover plate 48. The imaging assembly includes a tapered tube 41, a fixing sleeve 42 and an optical filter 43 arranged in sequence. The fixing sleeve 42 i...

Embodiment 2

[0052] On the basis of Example 1, as figure 2 As shown, a baffle 411 is arranged laterally on the flat bottom end of the conical cylinder 41, and a positioning groove 421 is opened on the small opening of the light collecting cavity. In order to meet different detection functions, it is necessary to switch the imaging mode, so It is necessary to remove the tapered cylinder 41 from the fixed sleeve. For this reason, in this embodiment, the tapered cylinder 41 is detachably mounted on the fixed sleeve 42, and the blocking piece 411 is clamped on the fixed sleeve. In the positioning groove 421, the Placido cone is designed to be removed during use to meet the needs of different functional imaging.

Embodiment 3

[0054] On the basis of Embodiment 1 or Embodiment 2, the inner wall of the light-gathering cavity is coated with a diffuse reflection coating, and the outgoing light of the illumination source is evenly reflected to the cone through the diffuse reflection coating. The conical surface of the tube gathers the outgoing light to the conical surface of the conical tube, which enhances the effectiveness of the irradiated light, reduces polarized light and light leakage, so that the outgoing light is concentrated on the patient's eyes, providing better lighting effect, and further Improve the imaging effect and improve the accuracy, objectivity and stability of the measurement results.

Abstract

The invention discloses a comprehensive analysis system for xerophthalmia. The comprehensive analysis system comprises an imaging system, an analyzing system and a video terminal, wherein the imaging system comprises a lighting source, an imaging assembly, a control panel and a camera shooting module, the lighting source penetrates through the imaging assembly and irradiates the eyes of a patient, and the camera shooting module carries out imaging on the eyes of the patient, and transmits the generated image to a PC machine through a USB interface; the analyzing system is arranged at the PC machine end, and comprises a communication module, an image data collecting module, a tear film breakup time check module, a lacrimal rivus height measuring module, a meibomian gland image collecting and enhancing module, a lipid layer analyzing module, a data analyzing module and an information management output module; the video terminal is connected with the analyzing system. With the comprehensive analysis system for xerophthalmia provided by the invention, the functions of tear film breakup time statistics checking, lacrimal rivus height measurement, meibomian gland image collection and enhancement, human eye lipid layer analysis, and the like are realized, a basis is provided for the clinical diagnosis for xerophthalmia, and the comprehensive analysis system is applied to the medical treatment in the relevant fields of clinical diagnosis of the ophtalmology department.

Description

technical field [0001] The invention relates to a dry eye syndrome detection device, in particular to a dry eye syndrome comprehensive analysis system. Background technique [0002] Dry eye refers to the general term for various diseases characterized by abnormal tear quality and quantity or dynamic abnormalities caused by any reason, accompanied by ocular discomfort, resulting in various diseases characterized by ocular surface tissue lesions. Conjunctival xerosis. Common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, burning sensation, sticky secretions, fear of wind, photophobia, and sensitivity to external stimuli. A survey in the United States shows that 10%-15% of adults suffer from dry eye, 17% in Japan, 10.3% in Australia, and the prevalence of dry eye in my country is about 21%-33.7%. The incidence of dry eye is increasing year by year. With the widespread use of electronic screens, environmental degradation, abuse of eye drops, wearin...
