Title

COMPARISON OF AN ITALIAN CHART WITH AN IRANIAN CHART IN VISUAL ACUITY MEASUREMENT

Pages

  43-47

Abstract

 Background: Taking VISUAL ACUITY is an important part of an eye routine examination. This study was conducted to compare VISUAL ACUITY measured using an Iranian digital TUMBLING E CHART with VISUAL ACUITY measured using an Italian digital TUMBLING E CHART as a familiar foreign chart.Materials and Methods: This study was carried out on 200 participants (400 eyes; healthy n=40, glaucoma n=40, retinal disorders n=40, post lasik n=40, corneal n=40) with mean age 44.28 years. VISUAL ACUITY of both eyes in half of the subjects (n=100, n=20 from each group) was first measured using the Italian DIGITAL CHART and then measured using Iranian DIGITAL CHART. VISUAL ACUITY of the rest of subjects (n=100, n=200 from each group) was first measured using the Iranian DIGITAL CHART and then measured using the Italian DIGITAL CHART. Measured visual acuities were recorded in logMAR notation.Results: Mean of the Iranian and Italian TUMBLING E CHART is 0.280 ± 0.012 and 0.277±0.012, respectively. Paired t-test used to evaluate the mean difference between two groups (p=0.721) indicated that there was no statistically significant difference between means of the two tests. Spearman correlation coefficient for the results of both tests was 0.942 (p<0.001), which was statistically significant and could be categorized as a strong positive correlation.Conclusion: The two digital TUMBLING E CHARTs acted similarly at different levels of acuity in different disorders. However, the Iranian chart requires a more accurate design for optotypes of the lower acuity lines in order to obtain more accurate measurement of visual acuities in healthy subjects.
