Polypoidal Choroidal Vasculopathy
Introduction Polypoidal Choroidal Vasculopathy (PCV), first described by Yannuzzi et al1 in 1982, is a distinct clinical entity characterized by persistent recurrent serous leakage and hemorrhage in the macula, and is seen in the elderly population. The disorder was poorly understood earlier and had been described by various authors as recurrent pigment epithelial detachment (PED) and posterior uveal bleeding syndrome.2.5 The primary abnormality, as described by Yannuzzi et al,1, 2, 6involves the choroidal circulation, and the characteristic lesion is an inner choroidal vascular network of vessels ending in an aneurysmal bulge visible clinically as a reddish-orange spheroidal polyp like structure. More recently with improvement in choroidal imaging using Enhanced Depth Imaging and Swept-Source optical coherence tomography (EDI-OCT and SS-OCT), PCV is regarded as a part of the Pachychoroid spectrum of diseases and a variant of Type I choroidal neovascularization.7, 8, 9 Epidemiology The
