Abstract

The present work was designed to reveal the fine structure of the pigment epithelium of the retina in four different reptiles: the homed viper Cerastes cerastes (diurnal and nocturnal), the European Chameleo chameleon (diurnal),the gold skink Eumeces schenrdii (diurnal) and the Egyptian gecko Traentola annularis (nocturnal) . The pigment epithelium of each type reptiles possessed certain unique features in their morphology and ultrastructure to accommodate with their day and night activity. The most striking feature was the presence of myoid bodies in the pigment epithelium of the diurnal reptiles. These bodies trigger the photomechanical movement of the myoid region in cones of their retinae.
