| Description | Visual acuity determination is important task in ophthalmology and optometry practice. Examination method sVEP enables quickly determine objective values of patient’s visual acuity. We divided our sample into two parts. In first group is measured visual acuity with sVEP and Snellen method only on one patient. In the second group is measured visual acuity twice with sVEP and next twice with Snellen method in Landolt rings and logMAR modification. Until now we have measurements from 13 non-pathological patients. Results form first group of data shows significant correlations between both methods (sVEP and Snellen). But their average values differ at statistical significant level (p < 0.01). In the second group we showed significant correlations between repeated sVEP measurements and between first sVEP measurement and first Snellen measurement too (r = 0.97 and r = 0.80). T-test showed no statistical significant differences between repeated sVEP measurements and between first sVEP measurement and first Snellen measurement (p = 0,13 a p = 0,06). |
