Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [ 1 ] PDT is used in treating acne , wet age-related macular degeneration , psoriasis , and herpes .

Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
The efficacy of antimicrobial photodynamic therapy, using various distinct photosensitizers, has been studied since the 1990s. [ 9 ] [ 7 ] Most studies have yielded positive outcomes, often achieving disinfection levels, as defined by infection control guidelines, exceeding 5 log 10 (99.999%) of microbial inactivation. [ 14 ]
Photodynamic therapy (PDT) is a well-established clinically practiced protocol in which photosensitizers are used to produce singlet oxygen for destroying diseased or damaged cells or tissues. [2] Optogenetics is another method that relies on light for dynamically controlling biological functions especially brain and neural. [4]
While blue light therapy has similar mechanisms for skin enhancement as red light therapy, its usage for photodynamic therapies in treating cancer are slightly different. Blue light therapy stimulates immune system defences, destroys blood vessels that help cancer cells grow, and causes cell death by reacting with oxygen. [16]
Intense anti-VEGF-therapy, often in combination with a special laser treatment (photodynamic therapy) is effective to restore visual loss and/or slow visual decline. [6] In all stages, focal choroidal excavation may occur, which probably represents a contraction of the choroid due to scarring processes. [7]
