目的：研制一种儿童彩色视力表,并探讨其应用效果。 　　方法：视力表设计采用视角原理,用彩色图形视标,各行视标间增率以几何级数(1010),即1.2589增加。11个彩色图形,共8行,检查距离3m,视力记录为五分记录和小数记录。以标准对数视力表为对照,用新的儿童彩色视力表检查4~6岁儿童100眼。 　　结果：儿童彩色视力表和E字对数视力表检查,两组视力检查结果差异无统计学意义(t=1.2671,P>0.05),两组视力数据存在正相关(r=0.924,P<0.01)。合作率100%,对视标的识别率90%以上。 　　结论：儿童彩色视力表儿童容易接受,具有可靠性,适用于儿童视力的检查。

AlM: To introduce a new color pediatric visual acuity chart and its clinical application. METHODS:The color pediatric visual acuity chart was designed based on principle of visual angle. The optotype on the color chart had graphics. The progression rate of optotype size between 2 lines was 10 10 and 1. 2589. A regular geometric progression of optotype sizes and distribution was employed to arrange 8 lines with 11 optotype on the color chart. The testing distance was 3m. The visual acuity score could be recorded as logarithm of the minimum angle of resolution notation or decimal notation. The reliability of naked distant measurements with this new chart was tested in one eye of 100 children (4 ~ 6 years old) taking the Chinese national standard logarithm visual acuity chart standard. RESULTS: The color pediatric visual acuity chart and logarithmic chart controls, visual acuity test results that in the two groups had no significant difference (t=1. 2671, P> 0. 05 ). Two sets of vision data existed positive correlation (r= 0. 924, P<0. 01). Cooperation rate was 100%, the recognition rate was more than 90%. CONCLUSlON:Children are easier to accept used new color pediatric visual acuity chart to inspect vision. New chart is reliability and apply to children's vision screening.
