Giant cell arteritis presenting as ischemic optic neuropathy
Giant cell arteritis (GCA) is a systemic vasculitis of medium and large-size vessels and can led to permanent visual loss in elderly patients. GCA is very rare among Asians. Published in BMC Ophthalmology, the authors eport a case of a patient presenting with acute bilateral anterior ischemic optic neuropathy, and the temporal artery biopsy proved the diagnose of GCA.

A 77-year-old man presented with sudden bilateral blindness for 5 days with a severe headache. Funduscopic examination revealed bilateral optic disc swollen with “chalky white” pallid appearance. The blood tests showed the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) elevated dramatically.

The color duplex ultrasonography (CDUS) of the superficial temporal artery revealed the inflammation of the vessel wall as a “halo sign”. The temporal artery biopsy was perfumed and the pathology revealed luminal occlusion with multinuclear giant cell infiltration.

The patient was treated with intravenous methylprednisolone for 3 days and oral prednisone weaning for 12 months. The visual acuity remained no light perception at one year follow-up.

Key takeaway:-
- The noninvasive CDUS might be a promising technique for diagnose GCA in highly suspected patients.
