PURPOSE: 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 of 83 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 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: The authors documented the existence of predominantly diffuse visual field defects for all depth levels at early glaucoma stages. LA: Spanish
