| Popis: | The present study was carried out to investigate the morphological and histomorphometric characters of choroid in donkeys, buffalos, camels and dogs. The findings of the study revealed that, macroscopically, the choroid was consisted of two areas in all studied animals, except in camel which consists of one area. Histologically, the choroid consists of five layers. Interestingly, the anterior borders of all investigated animals were free of pigments except in camel. Morphometric analysis revealed significant species differences in the mean total thickness of the choroid and its different layers. In addition, significant differences were also found between the ratios of the means of different layers to the total thickness of the choroid. In conclusion, these variations might be related to the different lifestyles and visual behavior of the investigated animals. |
