Description
Technical field
The present invention relates to a kind of xerophthalmia detection device, especially a kind of portable xerophthalmia detector.
Background technique
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, the general name for a variety of diseases for causing ocular lesion tissue to be characterized, also known as angle xerosis of conjunctiva.Often
See symptom to include that eyes are dry and astringent, are easy tired, eye itch, have sticky foreign body sensation, pain burning heat sensation, secretion, fear of wind, photophobia, externally
Boundary's stimulation is very sensitive.The adult of one investigation display 10%-15% in the U.S. suffers from dry eyes, and Japan is 17%, Australia
It is 10.3%, the dry eyes illness rate in China is about in 21%-33.7%, and the disease incidence of dry eyes worldwide is on year by year at present
The trend of liter, with the reasons such as being widely used 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.It is lacked according to two class of pathological characteristics dry eyes classification, including lipid shortage type dry eyes (LTD) and aqueous
Weary type dry eyes (ATD).Analysis comprehensively can be made to xerophthalmia class by the present invention as a result, auxiliary doctor is for different type and different journeys
The dry eyes of degree formulate individualized treatment scheme, improve therapeutic effect, reduce patient suffering.
Currently used xerophthalmia detection method mainly includes intrusive breakup time of tear film detection, Schimer's test
(such as Schirmer I and II test), slit lamp examination and the German OCULUS Keratograph 5M released recently etc..Tradition
Breakup time of tear film (BUT) detection be corneal fluorescein sodium dyeing after under slit-lamp microscope observe cornea occur first
The time of dry spot, inspection result accuracy dependent on observer experience and coloring agent to the stability of tear film；Lacrimal secretion
Test 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 looks down or gently closes one's eyes, and removes test paper after five minutes, test paper scale is read after placing one minute, according to test value
Judge diagnostic result, this method can also be dripped in patient tests basic value under surface anesthesia state, and test paper stimulation itself is avoided to lead
The lacrimal secretion of cause influences the accuracy of test result, Schimer's test method be also the common method of current Clinical Ophthalmology it
One, it is at low cost, but the test process duration is long, and intrusive method 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, higher cost, and popularization is bad.
Existing dry eyes inspection method has the disadvantage that through analysis:
1, the method observed based on slit-lamp the cornea after fluorescent staining depends on the experience and dyeing of doctor
To the stability of tear film, inspection result subjectivity is strong, and unstable for agent, and patient is needed to instill coloring agent before checking, gives patient
Bring certain harm；
2, the Schimer's test method duration is long, and test paper invades and brings certain sense of discomfort, test result to patient
The tear that stimulation generates may be invaded by test paper is influenced, and accuracy is reduced；
3, Keratograph 5M equipment volume is larger, and portability is poor；
4, Keratograph 5M is integrated equipment, the inspection for the class patient that is not suitable for lying down；
5, the incompatible current eye examination equipment of Keratograph 5M device structure, occupied space resource are more.
