Imaging and computer processing of the ocular fundus picture

: Computer analysis of a picture in ophthalmology makes objective evaluation of the clinical finding possible. After analogue-digital transfer the pictures of the fundus on a black and white negative and coloured positive 24 x 36 mm were analyzed on a Pericolor 2000 E computer. We measured the area of the glaucoma excavation of the papilla of the optic nerve, calculated the C/D ratio, assessed changes in the picture of the fundus in exudative diabetic maculopathy on paired slides obtained after a one-year interval. We evaluated changes of fluorescein penetration during fluoroangiography in different diseases.
