This study aims to establish the light and electron microscopic structure of the pecten oculi in the goose (Anser anser). For this purpose, 12 samples of pecten oculi extracted from 6 goose eyes were used. In the study, it was found that the goose pecten consists of 13-14 pleats. The maximum transversal length of the eye was approximately 10 mm, the corneal diameter was 5 mm, the basal length of the pecten was 7 mm, the apical length was 1.5 mm, and the height of the pecten was 5.55 mm (n=6). In pecten pleats, the mean diameters of two separate vessels, primary and secondary, were 48.94 and 23.36 μm respectively. The primary vessels located at the centre of the pecten pleats were surrounded by the secondary vessels. It was observed that the melanocytes in pleats gradually intensified from basal to apical regions. Pecten covered to the vitreo-pecteneal limiting membrane and, hyalocytes were found on this part. This study revealed that the goose pecten has a structure similar to the avian species in the waterfowl family.
