Tissue samples were fixed in 10%neutral-buffered formalin solution for 24 hours. After fixation samples weretreated routine procedure and blocked. Serial sections were taken from theblocked. Those sections were examined under the microscope after stained with byCrossman’s triple stain. The pecten oculi projects from the optic nerve headinto the vitreous chamber. Differently, it was seen that retina in pigeons wasnot completely separate from pecten base and ganglion cell layer were continuedfor a bit more. There were vessels with wide diameters on the basal part wherepecten was located. This vessel was found to have originated from choroid. Itwas also seen that vessel diameters got smaller as it went to the apical fromthe basal. So, the vessels were classified as primer, secondary, and tertiaryvessel. Diameters of 20 randomly chosen vessels from each sections weremeasured and an average diameter value was found. There was also a littleamount of melanocyte in the basal part of the pecten. These melanocytes werebased on the laminated vasculosa of the choroid. Pecten oculi were coveredpecteneal membrane. Besides pecteneal hyalocytes were found in the pecteneallimiting membrane. According to the findings of the study, it was first provento have originated from choroid that pigeon’s veins and melanocytes at thepecten oculi.
