Clinical Trials in PCV
Overview of Disease State
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration (nAMD) located above or within the Bruch membrane that has a high prevalence in people of Asian descent. [Ho.Sci Rep.2016][Oishi.Am J Ophthalmol.2013][Koh.JAMA Ophthalmol.2017] The prevalence has been reported to affect between 10% and 54% in people of Asian descent with nAMD, compared to between 8% and 12% of Caucasian patients with presumed nAMD. [Koh.Retina.2012] Untreated, the long-term prognosis of PCV is poor, with permanent vision loss occurring due to hemorrhage, exudation, macular edema, and disciform scar formation. [Koh.JAMA Ophthalmol.2017] [Lee.Graefes.2017]
PCV is typically characterized by an abnormal subretinal pigment epithelial network of vessels of choroidal origin, ending in aneurysmal dilatations, which appear as spheroidal polyp-like structures. [Koh.JAMA Ophthalmol.2017] Clinically, PCV often presents with subretinal pigment epithelium (sub-RPE) and/or subretinal hemorrhage and fluid accumulation; however, however, the clinical hallmark of PCV is considered to be the presence of orange-red, bulb-like structures growing from the choroid into the subretinal space, with associated adjacent serous pigment epithelial detachment (PED) or overlying neurosensory detachment, with subretinal hemorrhage and lipid (hard) exudates. [Koh.Retina.2012][Agrange.AAO EyeWiki.2021]
The use of anti-vascular endothelial growth factor (VEGF) agents with or without concurrent photodynamic therapy (PDT) has been shown to improve visual and anatomic prognoses. Summarized below are some of the more relevant studies supporting the use of anti-VEGF and/or PDT for PCV.
