Sequential SDOCT imaging in a 68-year-old female (a) SD OCT illustrating a FIPED of 2277u. Zoomed image illustrates partially hyperreflective fill FIPED with focal loss of ellipsoid zone. Note the large hallers layer vessels (arrows) compressing the sattler and choriocapillaries; pachyvessels underneath FIPED. (b and c) 9^th, 14^th month follow up OCT image shows a lateral elongation of the FIPED by 323u with subsequent SRF, IRF formation. (d and e) ICG taken at 11 and 14 months illustrates dilated choroidal vessels at the foveal zone and small Type 2 interconnecting vascular network respectively

Sequential SDOCT imaging in the right of 59-year-old female, left eye diagnosed as PCV (a) SD OCT illustrating a FIPED of 1986u. Note the peripapillary location. (b and c) 6^th, 12^th month follow up OCT shows expansion of FIPED subfoveally with increase in SRF subsequently. (d) 15^th month follow up SDOCT shows an optically clear PED at the end of expanding of FIPED. (e) 16^th month Eye tracking ICG shows polypoidal lesion at the end of PED. (f and g) ICG taken at 11 and 15 months illustrates dilated choroidal vessels at the foveal zone with a subfoveal polyp and a BVN

Sequential SDOCT demonstrating the gradual expansion of Flat irregular pigment epithelial detachment (FIPED) in the unaffected fellow eye of 63-year-old female diagnosed as PCV (a) SDOCT imaging showing a FIPED located inferior to fovea measuring 1535u. (b and c) 6^th, 8^th month followup OCT showing lateral expansion by 127u and 428u with SRF, IRF formation. (d) Asterisk showing Polypoidal lesion developing at the end of FIPED. (e) ICG at 3^rd month shows normal circulation. (f and g) 8^th month ICG and Eye tracking ICG shows polyp with type 1 BVN with a feeder vessel; BVN corresponding to the FIPED
