We recorded ERG b- and c-waves from rabbit eyes with experimental retinal detachment and investigated the relationship between amplitude of the ERG and extent of the detachment. Three different extents of detachment (20, 60, 100% of the fundus) were made in three different groups of rabbits. In all 3 groups, the amplitude of both b- and c-waves remarkably decreased 1 hour after detachment and recovered at 6 hours to values corresponding to the extent of detachment. At 12 hours, the b-wave amplitude remained at almost the same values at 6 hours, whereas the c-wave amplitude showed further reduction. It was suggested that functional disorder in undetached retina occurred earlier in the retinal pigment epithelium than in the sensory retina of the eyes in the acute stage of the retinal detachment.
我们记录了实验性视网膜脱离的兔眼的视网膜电图b波和c波，并研究了视网膜电图振幅与脱离程度之间的关系。在三组不同的兔子中造成了三种不同程度的脱离（眼底的20%、60%、100%）。在所有3组中，脱离后1小时b波和c波的振幅均显著降低，并在6小时恢复到与脱离程度相对应的值。在12小时时，b波振幅在6小时时几乎保持在相同的值，而c波振幅进一步降低。提示在视网膜脱离急性期，未脱离视网膜的功能障碍在视网膜色素上皮比在眼的感觉视网膜更早出现。
