| Micro-papilla, Variant of the Norm | |
| This disc measures 1.82 mm² instead of 2.7 mm². Small discs often lack a physiologic excavation and are fully functional ( Jonas et al 1989). Glaucomatous damage is initially only seen as nerve fiber defects. An excavation is a sign of alarm. Visual field defects are later than morphological signs. Drusen, Pseudoedema and non-arteritic infarcts are frequent. (Measurement of the disc size from prints of standard fotos with a Zeiss fundus camera according to Littmann) | |
