对26例正常人的上、下、颞部和鼻部黄斑分别进行半圆(半圆盘)刺激诱发视网膜电信号(ERG)，比较对侧黄斑区ERG的波幅和潜伏期。上黄斑区的a波、b波和振荡电位(OPs)的波幅明显大于下黄斑区(P<0.05)。A波和b波的振幅在颞区和鼻区之间无显著差异，但OPs表现出极大的不对称性，且颞侧视网膜的振幅显著大于鼻侧视网膜(P<0.001)。A波、b波和OPS的潜伏期在上下视网膜、颞侧视网膜和鼻侧视网膜之间无显著差异。这些发现有助于对一名视网膜缺陷患者的ERG进行分析。
Electroretinograms (ERGs) were elicited by hemicircular (half-disc) stimuli to the upper, lower, temporal and nasal maculas of 26 normal subjects, and the amplitudes and implicit times of the ERGs from opposing macular regions were compared. The amplitudes of a-wave, b-wave and oscillatory potentials (OPs) were significantly larger in the upper macular region than in the lower macular region (P less than 0.05). The amplitudes of a- and b-waves did not differ significantly between temporal and nasal macular regions, but OPs showed enormous asymmetry, with significantly larger amplitudes in the temporal retina than in the nasal retina (P less than 0.001). The implicit times of a-waves, b-waves and OPs did not differ significantly between upper and lower retina, or between temporal and nasal retina. These findings aided analysis of the ERG of a patient with a retinal defect.
