The ocular fundus was examined in 40 goat eyes and 40 sheep eyes by studying ophthalmoscopic characteristics and retinograms. Similarities and differing characteristics were described. In common: tapetal colour; peripheral yellowish area surrounding the Winslow stars; unpigmented areas in the non-tapetal zone; a great amount of myelin in the optic disc; the Bergmeister's papilla and the holoangiotic retinal vascular pattern. Differences: big size of the Winslow stars in goats; myelinizated fibre over the non-tapetal zone in sheep; shape, position and myelin distribution of the optic disc; and the presence of a 'primary artery' in goats.
通过研究检眼镜特征和视网膜电图,对40只山羊眼和40只绵羊眼的眼底进行了检查。描述了它们的相似性和不同特征。共同点:反光膜颜色;围绕温斯洛星的周边淡黄色区域;非反光膜区的无色素区域;视盘中大量的髓磷脂;贝格迈斯特乳头和全血管性视网膜血管模式。不同点:山羊的温斯洛星尺寸较大;绵羊非反光膜区有髓鞘化纤维;视盘的形状、位置和髓磷脂分布;以及山羊存在“原发性动脉”。
