Comprehensive ocular surface analyzer based on expert system

Abstract

The invention relates to a comprehensive ocular surface analyzer based on an expert system. The comprehensive ocular surface analyzer comprises a comprehensive ocular surface analyzer hardware module, an image processing module and an expert system module, wherein the comprehensive ocular surface analyzer hardware module comprises a controller, a structured illumination module and an imaging module; the image processing module comprises a tear meniscus height measuring module, a red eye detection module, a tear film stability detection module, a meibomian gland morphology detection module and a corneal topography analysis module; and the expert system takes information acquired though image processing as the input, performs objective and correct judgment on common diseases of the human ocular surface and provides therapeutic measures.

Description

technical field [0001] The invention relates to the diagnosis of human ocular surface diseases, in particular to an analysis and diagnosis instrument for human ocular surface diseases. Background technique [0002] Human ocular surface diseases refer to diseases that damage the normal structure and function of the corneal and conjunctival ocular surface. Common ocular surface diseases include keratoconus, dry eye, meibomian gland dysfunction, etc. Keratoconus is an eye disease characterized by corneal dilatation, central thinning, and protruding forward in a conical shape. It often causes highly irregular myopic astigmatism, and in the advanced stage, acute corneal edema, scarring, and significant loss of vision will occur. Inspection methods include corneal topography, Placido disc, keratometer, etc. Dry eye syndrome refers to the general term for various diseases caused by abnormal tear quality or quantity or abnormal dynamics caused by any reason, resulting in decrease...

AI Technical Summary

Problems solved by technology

There are few instruments for comprehensive diagnosis of common diseases of the human ocular surface, and the test results also require subjective comprehensive evaluation and diagnosis by expert physicians. The diagnostic results of different physicians may be different, and it will consume a lot of time and manpower.

The ocular surface comprehensive analyzer manufactured by OCULUS in Germany can detect corneal topography, red eyes, tear river height, meibomian glands, tear film breakup time and other items, but it is still difficult to meet the needs of clinical diagnosis, such as meibomian glands Extraction and calculation of missing rate, detection of tear film thickness, automatic extraction of tear river height, etc.

At the same time, the system does not comprehensively analyze and evaluate the data of the test results of each item, and provides the diagnosis and prevention measures for ocular surface diseases.
