简介：
Overview
This study evaluates the relationship between vessel and perfusion density in the parafoveal superficial capillary plexus. It aims to identify the contribution of larger vessels to overall perfusion density, which can indicate vascular health.
Key Study Components
Area of Science
- Neuroscience
- Ophthalmology
- Vascular Biology
Background
- Vasodilation can be a response to clinical pathologic conditions.
- Optical coherence tomography metrics are used for evaluation.
- Identifying vasodilation may reveal low oxygenation in retinal diseases.
- Early detection can occur before clinical signs manifest.
Purpose of Study
- To assess the contribution of larger vessels to perfusion density.
- To utilize optical coherence tomography for indirect assessment of vasodilation.
- To improve understanding of retinal vascular diseases.
Methods Used
- Selection of retinal analysis menu in OCTA device.
