This study compares risk factor profiles for thromboembolism among patients with retinal artery occlusion (RAO) and stroke, respectively. The study found a stronger association between RAO and atrial fibrillation, arterial hypertension, peripheral artery disease, retinal vein occlusion, cataract, and glaucoma, while the associations with diabetes, heart failure, ischemic heart disease, and renal disease were weaker.
Background: Retinal artery occlusion (RAO) has been considered a stroke equivalent. This study compares risk factor profiles for thromboembolism among patients with RAO and stroke, respectively. Methods: This case-control study is based on 5683 RAO patients entered in the Danish National Patient Register between 1st of Janu-ary 2000 and 31st of December 2018. Cases were matched on sex, year of birth, and age at event with 28,415 stroke patients. The Danish nationwide registries were used to collect information about age, sex, previous diagnoses, and drug prescrip-tions. Adjusted conditional logistic regression models were used to investigate the association between hypothesised risk factors and the patient outcome. Results: For atrial fibrillation, a substantially stronger association to stroke was found, with an odds ratio (OR) of 0.52 (95% CI: 0.47-0.58) when comparing RAO patients with stroke patients. RAO was stronger associated with arterial hypertension, peripheral artery disease, retinal vein occlusion, cataract, and glaucoma with OR's ranging from 1.21-11.70. The identified effect measures reached equivalence or was close to equivalence for diabetes, heart failure, ischemic heart disease, and renal disease. Conclusion: The differences in risk factor profiles between RAO and stroke suggests differences in the pathophysiology of the two diseases. These variations in patho-physiologies between the two diseases may indicate that different interventions are needed to ensure the optimal long-term prognosis for the patients.(c) 2022 The Author(s).
