<P>PROBLEM TO BE SOLVED: To enable not only the non-invasive measurement of changes with a passage of time in the lacrimal layers but also its quantitative analysis in an ophthalmologic apparatus which measures changes with the passage of time in the lacrimal layers formed on the surfaces of the corneas of the eyes to be examined. <P>SOLUTION: The ophthalmologic apparatus has a means for projecting the light onto the surfaces of the corneas in the prescribed pattern, a means for capturing the reflection images of the light projected from the surfaces of the corneas, a means for executing the operation repeatedly by the image pickup means at the given time interval and an image analysis means which uses one of a plurality of images captured by the image pickup means as the reference image and calculates the degree of correlation of other images with the reference image. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
