Associations Between the Retinal/Choroidal Microvasculature and Carotid Plaque in Patients with CHD: An Optical Coherence Tomography Angiography Study
To investigate the associations between retinal/choroidal microvasculature and carotid plaque in patients with CHD assessed by optical coherence tomography angiography (OCTA).
This study included 127 CHD patients with and 79 without carotid plaque. Each patient had both OCTA taken and digitized to determine retinal/choroidal thickness, vessel density and flow area and carotid ultrasound for carotid plaque size and stability measurement. SCP, DCP, out retina and choriocapillaris vessel density, out retina and choriocapillaris flow area, and full retina thickness were analyzed in the fovea centered 6 × 6 mm area. The association between OCTA measurements and carotid plaque characteristics in patients with CHD were evaluated.
The duration of hypertension and DM was significantly longer in CHD patients with carotid plaque than that without (p < 0.001). The mean values for vessel density SCP and DCP (except fovea zone), and choriocapillaris na...
