AB  - Purpose Our aim was to describe the visual outcomes and determine the clinical factors in ischaemic retinal vasculitis (IRV) that were predictive of a poor visual prognosis or infectious aetiology.Methods Retrospective cohort study of consecutive presentations of IRV to Auckland District Health Board from 2009 to 2022.Results The median age at presentation was 39.2 years and 108 (53.7%) were women. The total median follow-up was 4.8 years. Infectious aetiology was present in 151 eyes (52.1%). Moderate visual loss (20/50 to 20/200) occurred in 20 eyes (6.9%) and severe visual loss (≤20/200) occurred in 41 eyes (14.1%). Median visual acuity was 20/30 (IQR 20/25 to 20/100) on presentation and 20/25 (IQR 20/20 to 20/50) at final follow-up. Retinitis (HR 4.675 p=0.048) and cystoid macular oedema (CME) (HR 7.265 p<0.001) were significantly associated with vision loss. There was concurrent macular ischaemia in 26 eyes (19.4%) and CME in 52 eyes (17.9%). Retinitis was predictive of infectious aetiology (p=0.006) and cotton wool spots for non-infectious aetiology (p<0.001). Retinal haemorrhage (HR 5.580 p=0.001), retinal vein occlusion (HR 5.071 p=0.001) and quadrants of ischaemia (HR 2.222 p=0.025) were significantly associated with vitreous haemorrhage.Conclusion In patients with IRV, 21% of affected individuals sustained moderate-to-severe vision loss over 5 years. Ultra-widefield fluorescein angiography can be used to quantify the risk of neovascular complications and guide treatment.Data are available upon reasonable request. Not applicable.
