Jay Chhablani, MD, explains how 3D choroidal vessel segmentation transforms ophthalmology, enhancing disease diagnosis and treatment through advanced imaging technology.

OCT angiography, or OCT-A, was recently developed to provide three-dimensional noninvasive viewing of the retinal and choroidal vasculature and blood flow estimation at the microcirculation level.

The defect in the basement membrane allows buds of neovascular tissue from the underlying choroidal vasculature to grow into and under the retina. The vessels are fenestrated and can leak into the ...

Surgical intervention, such as bariatric surgery, may have a favorable outcome on the choroidal thickness in these patients’ eyes. Subclinical changes in retinochoroidal vasculature occur in ...

“It therefore provides unique insight into the exact retinal or choroidal layer and location ... that the images provide a reference of normal vasculature, thus aiding in the identification ...

OCT angiography uses motion contrast imaging, and takes advantage of blood flow to visualize retinal and choroidal vasculature, including retinal capillaries, in high-resolution detail.

This includes: (i) proof of concept early phase trials of immunotherapeutics. (ii) Understanding of immune responses via live in vivo imaging of leukocytes through the retinal and choroidal ...

PCV, a disease of the choroidal vasculature, is present in both men and women of many ethnicities, characterized by detachments of the pigmented epithelium and exudative changes that can commonly ...
