Volunteers over 20 years of age without apparent ophthalmic abnormalities were examined with the SITA-S central 30-2 program followed by the Dynamic 32 program. Eye with corrected visual acuity ≥0.8, refraction ≥ −6.0 diopters, and fields with satisfactory levels of reliability in SITA-S and Dynamic were selected.Results: Sixty-seven eyes from 67 normal individuals of mean age 51.3 ± 16.3 (range 22–76) years satisfied the selection criteria and were analyzed. Mean retinal sensitivity was significantly (P < 0.0001) higher with SITA-S (29.0 ± 2.4 dB) than with Dynamic (26.8 ± 2.1 dB). Changes in retinal sensitivity with increasing age were significantly (P = 0.0003) greater with Dynamic (−0.09 ± 0.04 dB/year; 95% confidence interval [CI] −0.10 to −0.08 dB/year) than with SITA-S (−0.07 ± 0.04 dB/year, 95% CI −0.08 to −0.06 dB/year). When classifying the visual field into three areas (central, mid-peripheral, and peripheral), retinal sensitivities with SITA-S were significantly higher in all areas than with Dynamic (P < 0.0001 for all three areas).Conclusion: Differences in Dynamic and SITA-S strategies may contribute to the differences in retinal sensitivities observed in normal individuals.Keywords: time-saving strategy, frequency-of-seeing curve, dynamic, Swedish Interactive Threshold Algorithm Standard, Octopus perimeter, Humphrey field analyzerSuzumura HYoshikawa KMizoue SHyodo RKimura TDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 1873-1878 (2012)
