Sudden onset of neurological visual loss is often vascular in aetiology and includes cerebrovascular disease (TIA and stroke). Subacute onset is more suggestive of infective or inflammatory causes, such as optic neuritis. Gradual or worsening vision loss is more consistent with a degenerative pathology or a space-occupying lesion.
