The effect of substance abuse on visuographic functions was investigated by comparing 4 groups from an Arabian Gulf population: 63 heroin abusers, 14 alcohol abusers, 43 polydrug abusers, and 48 control subjects. The visuographic function was evaluated using Benton's Revised Visual Retention Test. Analysis of covariance yielded an over-all group effect on both number correct and errors. Assessment of significance of differences between groups showed that the polydrug-abusing group and the heroin-abusing group scored significantly lower than the nonabusing group on number correct. All 3 substance-abusing groups scored significantly higher than the non-abusing group on errors, which seems a better predictor of cognitive impairment. Classification of subjects on the basis of their scores on the Benton test showed that a significant proportion of subjects in each substance-abusing group were classified as impaired. It is concluded that the present findings were consistent with prior reports for European and American subjects.
通过比较来自阿拉伯海湾地区人群的4组对象，研究了药物滥用对视觉成像功能的影响：63名海洛因滥用者、14名酒精滥用者、43名多种药物滥用者和48名对照对象。使用本顿修订视觉保持测验评估视觉成像功能。协方差分析得出了对正确数量和错误数量的总体组效应。组间差异的显著性评估表明，在正确数量方面，多种药物滥用组和海洛因滥用组的得分显著低于非滥用组。所有3个药物滥用组在错误数量方面的得分显著高于非滥用组，这似乎是认知障碍的一个更好预测指标。根据他们在本顿测验中的得分对对象进行分类表明，每个药物滥用组中相当一部分对象被归类为受损。得出的结论是，目前的研究结果与之前针对欧美对象的报告一致。
