目的 研究正常人中心30°蓝黄视野检测的表现特征及其相关影响因素.方法 采用横断面研究设计方法.应用Humphery750 Ⅱ-I计算机自动视野计的蓝黄视野30-2程序和Fastpac策略,对58例(116只眼)正常人进行30°蓝黄视野检侧,就其平均视网膜光敏感度、平均视野缺损值及模型标准变异均值3个视野指数及其影响因素进行分析.采用SPSS 13.0统计学软件进行数据处理.各年龄组间蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值比较,采用多因素随机区组设计方差分析;应用Pearson相关分析法分析年龄和视野指数的相关性,以简单线性回归模型定量描述两者之间的回归分析结果;应用χ~2检验,分析各年龄组人数和性别构成比的差异.检验水准α=0.05.结果 正常人中心30°蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值分别为(21.23±2.96)、(-3.94±2.20)及(3.13±0.72)dB.正常人不同眼别之间蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值的差异均无统计学意义(F=0.488,0.833,0.677;P=0.487,0.482,0.414);正常人不同性别之间蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值的差异亦均无统计学意义(F=0.149,0.547,1.948;P=0.702,0.463,0.169);正常人不同年龄组之间蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值的差异有统计学意义(F=48.160,54.250,9.329;P=0.000,0.000,0.032);正常人各年龄组不同象限之间蓝黄视野检测的平均视网膜光敏感度差异有统计学意义(象限因素F=81.544,P=0.000),年龄每增加10岁,平均视网膜光敏感度下降2.5 dB,平均视野缺损值增加-0.932 dB;不同偏心度范围间的平均视网膜光敏感度差异有统计学意义(偏心度因素F=48.257,P=0.000).结论 正常人中心30°蓝黄视野检测的平均视网膜光敏感度、平均视野缺损值及模型标准变异均值不受性别、眼别的影响,各象限的平均视网膜光敏感度具有不对称性.随着偏心度的增大,平均视网膜光敏感度下降越明显并随年龄增长呈直线下降趋势.

Objective To investigate the normal values and related factors of blue on yellow perimetry (BYP) in the central 30 degree.Methods A cross sectional study design was performed on this study.BYP was performed in a Humphery750 Ⅱ-I perimetry with 30-2 procedure and Fastpac strategy.The study samples consisted of 116 eyes of 58 normal subjects.The visual field indices were calculated and their related factors were analyzed.SPSS 13.0 software package was used for experiment data analysis.Comparison of three blue-on-yellow visual indices, including mean sensitivity (MS), mean defect (MD) and pattern standard deviation ( PSD), were investigated by multi-way ANOVA with randomized block design method among four age groups.Relationship between age and visual field index was described and interpreted by calculating Pearson preduct-moment correlation coefficient and linear regression.Chi-square test was applied to determine the distribution of population and gender among four age groups.Significance level was set to α=0.05.Results Values of the three different visual indices, MS, MD and pattern PSD,in central 30 degree of BYP were (21.23±2.96)dB, (-3.94±2.20) dB and (3.13±0.72) dB,respectively.The differences of MS, MD and PSD values between right eye and left eye were not statistically significant (F=0.488, 0.833, and 0.677, with P=0.487, 0.482 and 0.414, respectively).No differences in these three indices could be detected between male and female (F=0.149,0.547 and 1.948,with P= 0.702,0.463 and 0.169, respectively).Significant difference in three visual field indices was identified among four different age groups ( F=48.160,54.250 and 9.329, with P=0.000, 0.000 and 0.032, respectively ).The light average sensitivity in four quadrants showed statistically significant difference in all age groups (F value for quadrant factor was 81.544, P=0.000).The MS value decreased 2.5 dB and the MD value increased-0.932 dB with the 10-year-old increasing.The average sensitivity in different eccentric ranges had a significant statistical difference(F value for eccentricity factor was 48.257,P=0.000).Conclusions The gender and the laterality do not affect the MS, MD and PSD in the BYP of normal subjects.The light average sensitivity is asymmetry in the four different quadrant, decreases in a linear decline with age and declines with the eccentricity.
