Multimodal Imaging of PAMM
OCTA en face imaging reveals hypo-reflective lesions in the areas of PAMM (E). Intermediate/deep retinal capillary dropout may also be seen (G1-3). Occasionally, there will be spontaneous refilling with no dropout visualized.
- OCTA: intermediate/deep retinal capillary dropout. Occasionally, there will be spontaneous refilling with no dropout visualized.
- FA: may be unremarkable without evidence of occlusion (delayed filling). May be helpful to rule out occlusion.
