This study examines the validity and reliability of a reading speed test as a measure of potential central vision. Reading speed was calculated in words per minute (wpm) from the time taken to read 30 words of 1.20 logMAR size text. Scores were obtained from subjects with cataract (n = 48), macular disease(n = 35), peripheral vision loss(n = 14) and normal eyes (n = 10). Subjects with macular disease (27.0 +/- 13.2 wpm) read much slower than subjects with cataract (91.9 +/- 13.6 wpm). Little difference was found between subjects with cataract, peripheral vision loss (91.5 +/- 14.7 wpm)and normal eyes (103.8 +/- 15.5 wpm). Repeat testing gave values within +/- 16% of reading speed. These results suggest that a reading speed test using large text could be useful as a potential central vision test in cataract patients.
本研究检验了一种阅读速度测试作为潜在中心视力测量方法的有效性和可靠性。阅读速度通过阅读1.20 logMAR大小文本的30个单词所用时间计算得出，单位为每分钟单词数（wpm）。从患有白内障的受试者（n = 48）、黄斑疾病患者（n = 35）、周边视力丧失患者（n = 14）和正常眼睛的受试者（n = 10）中获取分数。患有黄斑疾病的受试者（27.0 +/- 13.2 wpm）阅读速度比患有白内障的受试者（91.9 +/- 13.6 wpm）慢得多。在患有白内障的受试者、周边视力丧失患者（91.5 +/- 14.7 wpm）和正常眼睛的受试者（103.8 +/- 15.5 wpm）之间未发现显著差异。重复测试得到的阅读速度值在±16%以内。这些结果表明，使用大字体文本的阅读速度测试可能作为白内障患者潜在中心视力测试是有用的。
