Abstract
Ischaemic visual loss is often considered a lower risk factor than other transient ischaemic attacks (TIA). We aimed to determine the recurrence risk, prevalence and management of vascular risk factors in these patients. The study took place in the University College Hospital London daily TIA clinic, main referral centre for North-Central London and Moorfields Eye Hospital. Consecutive records for patients with transient (< 24 h) or permanent (> 24 h) ischaemic visual loss were reviewed during the period January 2014-October 2016. Patients diagnosed with temporal arteritis were excluded. Of 400 patients, 224 (56%) were male with mean age 64.5 years (SD 15.1); 263 patients (65.8%) presented with transient and 137 patients (34.2%) with permanent ischaemic visual loss; 51.3% had hypertension (HTN), 35.3% hypercholesterolaemia, 14.5% diabetes, 11.8% ischaemic ocular events, 10.0% ischaemic heart disease, 7.3% atrial fibrillation (AF), 6.3% TIA, 5.3% stroke, and 12.3% were smokers. Median vascular risk factors were 2 (range 1-6), but 122 (30.5%) had ≥3. Those with diabetes (p < 0.001), HTN (p = 0.008), previous myocardial infarction (p = 0.005), or ≥3 vascular risk factors (p = 0.012) were more likely to present with permanent visua...Continue Reading
