PURPOSE: 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: One hundred and fifty-seven eyes of 157 ocular hypertensive subjects who met the selection criteria (intraocular pressure greater than 21 mmHg and normal standard visual fields) were studied. SWAP was performed with a modified Humphrey Field Analyzer. Total (TD) and pattern deviation (PD) probability maps were calculated for SWAP. The frequency of abnormalities 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.
