Clinical features of flat irregular pigment epithelial detachment associated with choroidal neovascularization in chronic central serous chorioretinopathy

Purpose: To describe the multimodal imaging characteristics of flat irregular pigment epithelial detachment (FIPED) in patients with chronic central serous chorioretinopathy and determine the risk factors for vascularized FIPED and to explore the activity of vascularized FIPED before and after half-dose photodynamic therapy. Methods: Multimodal imaging data of 185 eyes of 155 consecutive patients with chronic central serous chorioretinopathy included spectral domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography. Optical coherence tomography angiography was available for 56 eyes. Flat irregular PED was classified into two types based on indocyanine green angiography or optical coherence tomography angiography findings: avascular FIPED and vascularized FIPED. Results: The avascular FIPED and vascularized FIPED were detected in 127 (68.6%) and 42 (22.7%) eyes, respectively. Age (P = 0.001), visual acuity (P = 0.048), subfoveal choroidal thickness (P = 0.032), height (P
