Manifestation of fundus angiograph of polypoidal choroidal vasculopathy

Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage, serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA.
