Optical coherence tomography angiography (OCTA) is a novel imaging technology that enables noninvasive visualization of the retinal and choroidal microvasculature. OCTA enables quantification of microvascular changes in the retinal capillary plexus and choriocapillaris, in addition to qualitative feature description.

2024年2月26日 · Recent advances in optical coherence tomography angiography (OCTA) have enabled quantitative analysis of the retinal and choroidal microvasculature. Decreased retinal and choroidal vessel...

2022年4月19日 · Purpose: We investigated the chorioretinal microvascular changes in patients with retinitis pigmentosa (RP) by optical coherence tomography angiography (OCTA). Methods: Twenty-six patients (52 eyes) affected by RP were compared with 19 healthy controls (38 eyes). OCTA 3 mm × 3 mm macular scans were …

Purpose: To investigate flow area changes measured using optical coherence tomography angiography (OCTA; RTVue XR Avanti ®) in patients with retinitis pigmentosa (RP) with preserved visual acuity (VA). Methods: This was an age- and refraction-matched case-control study. Consecutive patients with a best-corrected visual acuity (BCVA) of ≥20/ ...

Colour Doppler flow imaging (CDFI) and OCTA parameters revealed a significant reduction in RP patients when compared to the controls. OCTA can detect vision-related microvascular and thickness changes around the macula between high- and low-vision groups, which happen earlier than the changes in lar …

2020年9月29日 · To evaluate choroidal vascular changes, including choriocapillaris (CC) and middle/large choroidal vessels, in retinitis pigmentosa (RP) patients using wide-angle optical coherence tomography angiography (OCTA) and to determine whether changes in the choroidal vascularity have a relationship with visual function and retinal structural changes ...
