Choriocapillaris Flow Deficits in Normal Chinese Imaged by Swept-Source Optical Coherence Tomographic Angiography

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Investigating the macular choriocapillaris in early primary open-angle glaucoma using swept-source optical coherence tomography angiography

“…Our finding on the impact of normal aging on the macular choriocapillaris is in line with previous studies ( 41 – 45 ). Cheng et al ( 41 ) found that a higher density of choriocapillaris flow deficits was associated with older age among 830 healthy Chinese individuals who were imaged using SS-OCTA.…”

“…Our finding on the impact of normal aging on the macular choriocapillaris is in line with previous studies ( 41 – 45 ). Cheng et al ( 41 ) found that a higher density of choriocapillaris flow deficits was associated with older age among 830 healthy Chinese individuals who were imaged using SS-OCTA. This was also reported by Zheng et al ( 42 ) where the density increased with age, with greatest increase seen in the central 1 mm region of the macula.…”

Retinal Microvasculature and Choriocapillaris Flow Deficit in Relation to Serum Uric Acid Using Swept-Source Optical Coherence Tomography Angiography

“…A recent study has shown that CFD in OCTA is affected by age, blood pressure, and lipid levels, but SUA was not analyzed in the study. 11 The present study found that high SUA led to increased CFD in both men and women after adjusting for other confounding factors. Therefore, SUA should be considered when interpreting CC changes in normal and diseased subjects.…”

“…The CFD was calculated from the ratio of the total area of flow voids to the total area, excluding the area of projection artifacts. 11 …”

“… 10 Furthermore, choriocapillaris flow deficit (CFD) is related to age, blood pressure, and serum lipid levels. 11 …”
