Ultraviolet-B Damages Corneal Endothelium

Optometry and Vision Science, 1984
Direct in vivo observation of acute ultraviolet (UV)-induced corneal endothelial damage is not possible due to the more severe damage produced in the epithelium. In order to quantify damage and evaluate endothelial recovery an indirect method was used.

Keratopathy after ultraviolet B phototherapy

Wiener klinische Wochenschrift, 2005
Atopic dermatitis is the most common chronic inflammatory skin disease among children in industrialized countries. The prevalence is recorded to be up to 20% in children. Phototherapy with ultraviolet B (UVB) is an effective form of treatment with a low complication rate. Here we report on a patient with atopic dermatitis who underwent UVB treatment to

Narrow-band ultraviolet B phototherapy versus broad-band ultraviolet B or psoralen-ultraviolet A photochemotherapy for psoriasis

Cochrane Database of Systematic Reviews, 2011
The most commonly used types of phototherapy for treating psoriasis are narrow-band ultraviolet B (NB-UVB); broad-band ultraviolet B (BB-UVB), which includes selective (delivering radiation with a wavelength range of 305 to 325 nm) and conventional BB-UVB (280 to 320 nm); and psoralen ultraviolet A photochemotherapy (oral or bath PUVA).

Development of cutaneous tolerance to ultraviolet B during ultraviolet B phototherapy for psoriasis

Photodermatology, Photoimmunology & Photomedicine, 1996
During a schedule of multiple exposures to ultraviolet B radiation (UVB, 280–320 nm), skin develops a reduced sensitivity, variously called tolerance, photoadaptation, accomodation or acclimatization. In this study we have investigated the development of tolerance in the normal skin of a group of psoriatic patients during the course of UVB therapy ...

Ultraviolet-B Effects on Ocular Tissues

Biochemical and Biophysical Research Communications, 1995
The enhancement of UVB on the surface of the earth due to stratospheric ozone depletion may increase the risk of photochemically induced cataract. In this study, changes in the content of certain biological parameters were used as a marker to study ocular toxicity.
