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.
A Wood lamp is used to identify the extent of pigmented or depigmented patches and to detect fluorescence. Normal healthy skin is slightly blue in colour but shows white spots where there is thickened skin, yellow where it is oily, and purple spots where it is dehydrated. Clothing lint often shines bright white
