Purpose: To prospectively compare frequencies of disturbed points detected with SITA standard (SS) and Full Threshold (FT) perimetry in a group of normals, ocular hypertensives, glaucoma suspects and glaucoma patients. Methods: Distributions of disturbed points in total and pattern deviation maps, obtained from SS and FT visual fields (Humphrey Field Analyzer, program 24–2)in 130 eyes of 130 subjects through repeated measurements, were analysed and compared between strategies. Results: In normal subjects, distributions of abnormal points were comparable at every probability of normality (pN) level between strategies, in both total and pattern deviation maps. In ocular hypertensives, glaucoma suspects and glaucoma patients, SS detected a significantly higher number of abnormal points than FT, and more frequently in pattern than total deviation maps. Regarding the different pN groups, differences were most frequently seen at the 0.5 % level in glaucoma patients. Conclusions: Results suggest SS shows a higher sensitivity than FT to detect glaucomatous damage, not only in glaucoma patients, but also in glaucoma suspects and ocular hypertensives, without any accompanying decrease in specificity, along time.
