Phototoxicity in Live Fluorescence Microscopy, and How to Avoid It
BioEssays, 2017 Phototoxicity frequently occurs during live fluorescence microscopy, and its consequences are often underestimated. Damage to cellular macromolecules upon excitation light illumination can impair sample physiology, and even lead to sample death.

Drug-Induced Phototoxicity: A Systematic Review
Journal of the American Academy of Dermatology, 2018 BACKGROUND: Phototoxicity has been attributed to numerous oral drugs over the past 60 years. OBJECTIVE: Determine the quality of evidence supporting suspected phototoxicity from oral drugs.

Phototoxicity of chlorpromazine
Journal of Medicinal Chemistry, 1979The constitution of chlorpromazine has been studied in the context of its phototoxicity. Electron transfer from the side chain to the aromatic nucleus of the drug contributes to its instability to light. Even without the side chain, however, chlorophenothiazines appear to be very photolabile, so that it is unlikely that nonphototoxic analogues of ...

Phototoxic retinal lesions are a product of advances in operative technology. Use of more powerful light sources in both anterior and posterior segment cases and an increase in surgical complexity requiring longer operative times (especially during ophthalmic training) have rendered photic injury a real danger for all surgeons.

Metalloporphyrin phototoxicity
Journal of Photochemistry and Photobiology B: Biology, 1990The phototoxicities of six metalloporphyrin dimethylesters (i.e. cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni), tin (Sn) and zinc (Zn) were investigated. Hemolysis of human erythrocytes and inactivation of two enzymes (acetylcholinesterase and beta-galactosidase) were used to assess the phototoxic efficacy of these metal chelates.

The human eye is constantly exposed to sunlight and artificial lighting. Therefore the eye is exposed to UV-B (295-320 nm), UV-A (320-400 nm), and visible light (400-700 nm). Light is transmitted through the eye and then signals the brain directing both sight and circadian rhythm. Therefore light absorbed by the eye must be benign.

Although the occurrence of iatrogenic light-induced retinal toxicity is beyond doubt, several issues remain to be studied further. These include conflicting reports regarding the wavelength of light that is most hazardous; what mechanism contributes more significantly in the pathogenesis of light-induced retinal toxicity-photochemical or photothermal ...

Shades of phototoxicity in fluorescent imaging agents (that are not supposed to be phototoxic)
Photochemistry and Photobiology, 2023AbstractThis article is a highlight of the paper by Huang et al. in this issue of Photochemistry and Photobiology. It describes shades of phototoxicity in fluorescent imaging agents that are not intended to be phototoxic. Phototoxicity was assessed using a modified neutral red uptake (NRU) in vitro assay with mean photo‐effects (MPE) for the ...
