Optical Coherence Tomography Angiography for Imaging and Analysis of the Choriocapillaris in Late Age-Related Macular Degeneration
… investigate AMD pathophysiology with a focus on choriocapillaris impairment in macular neovascularization and geographic atrophy, the two subtypes comprising late AMD. The choriocapillaris, the capillary layer of the choroid, is responsible for nourishing the outer retina, including the …

Relationships between subtle ocular changes and microvascular complications in people with type 2 diabetes
… novel biomarkers such as choroid thickness, choriocapillaris perfusion, and retinal capillary perfusion, to ensure collection of high-quality data for aims 1) and 2). Methods: 1) Methodology development: approaches of assessing novel ocular biomarkers were developed and validated with low …

High A-scan rate optical coherence tomography angiography for blood flow speed quantification in the retina
… high blood flow speeds and the centers of choriocapillaris lobules. VISTA OCTA images of eyes with diabetic retinopathy and age-related macular degeneration are also presented. By providing blood flow speed information, the second-generation VISTA aims to enhance and complement traditional …

Structural and functional imaging of the human and small animal eyes using ultrahigh speed Fourier domain optical coherence tomography
… retinal imaging, (4) OCT angiography of the choriocapillaris in the human eye, (5) clinical applications of OCT angiography in retinal diseases, including diabetic retinopathy and age-related macular degeneration, (6) small animal anesthesia protocol for functional hemodynamic imaging, and …

Deep-learning Enabled Accurate Bruch’s Membrane Segmentation in Ultrahigh-Resolution Spectral Domain and Ultrahigh-Speed Swept Source Optical Coherence Tomography
… findings with AMD and DR, such as drusen and choriocapillaris (CC) blood flow deficit, are located adjacent to the Bruch’s membrane (BrM). BrM is a very thin (2–6 µm) extracellular matrix, which is generally not resolved in commercial OCT instrument and therefore challenging to perform …

Potential of endothelial progenitors to reverse choroidal atrophy during age related macular degeneration
Pre-clinically ECFCs have already demonstrated a high potential for revascularisation in a number of models, this makes them an attractive candidate for a number of conditions where impaired blood flow is a factor affecting recovery. However, it is still important to consider the pathology that …

Regulating the bioactivity of placental growth factor in the aging outer retina as a new therapeutic approach to age-related macular degeneration
Age-related macular degeneration (AMD) is a sight-threatening disease caused by degeneration of the macula. Late disease presents as neovascular AMD (NV-AMD) or geographic atrophy (GA). Advances in angiogenesis research have led to the development of treatments for patients with NV-AMD. However, …
