Retinal vascular caliber associated with cardiac and renal target organ damage in never-treated hypertensive patients.

Objective: The aim of this study was to assess the relationship between retinal vascular caliber and target organ damage in HT patients.

Methods: Data were collected on cardiac, renal, vascular, and retinal variables in 88 consecutive never-treated HT subjects. Retinal vascular calibers were measured from fundus photographs by using a semi-automated computer-assisted program and summarized as CRAE and CRVE.
