Clinical Trial Summary

This study will evaluate patients with diagnosis of polypoidal choroidal vasculopathy (PCV) in pachychoroid treated with combined therapy, consisting in photodynamic therapy (PDT) and 3 intravitreal therapy (IVT) of Aflibercept monthly. This is a single center, prospective case-series study. The investigators are going to evaluate Corrected Distance Visual Acuity (CDVA), disease activity, retinal and choroidal thicknesses and number of injection per year, during a twelve month follow up. The aim of this study is to verify if the combined therapy can act on the insult induced by the pachychoroid and on the neovascular lesion itself in this sub-population of patients with PCV in pachychoroid,


Description:

This study evaluates patients with diagnosis of polypoidal choroidal vasculopathy (PCV) in pachychoroid treated with combined therapy, consisting in photodynamic therapy (PDT) and 3 intravitreal therapy (IVT) of Aflibercept monthly. Inclusion criteria are the presence of haemorrhagic or exudative PCV diagnosed by Optical Coherence Tomography (OCT) and Indocyanine Green Angiography (ICGA) and the mean central choroidal thickness > 250 µm. Exclusion criteria comprehend ocular comorbidity, previous cardiovascular events and different ocular surgical procedures form cataract surgery. Participants undergo a thorough ophthalmic assessment that included best corrected visual acuity (CDVA), slit lamp biomicroscopy and dilated funduscopic examination. OCT, OCT-Angiography (OCT-A), ICGA and Fluoresceine Angiography (FA) were performed for all patients. The 12-month follow-up foresee monthly revaluations of the above measurements, excluding FA, repeated only on clinical judgement. CDVA will be measured using LogMAR. Choroidal and retinal thicknesses will be automatically measured by digital software OCT- integrated (IMAGEnet). All patients will be treated with a loading dose of Aflibercept combined with PDT within the first 7 days of the first intravitreal therapy. The spot size is calculated by adding 1000 μm to the greater linear dimension of the lesion. No additional therapy will be performed during follow-up unless signs of reactivation.

Study Design


Intervention

Drug:
Aflibercept Injection
Patients will be treated with combined therapy to determine the synergy of this treatment, causing anti- Vascular Endothelial Growth Factor (anti-VEGF) to block neovascular exudation and photodynamic therapy to close aneurismal vessel and reduce choroidal vascular congestion.
