Problems solved by technology

[0003] In order to solve the existing problem that there is no objective analysis and evaluation of the quality of human tears, the present invention provides a tear digital imaging and objective analysis system. The analysis system automatically recognizes the tear film rupture process by taking pictures, and records the tear film rupture site and rupture area. and rupture time, to obtain intuitive graphical analysis results

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] attached by figure 1 combined with Figure 4 , attached Figure 5 , attached Image 6 , attached Figure 7 , attached Figure 8 As shown, a tear analysis system includes a main light source (3) near the projection board (2) that illuminates the projection board (2) and projects it on the cornea of ​​the human eye, and the imaging sensor (6) and the sensor lens (5) photograph Image of the projection plate (2) on the cornea. The visual target light source (9) illuminates the visual target plate (8), and the visual target plate (8) is projected on the retina of the human eye (1) to form an image through the visual target imaging lens (7) and the semi-transparent and half-reflective prism (4). The vision fixation effect is achieved so that the imaging sensor (6) can take a clear image of the projection plate (2) on the cornea of ​​the human eye (1). The main light...

Abstract

The present invention discloses a tear digital imaging and objective analysis system. The problem that in the prior art, human eye tear quality cannot be objectively analyzed and evaluated is mainly solved. The tear digital imaging and objective analysis system is characterized in that a projection plate (2), a semi-permeable semi-inverse prism (4), a sensor lens (5) and an imaging sensor (6) are successively arranged on a main optical axis (12). A sighting mark imaging lens (7), a sighting mark plate (8) and a sighting mark light source (9) are successively arranged on a sighting mark optical axis (13). The main optical axis (12) and the sighting mark optical axis (13) are vertically crossed at the center of the semi-permeable semi-inverse prism (4). A main light source (3) is positioned nearby the projection plate (2). A hard driving module (10) is connected with the main light source (3), the sighting mark light source (9) and the imaging sensor (6). A data processing and display module (11) is connected with the hard driving module (10). According to the system, a tear film breakup process is shot and automatically identified, the tear film breakup position, breakup area and breakup time are recorded, and therefore a visual graphical analysis result is obtained. The tear digital imaging and objective analysis system has the characteristics of real-time shooting, objective analysis and automatic tear film quality classification, and the objective diagnostic basis is provided for doctors.

Description

technical field [0001] The invention relates to a tear digital imaging and objective analysis system, in particular to a tear digital imaging and objective analysis system that can assist doctors in diagnosing tear quality, and belongs to the ophthalmic medical industry. Background technique [0002] Dry eye (dry eye) refers to the instability of the tear film and the damage of the ocular surface caused by the abnormal quantity or quality of tears, which leads to a kind of disease of ocular discomfort symptoms, and is the most common ocular surface disease. Since dry eye is a continuous pathological process, and the condition develops continuously from mild to severe, doctors have no objective basis for judging the quality of tears. The severity of dry eye can only be judged subjectively based on experience, which affects the rationality of the dosage and frequency of administration. sex. Therefore, in the field of ophthalmology, there is an urgent need for a device that ca...
