En Face Optical Coherence Tomography and Optical Coherence Tomography Angiography Imaging of Taxane-Associated Cystoid Macular Edema

, 2016
The taxanes are chemotherapeutic agents that may, in rare cases, cause cystoid macular edema without leakage on fluorescein angiography. Two patients with evidence of taxane-related macular edema presented and were evaluated using novel en face optical ...

Review of Artifacts and Related Processing in Ophthalmic Optical Coherence Tomography Angiography (OCTA)

Photonics
Optical coherence tomography angiography (OCTA) is a non-invasive imaging modality that can provide rich three-dimensional microvascular information of fundus in ophthalmic imaging. However, various imaging artifacts may be generated during OCTA data acquisition and processing, originating from a number of factors such as multiple light scattering ...

Fractal Analysis of Peripapillary Vasculature In Eyes With Papilledema Using Optical Coherence Tomography Angiography

, 2017
Optical coherence tomography angiography (OCTA) permits non-invasive evaluation of the retinal vasculature, optic nerve head, and peripapillary microvasculature. We aim to quantify the fractal dimension (FD) of eyes with papilledema compared with control
