This study aims to investigate the incidence and risk factors for the occurrence of posterior ocular ischaemic events (OIE), including retinal vein occlusion (RVO), retinal artery occlusion (RAO) and ischaemic optic neuropathy (ION), in patients with SLE.Methods A national database in Taiwan was used to identify 24 472 patients newly diagnosed with SLE and 244 720 age-matched and sex-matched controls between 1997 and 2012. New occurrences of OIE and confounding factors were recorded. The Kaplan-Meier method was used to compare the risk of OIE between the two groups. Fixed effect models were applied to evaluate the risk factors for OIE.Results The mean age was 36.24±15.82 years and women accounted for 88.4%. Patients with SLE had significantly increased risk of overall OIE (HR 3.89, 95% CI 3.36 to 4.50, p<0.001) as well as each OIE subtype. End-stage renal disease (ESRD; HR 2.91, 95% CI 2.05 to 4.14, p<0.001), hypertension (HR 1.77, 95% CI 1.21 to 2.58, p=0.003) and congestive heart failure (HR 1.67, 95% CI 1.12 to 2.48, p=0.01) were associated with RVO development. Hypertension (HR 2.89, 95% CI 1.10 to 3.96, p=0.02) and ischaemic stroke (HR 3.58, 95% CI 1.97 to 6.48, p<0.001) had increased risk of RAO. ESRD was associated with ION (HR 3.03, 95% CI 1.41 to 6.51, p=0.004). Intravenous steroid was associated with RVO development (HR 2.54, 95% CI 1.67 to 3.84, p<0.001).Conclusions SLE increases the risk of developing OIE. Systemic comorbidities and higher dosage of steroid in patients with SLE are associated with severe ocular ischaemic complications.Data are available upon reasonable request.
