Abstract: Eye disorders can occur in 90% of cases of patients with hematological disease. Anemia is the most common blood disease that causes the most manifestations in the eye. Anemia causes retinal hypoxia, which causes infarction of the nerve lining and blood vessel disorders. Retinal hypoxia also causes dilation of blood vessels; increased transmural pressure which causes hypoproteinemia and microtrauma in the vessel wall, which causes retinal edema and retinal bleeding.
