Control of blood pressure and blood glucose levels has important clinical significance to the retina.

ABSTRACT:

Background

To investigate whether blood pressure and blood glucose levels affect retinal microvascular parameters, reflected by density within 300 μm surrounding the avascular area of the fovea (FAZ), also called FD-300.

Methods

A case series study design was used to include patients with essential hypertension and/or type 2 diabetes who were hospitalized in the Department of Geriatrics, Beijing Tongren Hospital, from January 2023 to January 2024. FD-300 was measured via optical coherence tomography angiography. Multivariate linear regression analysis was used to adjust for confounding factors and then explore the influencing factors of FD-300.

Results

Patients were divided into four subgroups according to the quartile of FD-300. The median systolic blood pressure (SB
