Abstract- A two- phase model consisting of a core region of suspension of all the erythrocytes in plasma assumed to be a particle-fluid mixture and a layer of plasma has been proposed to represent blood flow in small diameter tubes. In this work we have formulated the Ocular blood flow in arterioles. As we know that the arterioles are remote from heart. The viscosity increases in the arterioles due to formation of Roulex along axis of red blood cells. V. upadhayay has assumed that the blood flow as two phased. He has also applied the Herschel Bulkley Non Newtonian model in Bio fluid mechanics. In this paper we have collected a clinical data in case of Ocular disease Cataracts. The graphical presentation for a particular parametric value is very close to clinical observation. The overall presentation is in Tensorial form. The roll of Hematocrit is explicit in determination of blood pressure in case of Ocular disease Cataracts.
