Anatomical, Histological and Electron Microscopic Studies on Tunica Fibrosa Bulbi of Gerze Rooster and Chickens (Gallus domesticus)

This study was carried out to determine the anatomical and histological features of the tunica fibrosa layer of bulbus oculi in Gerze rooster and chicken. A total of 8 animals including 4 females and 4 males were used in the study. Macroanatomic, light and electron microscopic examinations were carried out on 16 bulbus oculi taken from orbita. With morphometric measurements it was determined that the bulbus oculi has a vertical elliptical appearance. Eyes that were totally removed in light microscopic examinations were fixed in 10% formol-alcohol solution. Following routine histological procedures, Crossman’s triple staining was performed to the sections taken 4 μm thickness to determine general structure. In the anterior part of the non-transparent sclera with blood vessels, bone plaques were present and sclera was supported all around by hyaline cartilage in continuation. The dome-shaped cornea was determined to be without vessel and transparent
