Clinical features and classification framework of polypoidal choroidal vasculopathy in Saudi populations.

Introduction: The Changes in visual acuity(VA) can be caused by polypoidal choroidal vasculopathy(PCV), a subtype of macular neovascularization which is characterized by the formation of polyp-like structures under the retinal pigment epithelium. PCV has been commonly found concurrent with the neovascular age-related macular degeneration (nAMD), which has led to the debate regarding whether, it should be viewed as an independent entity or as a subset of nAMD. The insight into the clinical features of PCV and its therapeutic response such as understanding the prognosis of this disease is very crucial for management and better outcomes.
