Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.ABSTRACT Objective To evaluate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on the periocular area of canine eyes for preoperative disinfection compared to standard 10% povidone‐iodine (PI) solution preparation. Methods The upper and lower eyelids of six research‐bred beagles were equally divided into two sections (medial ...

Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.ABSTRACT Objective To investigate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on M. bovis using an affordable, broadly available modified handheld device and to determine if photoreactivation plays a role in bacterial resistance to UV‐C. Methods UV‐C therapy (UVCT) was evaluated in vitro using triplicates of 3 M.

The Molecular Perspective: Ultraviolet Light and Pyrimidine Dimers [PDF]
STEM CELLS, 2001 we go about our daily activities. Whenever we walk in the sun, ultraviolet light (UV) attacks our DNA, making chemical changes that corrupt our genetic information. Fortunately, the most dangerous UV light never reaches us at all: the ozone in the upper atmosphere absorbs (at least for now) the energetic UVC wavelengths.

Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.ABSTRACT Objective To assess if an inexpensive, commercially available ultraviolet C (UV‐C) light device with a peak emission of 275 nm can inhibit equine keratomycosis‐associated pathogens located at different corneal depths in an ex vivo model. Methods A controlled, randomized experimental design.
