Abstract
Purpose To describe an innovative imaging technique of color editing and 3D volume rendering of optical coherence tomography-angiography (OCT-A) images. Methods Each vascular layer acquired by OCT-A (AngioVue, Optovue) is colored and edited with the GNU Image Manipulation Program. Then a 3D volume rendering of the assessed retinal area is possible, using Adobe After Effect software (Adobe Systems). Results The combined color editing and 3D volume rendering of optical coherence tomography angiography images allow the creation of a short movie displaying the 3D image from chosen angles. Conclusions Image editing and 3D volume rendering is a rather simple technique, which, besides its aesthetic prerequisites, also facilitates simultaneous, distinct visualization of the segmented retinal layers.
