Advances in swept-source optical coherence tomography and optical coherence tomography angiography
Advances in Ophthalmology Practice and Research, 2022 The fast development of swept-source optical coherence tomography (SS-OCT) and swept-source optical coherence tomography angiography (SS-OCTA) enables both anterior and posterior imaging of the eye. These techniques have evolved from a research tool to an essential clinical imaging modality.The longer wavelength and faster speed of SS-OCT and SS-OCTA ...

Optical Coherence Tomography Angiography in Diabetes
Asia-Pacific Journal of Ophthalmology, 2021 The introduction of optical coherence tomography angiography (OCTA) has significantly improved our knowledge on the ocular vascular alterations occurring in diabetes. In this article, we will provide a review of the prominent OCTA findings in diabetes. In details, OCTA demonstrated that both the retinal vessels and the choriocapillaris are affected in ...
