Case Report:
Essential thrombocytosis is a disorder of the hematopoietic stem cell that causes proliferation of platelets. We report two cases: a 72-year-old woman with ischemic retina and tortuous and white veins in the superior retina and diffuse hemorrhages in the inferior retina with blot hemorrhages scattered throughout the equatorial region in the left eye; and a 62-year-old man with a central retinal vein occlusion in the left eye as signs of essential thrombocythemia.
Discussion:
These cases are examples of potential complications of essential thrombocytosis. Vulnerable patients should be monitored for retinal vascular occlusions, especially when platelet counts do not exceed 106/mm3.
