Pet Wood lights L1
A Wood’s lamp examination is a procedure that uses transillumination (light) to detect bacterial or fungal skin infections. It also can detect skin pigment disorders such as vitiligo and other skin irregularities.
This procedure can also be used to determine if you have a corneal abrasion (scratch) on the surface of your eye. This test is also known as the black light test or the ultraviolet light test.
How Does It Work?
A Wood’s lamp is a small handheld device that uses black light to illuminate areas of your skin. The light is held over an area of skin in a darkened room. The presence of certain bacteria or fungi, or changes in the pigmentation of your skin will cause the affected area of your skin to change color under the light.
Application:
The Wood lamp is safe and does not damage the skin or cause sunburn. The examination is usually very brief and unlikely to cause harm even in light-sensitive individuals. The recommendation is for patients to close their eyes when during exposure to a Wood's lamp. A positive result is when there is a pigmentary disorder that is obvious, or the fluorescence is noted.
The Wood's lamp is often used to make a diagnosis of the following skin disorders:
● Disorders of pigmentation like melasma, vitiligo
● Pityriasis versicolor which presents as a rash on the chest or back - the rash will emit an orange glow.
● Tinea capitis will reveal areas of baldness, and the Microsporum species will fluoresce blue-green - however, many other fungal infections may not fluoresce with Wood's lamp.
● Scabies and head lice
● Erythrasma caused by Corynebacterium which presents as pigmented rash in the skin folds
● Pseudomonas which will fluoresce green
Wood lights are used in a wide range of applications, it is also used to look for signs of porphyria in erythrocytes, stool, and urine. Sometimes beauticians may assess for skin imperfections and signs of aging with a Wood's lamp. When a slit lamp is unavailable, the ophthalmologist may use the Wood lamp to search for scratches and foreign bodies in the cornea.
