a Fundus photograph showed the greyish-white ERM. b OCT (10 o’clock position) showed an irregularly folded epiretinal membrane (the “spaghetti sign”) with edema. The nasal side of the macula showed a slight PED and a small amount of subretinal fluid. c,d One month after vitrectomy with ERM peeling, a significant increase in the height of PED was shown in the fundus and OCT, with orange polyps near the sub-temporal vessels. e ICGA showed focal hyperfluorescent lesions at the nasal border of the PED lesion. f After one injection of intravitreal ranibizumab, the height of the PED was decreased. g After four monthly injections of intravitreal ranibizumab, PED persisted. h After focal laser therapy targeted to the polyps combined with ranibizumab, PED was absorbed
