Purpose To report the first case of a patient with essential thrombocythemia (ET) who presented with unilaterally extensive choroidal ischemia coinciding with central retinal artery occlusion (CRAO). Observations: A 64-year-old man presented with a classic sign of short posterior ciliary artery (SPCA) occlusion, Amalric triangular choroidal infarction, coinciding with CRAO in the left eye. He was later diagnosed as having ET due to a massive platelet count of 1,100,000 cells/mm3 and confirmed genetic testing. The magnetic resonance angiogram subsequently revealed severe occlusions of neuro-ophthalmic circulation. Interestingly, occult choriocapillaris occlusions were detected in the right eye despite being visually asymptomatic. Conclusion and importance Patients with ET can present with concurrent CRAO and SPCA occlusion. Identifying the causes of such events is crucial as these can precede systemic thrombocytosis or hemorrhagic complications.
