The Survey of Effects of Unilateral Ligation of Common Carotid Artery on Ultra Structural of Photoreceptor Cells of Retina in Dog
A. Esfandiari, A. Yousof and A. Aliabadi

Abstract:
The aim of this study was to determine what histological changes occur in the photoreceptor layer of male dogs after unilateral ligation of common carotid artery of different times. Twenty adult male dogs were randomly divided into 4 groups: control group, experimental group I, experimental group II and experimental group III. All of experimental groups (I, II, III) were done ligation of common carotid artery for 12 h , 24 h and 1 week, respectively. The retinas of eye were removed and studied by transmission electron microscopy. The experimental group 1 showed the least photoreceptor damage, such as some loss of mitochondrial cristae in the inner segment, but other layers appeared normal. The experimental II animals showed sublethal injury in the inner segment such as a few vacuolization and loss of mitochondrial cristae, but normal appearance in other layers. In the experimental III animals, disorganization and distention in the outer segments, cell swelling in the inner segment and pyknosis and karyolysis in the outer nuclear layer were present. Present findings have confirmed that photoreceptor cells damage occurs in dog retina after ligation of common carotid artery for 1 week.
