Photodynamic therapy (PDT) involves the induction of endothelial cell death or occlusion of blood vessels. On the basis of this mechanism of action, PDT is used in the treatment of predominant classic choroidal neovascularization (CNV), if the classic component is over 50%, and in myopic CNV. This study describes 2 cases of distinctive, abnormal, large, subretinal new vessels that are thought t...

Photodynamic therapy (PDT) for the treatment of actinic keratosis has been shown to be effective and safe in large clinical trials published in the last 5 years. However, evidence has since emerged that raises questions or that introduces new issues, such as the management of field cancerization, fluorescence diagnosis and results in transplant recipients. There also remains a need for more stu...

Photodynamic sensitizers are drugs activated by light of a specific wavelength and are used in the photodynamic therapy (PDT) of certain diseases. Second- and third-generation photosensitizers with improved PDT properties are now under investigation. In this issue of the British Journal of Pharmacology, Leung et al. have described the synthesis and investigation of a second-generation photosens...

Photodynamic therapy (PDT) is a relatively new cytotoxic treatment, predominantly used in anticancer approaches, that depends on the retention of photosensitizers in tumor and their activation after light exposure. This technology is based on the light excitation of a photosensitizer which induces very localized oxidative damages within the cells by formation of highly reactive oxygen species, ...

Abstract Owing to strong and tunable surface plasmon resonance (SPR) effect good biocompatibility, gold nanoparticles have been suggested be a versatile platform for broad range of biomedical applications. In this study, new nanoplatform thermo-responsive polymer encapsulated nanorods incorporating indocyanine green (ICG) was designed couple the photothermal properties (AuNRs) photodynamic ICG ...

We report the clinical course of photodynamic therapy (PDT) in a patient with drusenoid pigment epithelium detachment (PED). A patient with drusenoid PED underwent PDT follow-up was carried out at one week, one month, three months, six months and one year after treatment. Fundus exam, optical coherence tomography (OCT) and fluorescein angiography were performed. After the PDT, drusen and PED we...

The increase in the number of basal cell carcinoma (BCC) lesions has prompted use minimally invasive therapies, including Photodynamic therapy (PDT). . objective present work was to analyze efficacy methyl aminolevulinate-mediated photodynamic (MAL-PDT) patients suffering from superficial or nodular BCCs. A total 220 BCC (76 and 144 nodular), clinically diagnosed confirmed by histopathology ana...

Photodynamic therapy (PDT) using photosensitizer can induce diverse cellular responses, including apoptosis. Recently, it has been reported that PDT using methylaminolaevulinate may be effective in basal cell carcinoma. However, it is largely unknown whether PDT using a natural product such as curcumin can induce apoptosis in skin cancer. In this study, to confirm the photodynamic effect of cur...

Photodynamic therapy (PDT) is a minimally-invasive surgical tool successfully targeting premalignant and malignant disorders in the head and neck, gastrointestinal tract, lungs and skin with greatly reduced morbidity and disfigurement. The technique is simple, can commonly be carried out in outpatient clinics, and is highly acceptable to patients. The role of photodynamic therapy in the managem...
