Polypoidal choroidal vasculopathy (PCV) is an age-related macular degeneration (AMD) subtype and is seen particularly in Asians. Previous studies have suggested disparity in response to intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents between PCV and typical AMD, and thus, the preferred treatment for PCV has remained unclear. Recent research has provided novel insights into the pathogenesis of PCV, and imaging studies based on OCT suggest that PCV belongs to a spectrum of conditions characterized by pachychoroid, in which disturbance in the choroidal circulation seems to be central to its pathogenesis...

Herein, we describe a neovascular age-related macular degeneration patient with retinal angiomatous proliferation (RAP) and polypoidal choroidal vasculopathy (PCV) coexisting in the same eye at the time of diagnosis. A 55-year-old woman presented with a history of decreased vision in her left eye. Fundoscopy, fluorescein and indocyanine green angiography, and optical coherence tomography imaging revealed RAP and PCV lesions in her left eye at first diagnosis. The patient received intravitreal ranibizumab therapy but developed tachyphylaxis after the first dose despite having three monthly doses...

BACKGROUND: Polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) share similar phenotype but are different in clinical manifestations, responses to treatment, and prognosis. Whether PCV is a subtype of AMD or a distinct entity from nAMD remains elusive. Therefore, we performed a whole-exome sequencing (WES) based association analysis to compare the genetic architecture of PCV and nAMD in Han Chinese. METHODS: Whole-exome sequencing analysis was performed on 21 nAMD cases, 20 PCV cases and 20 healthy controls...

We report a case of polypoidal choroidal vasculopathy (PCV) presented with massive submacular hemorrhage (SMH) and macular hole (MH). Spectral domain optical coherence tomography confirmed the presence of MH along with SMH and also revealed an extrafoveal-notched pigment epithelium detachment (PED) suggestive of PCV. Urgent pneumatic displacement with perfluoropropane (C3F8) was done. Indocyanine green angiography done 3 weeks later showed polyps in the superonasal macula corresponding to PED. Extrafoveal polyps were treated with laser photocoagulation...

Purpose of Review: The goal of this paper is to review the recent literature of polypoidal choroidal vasculopathy (PCV) and provide an update on the epidemiology, pathophysiology, clinical findings, and management. Recent Findings: Although indocyanine-green angiography (ICGA) is still the gold standard for diagnosis of PCV, the use of en face optical coherence tomography (OCT) and OCT angiography are useful tools in the diagnosis of PCV. Studies demonstrate superior treatment outcomes with combination photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) therapy...

The term aneurysmal type 1 neovascularization is derived from terminology which is established in the literature but which has fallen out of use. We believe that aneurysmal type 1 neovascularization accurately describes the lesions which define the entity known as polypoidal choroidal vasculopathy. Over the last 3 decades the clinical spectrum of PCV has expanded to recognize the occurrence of the aneurysmal (polypoidal) lesions in different contexts, resulting in a complex and unwieldy taxonomy based sometimes on circumstantial findings rather than mechanistic considerations...

Polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (AMD) are prevalent age-related diseases characterized by exudative changes in the macula. Although they share anatomical and clinical similarities, they are also distinctly characterized by their own features, e.g. vascular abnormalities in PCV and drusen-mediated progression in neovascular AMD. PCV remains etiologically uncharacterized, and ongoing discussion is whether PCV and neovascular AMD share the same etiology or constitute two substantially different diseases...
