Macular neovascularization types. a–f 3 x 3 mm en face images and corresponding B-scans for the 3 MNV types seen in wet AMD. Segmentation was manually adjusted to reveal the best en face view for each lesion. a,b Type 1 MNV: distinct vascular inlets at the level of the choriocapillaris are seen on en face (a), B-scan reveals flow below the RPE (b, yellow arrow). c, d Type 2 MNV: en face view shows vascular branching suspicious for an MNV (c), B-scan shows flow between the retina and the RPE (d, yellow arrow). e, f Type 3 MNV: en face view shows a small bright tuft (e, white arrowhead), B-scan view shows intraretinal flow trailing downwards, towards the choriocapillaris (f, yellow arrow). Of note, type 3 MNV are very difficult to visualize on en face and often appear only as small, white tufts as depicted in the above example (e)
