Optical coherence tomography angiography (OCTA) of a patient with neovascular AMD reveals a type 1 (sub-RPE) choroidal neovascular membrane. The vascular slab that best visualises this lesion is:

• A Superficial capillary plexus slab
• B Deep capillary plexus slab
• C Radial peripapillary capillary plexus slab
• D Outer retina and choroidal slab (choriocapillaris/outer retina segmentation) ✓

Explanation

OCTA segments the retina into superficial capillary plexus, deep capillary plexus, outer avascular retina, and choriocapillaris. Type 1 CNV (occult) located beneath the RPE is best visualised in the outer retina-to-choriocapillaris slab. Superficial and deep slabs image the inner retinal vasculature; the radial peripapillary slab is relevant for glaucoma assessment.
