To report three various cases of retinal hemorrhages caused by Plasmodium vivax malaria. CASE SUMMARY: Two 55-year-old male patients and a 52-year-old male patient with cyclic high fever were admitted to the department of internal medicine. Three of the patients were diagnosed with malaria caused by P. vivax based on a peripheral blood smear. The patients were treated with hydroxychloroquine and premaquine but complained of decreased visual acuity. The patients were examined with funduscopy, fluorescein angiography, and optical coherence tomography. The first case showed 2 areas of retinal hemorrhages on the macular in the right eye and 1 area of retinal hemorrhage in the left eye. The second case showed many cotton-wool spots along with a number of small retinal hemorrhages and tortuous blood vessels in both eyes. The third case showed 1 area of retinal hemorrhage in the right eye and many cotton-wool spots in both eyes. CONCLUSIONS: P. vivax malaria rarely causes retinal hemorrhage. Manifestations of retinal hemorrhage and degree of visual acuity loss may vary among patients. P. vivax malaria should be considered when patients with unexplained high fever present with retinal hemorrhage, even without a history of overseas travel.
