Risk factors and treatment window in arteritic anterior ischaemic optic neuropathy: a case study

A 76-year-old NZ European man presented with sudden onset visual loss in his left eye after experiencing intermittent temporal aches and blurry vision for over a month. He had a history of stroke and hyper- tension but no past ophthalmological history. A pale optic disc, raised inflammatory markers, and temporal artery biopsy confirmed a diag- nosis of acute arteritic anterior ischaemic optic neuropathy secondary to giant cell arteritis. High-dose intravenous methylprednisolone was administered within 24 hours of presentation, but the likelihood of vision loss reversal was unlikely.
