Problems solved by technology

[0008] Although the above test methods are often used to establish the diagnosis of dry eye syndrome, placing the filter paper on the lower eyelid is quite invasive to the eyes, which will cause the patient's sense of fear and the chance of bacterial infection, and the test process will take a long time. Dozens of minutes also cause obvious discomfort to the patient; and because the BUT test must titrate the dye, it also causes discomfort to the patient, and it is very dependent on the patient's cooperation ability
In addition to making patients feel fear and discomfort, the above two inspection methods also have disadvantages such as low repeatability and high variability.

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0040] Such as figure 1 As shown, the system schematic diagram of a feasible embodiment of the present invention includes a fixed frame 10 for the patient's head to rely on, an infrared thermal imager 20 and a conversion unit (not shown in the figure), and the infrared thermal imager 20 is transparent Connect with a computer system (not shown in the figure) through this conversion unit; Wherein:

[0041] The fixed frame 10 is provided with an upper forehead support plate 12 and a lower jaw support 13 at the upper and lower ends of the two parallel vertical rods 11, which are used for the patient to rest on his head during examination. The head then leans against the upper forehead resting plate 12, except that the head is fixed, and also facilitates its line of sight towards a specific direction.

[0042] The infrared thermal imaging camera 2...

Abstract

The invention discloses a device for judging the eye disease (including xerophthalma) and method thereof of application. The image at the front surface of the eyeball of patient suffered from eye disease is shot by a infra-red thermograph and the precise temperature variation of cornea special position is traced in unit time, and the K value of cooling curve and cooling temperature difference delta T are obtained according to temperature difference in time sequence, the curve of K value and delta T value is maximized to help the doctor judge the diseases of the eye. The said device and method has features of non-invasion, high repeatability and low mutation, the patient needs not induce the fear resulted from the filter paper or stain into eyes and uncomfortable feeling and danger of infecting the bacteria because of direct contact, so that the invention provides convenience and high accuracy.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a device for judging eye diseases, in particular to a technology for using an infrared thermal imager to capture temperature changes on the anterior surface of a patient's eyeball as a basis for judging eye diseases (including dry eye). Background technique [0002] The human eye has a tear film on the surface of the cornea that protects a mucus layer, a water layer, and an oily layer from the inside to the outside, thereby forming a complete tear layer; the oily layer on the front surface of the eyeball is composed of The meibomian glands secrete and form, the middle aqueous layer is produced by the lacrimal gland and accessory lacrimal gland, and the inner mucus layer is mainly produced by the goblet cells of the conjunctiva. The three functions complement each other, among which the function of the oily layer is to prevent the evaporation of water, and the mucus layer can make t...
