Relationship between Retinal Vascular Occlusions and Cognitive Dementia in a Large Cross-Sectional Cohort - 13/07/21
Résumé |
Purpose |
To examine the association between cognitive dementia and retinal vascular occlusions.
Design |
A retrospective, cross-sectional study.
Methods |
Single-institution study population: we reviewed the electronic medical records of 37,208 individuals older than 65 years of age who were evaluated by an ophthalmologist or an optometrist and who also had a medical visit to our institution over a 6-year period. Individuals with and without retinal vascular occlusions were identified by International Classification of Diseases, version 10 (ICD-10) diagnostic codes.
Main outcome |
we analyzed the association between dementia and retinal vascular occlusions after adjusting for covariates which included age, sex, stroke, diabetes mellitus, and hypertension using multiple logistic regression analyses.
Results |
Compared to subjects without retinal vascular occlusions, those with retinal vascular occlusions had a higher prevalence of dementia (6.7% vs. 9.3%, respectively; P < .001). After adjusting for either age or stroke, there were no significant associations between retinal vascular occlusions and dementia.
Conclusions |
Individuals with retinal vascular occlusions have a higher prevalence of dementia. However, this association is secondary to shared underlying risk factors in this population, such as older age and stroke.
