AIM
To design and validate a MNREAD Asante Twi version reading chart, to aid in the assessment of near visual acuity of natives Ghanaians.
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.
目的
设计并验证MNREAD阿散蒂语版阅读视力表，以辅助评估加纳当地人的近视力。
方法
本研究的第一阶段和第二阶段分别采用横断面设计和实验设计。第一阶段，该视力表是利用库马西市都会区四年级的20名转校学生开发的；第二阶段，在库马西曼希亚区医院的临床环境中，以学生为对象对该视力表进行验证。
结果
本研究的第二阶段共纳入了100名参与者（平均年龄；22.19±1.61岁）。计算了皮尔逊积差相关系数，以评估MNREAD阿散蒂语版视力表两眼logMAR分数之间的关系。MNREAD阿散蒂语视力表中，MNREAD第1A组（白底黑字）分数与MNREAD第2A组（白底黑字）视力分数具有很强的相关性（r = 0.94，p < 0.001）。MNREAD第1B组（黑底白字）分数与MNREAD第2B组（黑底白字）分数之间的相关性为r = 0.95，p < 0.001。
结论
MNREAD阿散蒂语版阅读视力表将提高对加纳当地人近视力功能的测量。
