Purpose: We report a case of papilledema without the typical symptoms of arteritic anterior ischemic optic neuropathy, ultimately diagnosed as a subtype of giant cell arteritis, which has not been reported previously in Korea.
Case summary: A 72-year-old man visited the hospital with decreased visual acuity in his left eye of 0.02 that had occurred 1 week prior. Optic disc swelling and relative afferent pupillary disorder were also evident in the left eye. Magnetic resonance imaging revealed no specific findings, leading to a diagnosis of anterior ischemic optic neuropathy. Afterwards, there was no improvement in visual acuity, and optic nerve atrophy occurred. Six months later, the patient complained of decreased visual acuity in the contralateral eye; the same clinical findings as in the left eye were confirmed. Temporal artery biopsy was performed, ultimately revealing a subtype of giant cell arteritis.
Conclusions: This case was finally diagnosed as a subtype of giant cell arteritis through temporal artery biopsy, despite the absence of typical clinical symptoms of this condition. Although giant cell arteritis is rare in Korea, it can cause permanent blindness. Therefore, the possibility of giant cell arteritis should always be considered with optic disc swelling in both eyes.
