Photodynamic therapy (PDT) with verteporfin involves intravenous administration of a photosensitizer followed by its laser light activation at the target site to inhibit aberrant choroidal vascularization. This narrative review provides an overview of the role verteporfin PDT plays in the management of chorioretinal conditions. A PubMed literature review of all English-language articles published through October 19, 2023, was conducted to identify relevant references. Verteporfin PDT has been shown to be safe and effective for the treatment of patients with choroidal neovascularization (CNV) due to neovascular age-related macular degeneration and is often used in combination with a vascular endothelial growth factor (VEGF) inhibitor. Additionally, patients with polypoidal choroidal vasculopathy, a subtype of neovascular age-related macular degeneration, also benefit from verteporfin PDT combined with a VEGF inhibitor for improving visual acuity. Verteporfin PDT has also been effective in treating patients with peripapillary CNV, as well as eyes with CNV due to ocular histoplasmosis and pathologic myopia. Reduced dose and/or fluence PDT protocols have been effective in patients with central serous chorioretinopathy while reducing adverse effects. In eyes with choroidal hemangioma, tumor regression and visual outcomes have been improved with verteporfin PDT treatment. Photodynamic therapy with verteporfin continues to play an important role in the management of chorioretinal conditions.

The efficacy of immunotherapy in triple-negative breast cancer (TNBC) is significantly hindered by its low immunogenicity and immunosuppressive tumor microenvironment. Non-invasive photodynamic therapy (PDT) is increasingly recognized as a potential immunotherapeutic stimulant in the treatment of TNBC. However, photodynamic immunotherapy is constrained by tumor hypoxia and excessive inflammation suppression during the course of treatment.

Late diagnosis is one of the major obstacles for the treatment of breast cancer which can be overcome with a system offering sensitive imaging and selective therapeutic effect. In this study, we developed a "dark-bright" multifunctional drug delivery system bringing real-time imaging and non-invasive therapy together. Theranostic ability of the system was delivered by Verteporfin (VP), serving as a fluorescence probe and a photosensitizer.

X-ray-induced photodynamic therapy (XPDT) can penetrate deeply into the tumor tissues to overcome the disadvantage of conventional PDT. However, the therapeutic efficacy of XPDT in cancer therapy is still restricted due to the insufficient reactive oxygen species (ROS) generation at a relatively low irradiation dosage. Herein, we present the tumor pH and ROS-responsive polyprodrug micelles to load the X-ray photosensitizer verteporfin (VP) as an ROS production enhancer.

Anti-vascular endothelial growth factor (anti-VEGF) agents administered as either monotherapy or combination with verteporfin photodynamic therapy (PDT) are the 2 dominant treatment for polypoidal choroidal vasculopathy (PCV); however, controversies remain due to small sample sizes and inconsistency in prognosis from randomized controlled trials (RCTs). In accordance with the PRISMA statement, we investigated the efficacy of PDT plus anti-VEGF combination with anti-VEGF monotherapy. This study was accepted by the International Prospective Register of Systematic Reviews (CRD42023471362).

Tumor hypoxia and elevated intracellular glutathione (GSH) levels significantly compromise the effectiveness of photodynamic therapy (PDT) in treating melanoma. In this study, we synthesized positively charged nanoparticles through a self-assembly method, incorporating photosensitizer verteporfin (VER), mitochondrial respiratory inhibitor atovaquone (ATO), and Fe. Subsequently, the nanoparticles were modified with sodium hyaluronate (HA) to obtain HA-ATO-Fe-VER nanoparticles (HAFV NPs).
