Aim: To design and validate a MNREAD Asante Twi version reading chart, to aid in the assessment of near visual acuity of
Methods: Cross-sectional and experimental designs were employed in phases I and II respectively of this study. The chart was
developed using 20 transited pupils in class four in the Kumasi metropolis in phase I and validated in a clinical setting at the
Manhyia District Hospital, Kumasi, using students in phase II.
Results: A total of 100 participants (mean age; 22.19 ± 1.61 years) were involved in the second phase of this study. A Pearson
product-moment correlation coefficient was computed to assess the relationship between MNREAD Asante Twi charts
logMAR scores in both eyes. The MNREAD-Asante Twi acuity charts had very strong correlations (r = 0.94, p < 0.001) for
MNREAD set 1A (black on white background) scores and MNREAD set 2A (black on white background) for acuity scores.
Correlation between MNREAD set 1B (white on black background) scores and MNREAD set 2B (white on black background)
scores was r = 0.95, p < 0.001.
Conclusion: MNREAD Asante Twi reading chart will enhance the measurement of near visual function in native Ghanaians.
