Fig 1.
Example of areas of non-perfusion as determined by angiography fluorescein (FA) and Swept-Source Optical Coherence Tomography Angiography (SS-OCTA) images.
Upper left: early phase FA image. Upper right: OCTA image of the retina slab. Lower left: Extracted annotated areas of non-perfusion from the FA image. Marked with white stars are areas which couldn’t be evaluated due to cotton wool spots and hyperreflective material. Lower right: Extracted annotated areas of non-perfusion from the OCTA image.
Fig 2.
Example of annotated artifacts with flow in the cysts on OCTA images.
On the left is an OCTA image of the retina slab. On the upper and lower right a B-scan of the location marked by the red line. On the upper right the B-scan is shown without perfusion representation, on the lower right with perfusion in red. The white arrows mark the perfusion visible in the cyst.
Fig 3.
Example of annotated artifacts with flow around the cysts on OCTA images.
On the left is an OCTA image of the retina slab. On the upper and lower right a B-scan of the location marked by the red line. On the upper right the B-scan is shown without perfusion representation, on the lower right with perfusion in red. The white arrows mark the perfusion around the cysts. Hyperreflective material is visible surrounding the cysts.
