Morphological investigation of the pecten oculi in quail (Coturnix coturnix japonica)

In this study pecten oculi was investigated morphologically in quail (Coturnix coturnix japonica). It was detected that the pecten oculi was attached to the retina and consisted of 19 folds on average. It was observed that quail pecten was in the pleated group and had a shell like rhomboid shape. The width of the folds was 259 mu m on average. The width of the each fold was constant on every region of the fold. In light microscopic investigation, pecten was consisted of large number of capillaries and pigment cells (melanocytes) and the basal edge of pecten lined from the ventral part of the optic disc through the retina ventrally and projected into the vitreous body.
