- Abstract. If defined as diameter of image/diameter of object, the magnification M of the eye-camera system is kB, where k is a camera constant and B represents the vergence of the internal axis of the eye. The magnification may be assessed (1) from the length l of the eye, using the formula 1.336 k / ( l -0.0016); (2) from the glass refraction G, using the formula kD / (1- G/D ), in …

- Uncorrected length measurements on disc photos are deeply mistrusted despite their being strongly correlated to their corrected counterparts [1, 3, 5]. A simple factor, (1-0.017 G), in which G represents the glass refraction, was used by Bengtsson [3] to correct optic disc measurements on fundus photos.

- Purpose: To develop and evaluate a simple and rapid algorithm for optic disc measurements on digital fundus photographs, relying on the macula-disc centre distance as a reference when converting length expressed in pixels to metric distance. Methods: Measurements were performed on fundus photographs from 68 normal subjects, acquired using five different …
