摘要: 目的 研究视力表投影仪视力(以下简称“投影仪视力”)与对比度视力测量值的相关性,探讨对比度视力在眼损伤后法医临床学视觉功能障碍鉴定中的应用价值。 方法 征集中青年志愿受检者79人共129眼作为实验组,分别检查其投影仪视力与对比度视力。对比度视力中,视标对比度分别为100%、25%、10%。统计分析两组实验数据的相关性。 结果 投影仪视力与100%对比度视力具有一致性;随视标对比度的下降,视力值的大小下降;相同视标对比度下,投影仪视力与对比度视力的均值呈线性相关。 结论 投影仪视力和对比度视力密切相关,对比度视力可以在法医临床学司法鉴定实践中推广应用。

Abstract: Objective To study the correlativity between the projected visual chart vision (“projector vision” in this paper) and the measured values of contrast vision, and to explore the application of contrast vision in identifying visual impairment after eye injury in the clinical forensic medicine. Methods One hundred and twenty nine eyes of seventy-nine young volunteers were collected for examination both of projector vision and contrast vision. In the examination of contrast vision, the contrast of optotypes were set to 100%, 25% and 10%, respectively. The correlativity of both collected experimental data were statistically analyzed. Results Projector vision was consistent with 100% contrast vision. There was a close and positive correlation between the contrast of optotypes and measured vision values. Under the same contrast of optotypes, projector vision presented a linear correlation with the average value of contrast vision. Conclusion There is a close correlation between projector vision and contrast vision. The contrast vision can be applied to judicial identification in the clinical forensic medicine.
