Key clinical point: Patients with migraine, migraine with aura (MA), or migraine without aura (MO) faced a significantly higher risk for retinal vascular occlusion.
Major findings: Compared with control individuals without migraine, those with migraine (adjusted hazard ratio [aHR] 1.69; 95% CI 1.57-1.83), MA (aHR 1.77; 95% CI 1.58-1.98), or MO (aHR 1.92; 95% CI 1.64-2.25; P < .001 for all) had a significantly higher risk for retinal vascular occlusion. The risk was, however, reduced in the migraine population that received nonsteroidal anti-inflammatory drugs (aHR 0.19; 95% CI 0.16-0.22), propranolol (aHR 0.73; 95% CI 0.62-0.86), or flunarizine (aHR 0.84; 95% CI 0.76-0.93; P < .001 for all).
Study details: This population-based retrospective cohort study included 628,760 patients with migraine and 628,760 control individuals without migraine.
