Polypoidal Choroidal Vasculopathy (PCV) (Colour Image, FFA, ICG, OCT)

المَشيمِيَّة -> أمراض وعائية
Female, 60 years of age, BCVA 0.6, IOP 16 mmHg, decrease of VA since 9 months, metamorphopsia, arterial hypertension. (1) Initial fundus photograph shows reddish-orange nodules. (2) Indocyanine green angiography shows a branching vascular network that terminates in polypoidal lesions. (3) A vertical optical coherence tomography section through the fovea reveals sharp protrusions of the retinal pigment epithelium due to polypoidal lesions. A branching vascular network is seen as flat protrusions. Polypoidal choroidal vasculopathy (PCV) is recognized as a distinct clinical entity, differing from exudative AMD. PCV is a branching vascular network that terminates in polypoidal lesions seen on indocyanine green angiography. PCV is more common in Asians than in Caucasians. The treatment effects of anti-VEGF agents on the vascular lesions of PCV are limited in short-term follow-up. In contrast, studies have shown encouraging results of PDT for the treatment of PCV (1,2). The diagnosis of PCV is based on indocyanine green angiography, which shows a branching vascular network terminating in polypoidal dilation.
