title: [Computerized image analysis of normal optic discs].
abstract: A self-designed computer system was used for image analysis of 172 normal optic discs, with Littmann's correction of photographic magnification. The mean disc area was found to be 2.40 +/- 0.50mm2, and the mean rim area 1.77 +/- 0.32mm2. The rim area was significantly correlated to disc area (r = 0.67, P = 0), but not to age, sex or refraction.
