[A study on method of measurement and analysis of anterior chamber configuration by computerized image processing].

A new computerized method of measurement and analysis of the anterior chamber configuration in the human eye is described. The image or photograph of the anterior chamber taken with a slitlamp microscope is inputted into a computer with digitized camera or digitizer. After cornea, iris and lens surfaces are digitized, methematical corrections are made for the distortion from the slitlamp microscope and the refractive effect of cornea and aqueous humor to convert an optic distorted image into a true image. From the corrected image of anterior chamber, the data and parameter of anterior chamber configuration are measured and calculated. The reproducibility and accuracy of the method were 1.78% approximately 4.66% and 0.05 mm respectively and found to be adequate for clinical study of human eye under physiologic or disease state.
