Problems solved by technology

Usually, only one parameter can be measured by one diagnostic test, and multiple diagnostic tests must be combined to obtain multiple parameters indicative of dry eye syndrome. It takes a long time to perform multiple diagnostic tests and the process is cumbersome, and most of the diagnoses must be done manually by doctors , the repeatability and objectivity of diagnostic results largely depend on the experience of physicians, and some invasive diagnostic items are likely to bring discomfort to patients

Embodiment Construction

[0026] The present invention will be further described below through specific embodiments.

[0027] Such as figure 1 As shown, a comprehensive diagnostic instrument for dry eye syndrome includes a host computer, a controller 5, a Placido plate 1, a near-infrared light illumination system 4, a white light illumination system 2 behind the Placido plate 1, and an imaging system connected to the host computer 3. The imaging system 3 is located behind the white light illumination system 2 and includes an industrial camera 33 , an autofocus lens 31 , a filter wheel 32 , a motor 34 and a gear 35 . An infrared cut-off filter 321 and an infrared filter 322 are installed on the filter wheel 32, the filter wheel 32 is located between the industrial camera 33 and the autofocus lens 31, and meshes with the gear 35, and the motor 34 passes through the gear 35 can drive filter wheel 32 to rotate, as figure 2 shown. The motor 34 is connected with the controller 5, and the host computer c...

Abstract

The invention relates to a comprehensive diagnostic apparatus for xerophthalmia. The comprehensive diagnostic apparatus comprises an upper computer, a controller, a Placido disc, a near-infrared light illuminating system, a white light illuminating system, and an imaging system, wherein the white light illuminating system comprises a diffuse reflection plate and a white light LED array, the imaging system comprises an industrial camera, an automatic focusing lens, an optical filter wheel disc, a motor and a gear, the diagnostic apparatus respectively measures the tear meniscus height, the area of a tiny blood vessel of a conjunctiva, the structural and morphological parameters of meibomian glands, the breakup time of a tear film, and the thickness of a lipid layer of the tear film according to the principles of visible light / near-infrared light imaging measurement, structured light imaging measurement and white light interferometry, so as to provide objective diagnostic evidences and preliminary diagnostic result for the diagnosis of the xerophthalmia. The diagnostic apparatus can replace a series of separated diagnosis items during the clinical diagnosis of the xerophthalmia, the diagnosis flow of the xerophthalmia is simplified, the diagnosis time is shortened, and the objectivity and the repeatability of the diagnosis result are improved.

Description

technical field [0001] The invention relates to a non-contact dry eye diagnosis instrument, which can provide objective diagnosis basis for the diagnosis of dry eye and provide preliminary diagnosis results. Background technique [0002] Dry eye, also known as keratoconjunctival sicca, refers to a class of diseases that cause ocular discomfort symptoms due to the incompleteness and damage of the tear film caused by the abnormal amount or quality of tears. A stable tear film is the basis for maintaining the health of the ocular surface, which depends on the normal quantity and quality of the layers that make up the tear film and the normal tear dynamics. Any factors that affect the stability of the tear film will cause dry eye syndrome. In the modern lifestyle, the widespread use of air conditioners, computers, and televisions and the aggravation of air pollution have led to a gradual increase in the incidence of dry eye disease, and more and more attention has been paid to t...
