Abstract: Very poor (hand motion or worse) visual acuity at presentation is highly unusual in non-arteritic anterior ischaemic optic neuropathy. We retrospectively reviewed the medical records of 151 consecutive non-arteritic anterior ischaemic optic neuropathy patients seen at our institution between July 2014 and April 2016 to evaluate the frequency and characteristics of patients with very poor visual acuity in non-arteritic anterior ischaemic optic neuropathy. Hand motion or worse visual acuity was documented in 17 patients (11%); all patients had at least one vascular risk factor and 14 (82%) had at least two vascular risk factors. Although severe vision loss at presentation does occur in non-arteritic anterior ischaemic optic neuropathy, an extensive workup should be obtained to rule out another cause, especially arteritic anterior ischaemic optic neuropathy.
