目的:观察图形视力表与E字视力表在学龄前儿童视力检查中的临床应用,探讨提高学龄前儿童视力检查准确性的检查方法。方法:采用图形视力表与E字视力表检查3～6岁学龄前儿童103例的视力水平,并进行分组统计分析。结果:两种检查方法均能有效地检查儿童视力水平,两者检查结果呈正相关性(P<0.01);图形视力表检查所得视力均值比E字视力表检查所得视力均值低约1行视标水平;3～4岁组儿童图形视力表的检查满意率显著高于E字视力表(P<0.05)。结论:图形视力表与E字视力表均能有效检测学龄前儿童的视力水平,前者检查所得视力均值比后者均值低,注意避免过高估计儿童视力水平;对4周岁以下的儿童应首选图形视力表检查,以提高儿童检查配合满意率。
OBJECTIVE: To observe the clinical application of pictogram and E-chart in visual acuity test in preschool children and to explore the method to improve the visual acuity test in preschool children. Methods: The visual acuity of 103 preschoolers aged 3 ~ 6 years old was examined by the chart visual acuity chart and the E - word visual acuity chart, and the statistical analysis was made by grouping. Results: Both methods can effectively check the level of visual acuity in children. The results of the two tests showed a positive correlation (P <0.01). The visual acuity of the chart visual acuity chart was about 1 line lower than that of the E-chart visual acuity test (P <0.05). Satisfaction rate of visual acuity chart in children aged 3 ~ 4 was significantly higher than that of E chart (P <0.05). Conclusion: Both visual acuity chart and visual acuity chart can effectively detect preschool children ’s visual acuity. The mean visual acuity of the former is lower than that of the latter, so as to avoid overestimating the visual acuity of children. For children under 4 years of age, the preferred pictorial Eye chart inspection to improve children’s satisfaction with the inspection rate.
