Dry eye disease full-automatic detecting apparatus

Abstract

The invention discloses a dry eye disease full-automatic detecting apparatus, which comprises a probe assembly, a handle, a portable device and an analysis device, wherein the probe assembly comprises an imaging assembly, a lighting source, a camera module, a camera fixing device, a control board and a cover plate; the imaging assembly comprises an optical filter, a fixed sleeve and a conical drum; the conical drum is of an annular structure chequered with black and white; black rings are formed by conducting silk-screen printing with oil ink, and the oil ink is transmissive in infrared light and is non-transmissive in white light; one end of the handle is connected to the lower end of the probe assembly; the portable device comprises a base, a head supporting assembly, an adjusting handle rod and an adjustable workbench assembly; and the analysis device comprises an image data acquisition unit, a data detection unit and a data analysis unit. According to the detecting apparatus provided by the invention, the black annular structures on the conical drum is invisible to some infrared light while is visible to the white light, so that the demands of four imaging modes are satisfied; and it is unnecessary to detach the Placido conical drum when the detecting apparatus is used, so that a using process is simplified and the conical drum is prevented from getting lost easily.

Description

technical field [0001] The invention relates to a dry eye syndrome detection device, in particular to a dry eye syndrome automatic detection instrument. 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, weari...

The traditional tear film break-up time (BUT) test is the time when the first dry spot appears on the cornea under a slit lamp microscope after corneal fluorescein sodium staining. The accuracy of the test results depends on the experience of the observer and the effect of the stain on the tear film. Stability; tear secretion test uses standard test paper for tear measurement, gently put two standard test papers into the junction of the middle and outer 1 / 3 of the conjunctival sac under the test eye, the patient looks down or gently closes the eyes, and removes the test paper after 5 minutes , read the scale of the test paper after leaving it for one minute, and judge the diagnosis result according to the test value. This method can also test the basic value under the state of surface anesthesia of the patient, so as to avoid the tear secretion caused by the stimulation of the test paper itself from affecting the accuracy of the test result. The test method is also one of the commonly used methods in clinical ophthalmology at present. The cost is low, but the test process lasts for a long time, and the invasive method brings some discomfort to the patient; Keratograph5M can comprehensively analyze dry eye symptoms, but the equipment is relatively large , poor portability, high cost, poor popularity

[0004] At the same time, the black stripe part of the Placido ring in the imaging component of the existing dry eye analyzer is printed with ordinary ink. After the tear film breakup time is measured, the Placido cone needs to be removed, and then the tear river height measurement, lipid layer image For acquisition and meibomian gland image acquisition, the Placido cone needs to be installed again after the three measurements are completed. This design mode will undoubtedly bring some trouble to the operator, and the Placido cone is easy to lose after it is removed.
