title: Glaucomatous damage patterns by short-wavelength automated perimetry (SWAP) in glaucoma suspects.
abstract: OBJECTIVE
  To determine the glaucomatous visual field damage patterns by short-wavelength automated perimetry (SWAP) in glaucoma suspects, and to compare the frequency of diffuse visual field losses and localized defects.
  
  
  METHODS
  157 eyes of 157 ocular hypertensive subjects who met the selection criteria (intraocular pressure greater than 21 mm Hg and normal standard visual fields) were studied. SWAP was done with a modified Humphrey Field Analyzer. Total (TD) and Pattern Deviation (PD) probability maps were calculated for SWAP. The frequency of abnormlities in the TD and PD were determined, analyzing the visual field loss components.
  
  
  RESULTS
  The involvement of the test points was more frequent on the TD plots than on the PD plots for all levels of defects (p< 0.001). The glaucomatous defects also showed certain topographical distribution.
  
  
  CONCLUSIONS
  A diffuse sensitivity component of visual field loss was found at all SWAP defect depths in glaucoma suspects.
