视网膜色素上皮细胞的眼底荧光血管造影观察

MORPHOLOGY FO LIVE RETINAL PIGMENT EPITHELIAL CELIS

对３１只有色家兔６２眼行眼底荧光血管造影，将其负片直接在光学显微镜下放大观察。将观察结果与扫描电镜及荧光显微组织标本下的同类家兔视网膜色素上皮（ＲＰＥ）细胞形态进行比较研究。５８眼荧光造影中可观察到中央低荧光，呈近六角形的ＲＰＥ细胞像。其形态与扫描电镜及荧光显微镜下观察到的ＲＰＥ细胞排列、形态均一致。白色家兔眼底则未能观察到上述结果。

Shin Yoneya Fluorescein angiography(FA)was performed in 31 pigmented rebbits,The angiogramswere evaluated as prints and as negative film under a light microscope;The patterns of retinalpigment epithelitql(RPE)cclls were studied by scaning clectron microscopy and fluoresceinlight one,compared with other rahbits helonging to the same species. In 58 eyes,we observedthe hexagonal pattern of RPE cell.It showed central hypofluorescent area surrounded by hy-perfluorescent rim,which was easily seen away from the medullary rays hy three or more discdiameters and became larger in the periphery than that in the posterior pole. There were nofinding in four ligl1tly pigmentcd eyes.
