Description

The full-automatic detector of xerophthalmia

Technical field

It the utility model is related to a kind of xerophthalmia detection device, particularly a kind of full-automatic detector of xerophthalmia.

Background technology

Xerophthalmia refers under tear quality and quantity exception caused by any reason or the extremely caused tear film stability of dynamics Drop, and with ophthalmic uncomfortable, cause the general name for a variety of diseases that ocular lesion tissue is characterized, also known as angle xerosis of conjunctiva.Often See symptom include eyes it is dry and astringent, easily tired, eye itch, have sticky foreign body sensation, pain burning heat sensation, secretion, fear of wind, photophobia, externally Boundary stimulates very sensitive.One investigation in the U.S. shows that 10%-15% adult suffers from dry eyes, and Japan is 17%, Australia For 10.3%, the dry eyes illness rate in China is about in 21%-33.7%, and the incidence of disease of dry eyes worldwide is on year by year at present The trend of liter, with the reasons such as the widely using of electronic curtain, the wearing of the abuse of environmental degradation, eye drops, contact lenses, dry eyes Disease will also continue to increase, and clinician is badly in need of a kind of quick, portable, contactless, objective, quantitative, comprehensive xerophthalmia of intelligence Analytical equipment auxiliary diagnosis.Lacked according to the class of pathological characteristics dry eyes classification two, including lipid shortage type dry eyes (LTD) and aqueous Weary type dry eyes (ATD).The utility model can make comprehensive analysis result to xerophthalmia class, and auxiliary doctor is for different type and not Dry eyes with degree formulate individualized treatment scheme, improve therapeutic effect, reduce patient suffering.

Currently used xerophthalmia detection method mainly includes the breakup time of tear film detection of intrusive mood, Schimer's test (such as Schirmer I and II experiment), slit lamp examination and German OCULUS Keratograph 5M for releasing recently etc..Tradition Breakup time of tear film (BUT) detection be corneal fluorescein sodium dyeing after under slit-lamp microscope observe cornea occur first Dry the time of spot, inspection result accuracy dependent on observer experience and coloring agent to the stability of tear film；Lacrimal secretion Experiment carries out tear measurement using standard testing strips, and the China and foreign countries 1/3 that two standard testing strips are gently put into conjunctival sac under tested eye are handed over At boundary, patient is looked down or gently closed one's eyes, and test paper is removed after 5 minutes, test paper scale is read after placing one minute, according to test value Judge diagnostic result, this method can also drip in patient tests basic value with surface anesthesia state, avoids test paper from stimulating in itself and leads The lacrimal secretion of cause influences the accuracy of result of the test, Schimer's test method be also the conventional method of current Clinical Ophthalmology it One, cost is low, but the test process duration is grown, and the method for intrusive mood brings certain sense of discomfort to patient；Keratograph 5M can more fully analyze dry eye condition, but the equipment is larger, and portability is poor, and cost is higher, and popularization is bad.
