目的　运用火棉胶切片技术于光镜下观察研究豚鼠胚眼的发育进程。方法　运用胚胎于 19、2 4、2 8、35、40、43、45 d的豚鼠头颅火棉胶切片 ,于光镜下观察不同时期的豚鼠胚眼的发育变化。结果　胚胎于 19d视泡发育 ,晶状体板出现 ,2 4d视杯、晶状体凹形成 ,2 8d胚眼初步形成。结论　通过不同时期胚眼的观察 ,为进一步行胚眼的发育研究提供了客观依据 Objective To observe the development of the embryonic eye of guinea pigs by using the collidal technique. Methods The developmental changes of the embryonic eye of guinea pigs at different stages were observed under light microscope with embryonic day 24, 28, 35, 40, 43 and 45 days. Results The embryos developed as optic vesicles on day 19, the lens plate appeared, the optic disc was formed on 24 days, the lens was concave and formed on the embryo of 28 days. Conclusion The observation of the embryo eye at different stages provides an objective basis for the further development of the embryo eye
