Superficial capillary plexus vessel density/deep capillary plexus vessel density ratio in healthy eyes [PDF]

BMC Ophthalmology, 2022
Background To identify factors differently affecting the superficial capillary plexus (SCP) and deep capillary plexus (DCP) in healthy eyes using their vessel density (VD) ratio. Methods Healthy eyes were enrolled. The ratio between the VD of SCP and DCP

Clinical Observation of Macular Superficial Capillary Plexus and Ganglion Cell Complex in Patients With Parkinson’s Disease

Ophthalmic Research, 2023
<b><i>Introduction:</i></b> We investigated macular superficial capillary plexus (SCP) density and the thicknesses of the ganglion cell complex (GCC) in patients with Parkinson’s disease (PD) and correlated them. We also observed the correlations between SCP density and clinical parameters of PD patients.

Macular Vascular Density at the Superficial Capillary Plexus Using the Optical Coherence Tomography Angiography [PDF]

Clinical Ophthalmology, 2019
The aim of this study was to assess the effects of age, gender, axial length and retinal thickness on the vascular density in a normal population using the Optovue optical coherence tomography angiography (OCT-A).A total of 209 eyes of 209 healthy subjects were scanned using the OCT-A on an outpatient basis. Patients were 20-75 years of age.

Reduced Vessel Density in the Mid-Periphery and Peripapillary Area of the Superficial Capillary Plexus in Non-Proliferative Diabetic Retinopathy. [PDF]

J Clin Med, 2022
Our aim in this study was to assess the vessel density (VD) and vessel skeleton density (VSD) in the nasal area of the superficial capillary plexus (SCP) of diabetic subjects without diabetic retinopathy (DR), or in those with a non-proliferative diabetic retinopathy (NPDR), and to evaluate the relationship between the VD and VSD and the severity of DR.

Microvascular Alterations Analysis: Optical Coherence Tomography Angiography Evaluation of Superficial Capillary Plexus in Retinal Vein Occlusion

Bulgarian Review of Ophthalmology
INTRODUCTION: Optical coherence tomography angiography (OCTA) is a method used to detect microvascular changes occurring in the capillary plexuses of the retina in individuals with retinal vein occlusions (RVOs). It enables the quantitative evaluation of parameters related to the vascular network of the macula.AIM: The aim of this article is to ...
