摘要
目的:观测兔眼正常玻璃体视网膜界面(VRI)基本的结构及相关生理。方法:新西兰大白兔20只,应用皮肤及角膜接触镜电极作为记录电极,测定其视网膜电图(ERG),记录其b波振幅(bA)值,并对其中4只眼的VRI结构进行组织病理学检查。结果:正常的VRI包括紧密相邻的玻璃体后皮质(PVC)和视网膜内界膜(ILL),并有其各自的特点;两种记录电极得到的正常兔眼双侧ERG的bA值无统计学差异(P>0.05)。结论:正常兔眼VRI的基本结构由PVC与ILL组成;ERG的bA值能较好地反映视网膜的生理功能。
AIM： To observe the normal structure and related physiological parameters of the vitreoretinal interface （VRI） in rabbit eyes. METHODS： The normal electroretinography （ERG） of 20 New Zealand rabbit eyes was measured, using two different kinds of recording electrodes. Also b wave amplitude values were recorded. Structures of VRI in 4 eyes of 2 rabbits were then checked with histological examination. RESULTS： Normal VRI consisted of posterior vitreous cortex （ PVC） and its adjacent internal limiting lamina （ILL） of the retina, each had its own characteristic in the structure; and the use of two recording electrodes made no significant difference between right and left eyes. CONCLUSION： Normal structure of VRI in rabbit eye is composed of PVC and ILL and the bA value of ERG is a good index for investigating the physiology of the retina.
