Two animal groups were subjected to electroretinographic studies under identical circumstances with the exception of the coating agent on the surface of the corneal electrode, which consisted in one group of an ophthalmic artificial tear solution containing 1.6% hydroxyethylcellulose, and in the other group, an ophthalmic artificial tear solution containing 0.2% hydroxyethylcellose. A similar comparative recording was performed on five human subjects. Electrophysiological responses recorded with 0.2% ophthalmic artificial tear solution increased up to 81%, as compared to the values obtained with the 1.6% solution. The difference in electrical conductivity of these two solutions, which is also time dependent, correlated with differences in electroretinographic amplitudes. I cannot explain these observations at the present time.
将两组动物在相同情况下进行视网膜电图研究，唯一的区别在于角膜电极表面的涂层剂，一组使用含有1.6%羟乙基纤维素的眼科人工泪液，另一组使用含有0.2%羟乙基纤维素的眼科人工泪液。对五名人类受试者进行了类似的对比记录。与使用1.6%溶液获得的值相比，使用0.2%眼科人工泪液记录的电生理反应增加了81%。这两种溶液的电导率差异（也是时间依赖性的）与视网膜电图振幅差异相关。目前我无法解释这些观察结果。
