Method for measuring ocular surface temperature and apparatus thereof

Abstract

The present invention provides a method for measuring ocular surface temperature and an apparatus thereof. The method herein at least comprises the following steps: providing an infrared thermography sensor, wherein the infrared thermography sensor detects the heat radiation emitted by a blackbody, and a calculation unit of a working station calculates the heat radiation to generate a correction reference temperature so as to correct the infrared thermography sensor with the correction reference temperature; using the infrared thermography sensor to detect variations of the ocular surface temperature of a detection object within a time unit so as to generate a measure result; and providing a storing unit based on the technical solution of the method aforementioned so as to support the implementation of the method and address the problems of poor accuracy of temperature measurement by using infrared rays.

Description

technical field [0001] The present invention relates to a method and device for measuring ocular surface temperature, in particular to a method and device for measuring ocular surface temperature using blackbody thermal radiation as a reference temperature for calibration. Background technique [0002] In the prior art, the means of tear film breakup used to measure dry eye syndrome are roughly divided into contact and non-contact methods, wherein the contact measurement means include Schirmer and Tear Break Up Time (Tear Break Up). Time, TBUT). Taking graphite as an example, the measurement method is to place a long filter paper on the lower eyelid after the eyes are anesthetized, so that the filter paper can absorb the tears on the surface of the eyeball through capillary phenomenon. The water content of the tear film was evaluated by observing the diffusion length of the tear fluid absorbed on the filter paper in the filter paper. The tear film breakup time refers to th...
