Good cardiovascular health may prevent ocular diseases

Posted on

Good cardiovascular health is associated with lower odds for ocular diseases, according to a study published in the American Journal of Medicine.

Approximately half of the 2.2 billion cases of vision impairment or blindness could have been prevented, according to the study. Many ocular diseases have common characteristics that overlap with risk factors for cardiovascular diseases.

In this study, data from 6118 adult ages ≥40 years who participated in the National Health and Nutrition Examination Survey (NHANES), were included. Utilizing the American Heart Association’s prescription for health called the Life’s Simple 7 (LS7) metrics, scores were determined based on information regarding smoking, physical activity, body mass index, diet, blood pressure, total cholesterol, and blood glucose, with a highest possible score of 14 indicating the most ideal cardiovascular health.

Participants had an average age of 57 years. When LS7 scores increased by 1 unit, there were reduced odds for age-related macular degeneration, diabetic retinopathy, cataract, and glaucoma. Multivariable adjustment found the associated was limited to only diabetic retinopathy.
