Polypoidal choroidal vasculopathy: an update on therapeutic approaches.

ABSTRACT: Polypoidal choroidal vasculopathy (PCV) is a retinal disease involving the choroidal vasculature characterized by the presence of polypoidal lesions with or without branching vascular network best seen on indocyanine green angiography (ICGA). Clinical features of PCV include recurrent subretinal hemorrhage; serosanguineous pigment epithelial detachment, subretinal exudation and serous retinal detachment. PCV is more prevalent among Asians and Blacks as compared to Caucasians and has been found to account for 25 to 50% of cases of presumed neovascular age-related macular degeneration in Asian patients. Treatment is indicated in patients with symptomatic PCV due to potentially irreversible visual loss. Various treatment modalities for symptomatic PCV have been described in the literature, including thermal laser photocoagulation, ICGA-guided photodynamic therapy (PDT) with verteporfin, anti-vascular endothelial growth factor (VEGF) therapy, and combined PDT and anti-VEGF therapy. This review aims to provide an update on the therapeutic options for PCV, with particular reference to recent studies published in the past two years.

Project description:BACKGROUND:Polypoidal choroidal vasculopathy (PCV) is one of the disorders within the pachychoroid spectrum diseases. The presence of pachyvessels is one of the characteristics of pachychoroid disorders. However, the relationship between the presence of pachyvessels and the clinical characteristics of PCV eyes has not been determined. The purpose of this study was to determine the relationship between the presence of choroidal pachyvessels and the clinical characteristics of eyes with PCV. METHODS:The medical records of patients who were diagnosed with PCV and were treatment-naïve were reviewed. Fluorescein and indocyanine green angiography, fundus photography, spectral domain optical coherence tomography (SD-OCT), and enhanced depth imaging OCT (EDI-OCT) were used to obtain images of the choroid. The presence of pathologically dilated outer choroidal vessels, pachyvessels, was determined by ICGA images. These pachyvessels were confirmed to correspond with the large choroidal vessels in the EDI OCT images. The PCV eyes were divided into two groups based on the presence or absence of pachyvessels and clinical features and subfoveal choroidal thickness (SFCT) were evaluated between the two groups. RESULTS:Eighty-six eyes of 84 patients with PCV were evaluated. Pachyvessels were detected in 48 eyes (55.8%). The mean SFCT was 203.9?±?83.9??m in all 86 eyes, and it was significantly thinner in eyes with pachyvessels (+) than without pachyvessels (-) (183.2?±?58.4??m vs 230.2?±?103.1??m; P =?0.01). The differences in the incidence of subretinal fluid, pigment epithelial detachments, and hemorrhages between the two groups were not significant. However, the PCV eyes in pachyvessels (+) group with hemorrhage had the thinnest choroid (P =?0.047). The choroidal features of the fellow eyes were similar to those of the PCV affected eyes, that is, the fellow eyes in pachyvessels (+) group had pachyvessels and the fellow eyes in pachyvessels (-) group did not have pachyvessels. CONCLUSIONS:Pachyvessels were presented 55.8% in eyes with PCV, and these eyes had the thin SFCT. The presence of pachyvessels and attenuation of the inner choroid were probably due to the pathological changes in the eyes with PCV.
