To suggest a clinical distinction between idiopathic typical polypoidal choroidal vasculopathy (PCV) and secondary polyps associated with late AMD and its therapeutic application.Retrospective case series of 30 eyes of 30 consecutive patients (xx females and xx males) with PCV. Initial diagnosis was based on SLO-ICGA, associated with FA and EDI SD-OCT, which allowed a clinical distinction between two subtypes of polyps. This multimodal imaging and visual acuity testing were repeated then at regular follow-up visits. The central macular and choroidal thickness, presence and number of hyper-reflective dots in retina and in choroid were also evaluated.The two groups were clinically different, based on demographic and ethnical characteristics, imaging findings and topography of lesions, presence of drusen, of true CNV, and changes in choroidal thickness. Therapeutic response was different in the two groups. After treatment, hyper-reflective dots decreased significantly but choroidal morphology did not change significantly. Functional and anatomical changes after treatment are analyzed and discussed.The clinical distinction between idiopathic typical PCV and secondary polyps associated with late AMD and results of treatment, sugges |
