Polyarteritis nodosa (PAN) is the necrotic vasculitis affecting middle and small-sized arteries throughout the body including ocular tissue. We report an atypical PAN case of unilateral central retinal artery occlusion in which the ocular involvement occurred before systemic symptoms. CASE SUMMARY: A 58-year-old male visited the ophthalmology department due to abruptly decreased visual acuity. Best corrected visual acuity (BCVA) was 0.05 (in the right eye) and 1.0 (in the left eye) basedon the Snellen chart. He complained of acute decreased vision occurring ten days prior and intermittent migraine on the right side with no underlying diseases, such as hypertension or diabetes mellitus. Relative afferent pupillary defect was observed in the right eye. Generalized edema was found around the optic disc and fovea on fundus examination and optical coherence tomography. The patient was diagnosed with central retinal artery occlusion (CRAO) based on a fluorescein angiography. Subsequently, PAN was diagnosed based on clinical features, laboratory test results and imaging studies. The treatment was started with an immunosuppressive agent. One month later, the BCVA was 0.05 based on the Snellen chart. CONCLUSIONS: In PAN patients, decreased vision can occur as a first symptom due to CRAO. If the patient visits the ophthalmology clinic, history taking and laboratory tests for PAN can aid in early diagnosis and treatment, as well as preventing additional complications of PAN.
