title: [Glaucomatous damage pattern in swap in the early stages of glaucoma].
abstract: OBJECTIVE
  To determine with Short-Wavelength Automated Perimetry (SWAP) the patterns of early glaucomatous damage and to compare frequency of diffuse defects to localized defects.
  
  
  METHODS
  One hundred and sixty eyes from 83 ocular hypertensive subjects who met the selection criteria (intraocular pressure greater than 21 mm Hg and normal standard visual fields) were studied. SWAP was performed with a modified Humphrey Field Analyser. Total (TD) and pattern deviation (PD) probability maps were calculated to evaluate the pattern of visual field loss.
  
  
  RESULTS
  The frequency of defects was higher in TD than in PD for all levels of defects (p<0.001). There was also a relative topographical distribution of glaucomatous defects.
  
  
  CONCLUSIONS
  We documented the existence of predominantly diffuse visual field defects for all depth levels at early glaucoma stages.
