摘要
目的:通过VEP验光结果与电脑验光结果的比较,评价VEP验光技术在眼外伤法医学鉴定中的应用价值。方法:通过对50例86眼不同程度的屈光不正依次行电脑验光和VEP验光,将两种方法所得的结果进行比较分析。结果:VEP验光与电脑验光结果比较无显著性差异。两者差值约有66.1%在0～0.25D之间;约有51.2%的电脑验光结果高于VEP验光结果。结论:在眼损伤的法医学鉴定中,VEP验光技术可以作为一种客观评价受检者屈光不正程度的验光手段。
AIM： Through comparison between visual evoked potentials （VEP） optometry and computer optometry, to estimate the application value of optometric technique of VEP in forensic appraisal about ocular trauma. METHODS： Computer optometry and VEP optometry were respectively performed on 86 eyes of 50 cases with ametropia of different degrees. The results of two methods were compared and analyzed. RESULTS： In the process of VEP optometry, 75 ametropic eyes were corrected through spherical lens, while 52 ametropic eyes were corrected by cylinder lens. The diopter difference in 84 eyes （66.1%） was less than 0.25D. The results of computer optometry were higher than VEP＇s in 65 eyes（51.2% ）. CONCLUSION ： The optometric technique of VEP can be used as an objective method to evaluate ametropic degree in forensic appraisal about ocular trauma.
