Retinal phantom applicable to OCT, OCT-angiography, and fundus angiography

Design and Quality for Biomedical Technologies XIV, 2021
The retinal imaging system, such as optical coherence tomography (OCT), OCT-angiography (OCTA) and fluorescein angiography (FA), is the important subject for ophthalmic. The use of such equipment continues to increase and retinal phantoms have also been developed to evaluate and modify its performance and image quality.

A Review of OCT Angiography in Glaucoma

Seminars in Ophthalmology, 2019
There is growing evidence that vascular dysfunction plays a role in the pathogenesis of glaucoma. The details of this relationship have remained elusive partially due to limitations in our ability to assess blood flow in the optic nerve. Optical coherence tomography angiography (OCTA) has emerged as a promising new technology well positioned to become ...
