PRENATAL DEVELOPMENT OF THE RETINA IN ONE HUMPED CAMEL

The present study was conducted on 26 one-humped camel fetuses, two of each age. The specimens were collected from Cairo and Bani Adi slaughter houses. The eyes were subjected to routine histological examination. The data revealed that the optic vesicle in camel firstly appeared in 2 cm CVR length fetuses and its invagination to form the optic cup took place in 3.8 cm CVR length fetuses. The oblitration of the optic ventricle begins posteriorly and extends peripheraly. The first appearance of the photoreceptors was recorded at 77.5 cm and differentiated into inner and outer segment in 100 cm CVR length fetuses. Moreover all the layers of the retina of camel become differentiated in 100 cm CVR length fetuses.
