What is Wood’s Lamp?

Woods lamp, a super useful tool to diagnose skin diseases for puppy at home or at hospital.

Wood lamp is a diagnostic tool used in dermatology to help identify various skin conditions and infections. It emits long wave ultraviolet (UV-A) light, which causes certain substances and organisms on the skin to fluoresce or glow, helping to diagnose and evaluate skin abnormalities.

Use of Wood lamp in dermatology:

  1. Diagnosis of fungal infection Ringworm capitis: Certain scalp fungal infections, such as those caused by microspora, emit greenish-yellow fluorescence under Wood lamp. Tinea versicolor: This superficial fungal infection fluoresces yellow-green or coppery orange.
  2. Detect bacterial infection ringworm rubus: Caused by Corynebacterium parvus, this disease appears as reddish-brown patches in the scrub area that glow coral red under wood lights.
  3. Identify pigment disorder vitiligo: Under wood lamp, the pigment loss area will appear bright white or blue-white, in sharp contrast to normal pigmented skin. Melasma and other pigmentation: Under a Wood lamp, pigmented areas appear darker, helping to distinguish the depth of pigmentation (epidermis versus dermis).
  4. Assess skin damage and condition Pseudomonas infection: Wounds or burns infected with Pseudomonas aeruginosa will glow green under a wood lamp. Porphyria: Some types of porphyria can cause urine and teeth to fluorescein red under a wood lamp.
  5. Beauty and aesthetic assessments Detect skin changes: It helps to assess the extent of sun damage, acne, and other skin conditions that may not be visible to the naked eye.
