Morphologcal study of the pecten oculi from ostrich (Struthio camelus)
Objective To investigate the anatomy and histology of 10 ostrichs’ pecten in order to provide morphological base for research of ostrich pecten oculi. Methods The morphology of the pecten oculi was observed with a microscope in the 10-month-old healthy Africa black-neck ostrich (Struthio camelus) by hematoxylin-eosin staining, Gordon-Sweet staining, and Van Gieson staining. Results Gross-anatomically, the pecten oculi was attached to the optic disc, and had an irregular cone shape and projected into the vitreous body. In the steromicroscope investigation, the pecten oculi was composed of 1 primary lamella, 18-22 secondary lamellae and a few tertiary lamellae. The primary lamella was vertically located in the central part of the pecten, the secondary lamellae were peripherally originated from the primary lamella with the tertiary lamellae which arose from the distal part of some secondary lamella. The pecten consisted of loose connective tissue and was rich in collagen fibers, blood vessel and pigment. Conclusion Pecten oculi in the ostrich is an ideal model for the research of the function of retinal blood vessel form mammal and human.
