title: [Morphology of the optic papilla in glaucoma. I. Primary open-angle glaucoma].
abstract: BACKGROUND
  Previous studies have shown that the chronic open-angle glaucomas form a heterogeneous spectrum of diseases which have in common an open anterior chamber angle and glaucomatous optic nerve damage. Purpose of this study was to evaluate whether the appearance of the optic disc differs among the various types of primary open-angle glaucoma.
  
  
  METHODS
  Color stereo optic disc photographs of 683 patients with primary open-angle glaucoma (POAG), and 481 normal eyes were morphometrically evaluated.
  
  
  RESULTS
  Morphologic characteristics of the glaucoma types were as follows: Highly myopic POAG: secondary macrodiscs with abnormal shape; shallow, flat, concentric disc cupping; low frequency of disc hemorrhages; large parapapillary atrophy or myopic crescent; medium to low intraocular pressure. Juvenile-onset POAG: Optic disc of normal size and shape; deep and steep disc cupping; low frequency of broad rim notches or large disc hemorrhages; small parapapillary atrophy; high minimal and maximal intraocular pressure measurements. Age-related atrophic POAG: Optic disc of normal size and shape; shallow, flat and concentric disc cupping; medium to low frequency of disc hemorrhages; large parapapillary atrophy; medium to low intraocular pressure. Eyes with normal-pressure glaucoma: Optic disc of normal size and shape; deep and steep cupping; relatively small parapapillary atrophy; high frequency of disc hemorrhages and rim notches.
  
  
  CONCLUSIONS
  These characteristics in the appearance of the optic disc may be helpful for clinical diagnosis and therapy and may give pathogenetic hints.
