Different IBOOLO dermatoscope models come with different lighting modes. The IBOOLO mini dermatoscopes DE-300 and DE-400 only have two lighting modes: white polarised and white non-polarised light. The handheld dermatoscopes DE-3100 and DE-4100, however, offer a more diverse range of lighting modes. In addition to the two aforementioned modes, they also feature white amber polarised light, amber light, and white amber non-polarised light, which can meet a variety of usage requirements.
What is Polarised Light and Non-Polarised Light in Dermatoscopy?
Polarised and Non-polarised light are the two basic modes of illumination used in dermoscopy. Non-Polarised contact dermoscopy requires the use of a contact solution to reduce reflections in order to examine superficial skin structures from the epidermis to the epidermal-dermal junction. Polarised dermoscopy, on the other hand, reduces reflections by blocking reflected light from the surface of the skin through cross-polarization techniques to better visualize deeper skin structures such as the epidermal-dermal junction and the superficial dermis. Polarised light is critical in dermoscopy because it enhances the visibility of certain skin features and is one of the most important modes of illumination.
Why is Polarised Light Important in Dermatoscopy?
All IBOOLO dermatoscope models except the first generation DE-200 are paired with polarised and non-polarised light. Polarised light offers several advantages in dermatoscopy. It doesn’t require direct skin contact or a contact liquid, making it suitable for examining infected or tender areas. The lack of pressure from non-contact polarised dermatoscopy preserves the skin’s geometry and circulation, aiding in the detection of small vascular structures. Polarised light is particularly effective in visualising deeper skin layers, such as the dermo-epidermal junction and superficial dermis. It can highlight structures like dermal vessels, pink/red colours, and white shiny structures, which are often associated with conditions like basal cell carcinoma. Additionally, polarised light can increase the sensitivity for detecting amelanotic melanoma or structure-poor melanoma, as it can better visualise blood vessels, vascular blush, and white shiny lines.
How Does IBOOLO’s Polarised Light Mode Work?
IBOOLO’s polarised light mode uses cross-polarisation filters. The source light is initially polarised with the first filter, and the reflected light from the skin is blocked by the second filter. This technique significantly reduces glare and allows for better visualisation of deeper skin structures. In this mode, the dermatoscope can be used in both contact and non-contact ways. When in contact with the skin, a contact liquid is not mandatory, which is convenient for examining various skin lesions. The polarised light mode is especially useful for viewing structures in the deeper layers of the skin and can help in the diagnosis of conditions like basal cell carcinoma, dermatofibroma, and some cases of melanoma.
Can IBOOLO’s Amber Polarised Light Enhance Pigment Contrast?
Yes, IBOOLO’s Amber polarised light can enhance the visualisation of pigmented structures within skin lesions. The Amber polarised light boosts the contrast of skin pigments, making it easier to observe features like the blue-white veil and Milia-like cysts. This lighting mode combines the benefits of polarised light in reducing glare and visualising deeper structures with the enhanced pigment contrast provided by the Amber wavelength. This combination is particularly useful for evaluating pigmented lesions and can improve the diagnostic accuracy for conditions like melanoma.
Is UV Light Useful in IBOOLO Dermatoscopy?
IBOOLO incorporates UV light (365nm) into its dermatoscope, offering Wood-mode capabilities. UV light in dermatoscopy can reveal fluorescing features that are not easily visible under visible light. It is especially useful for assessing the efficacy of acne treatment by visualising porphyrins produced by acne-causing bacteria. Furthermore, UV light can help discover exciting presentations of pigmented, vascular, or inflammatory lesions. It is also valuable in visualising bacterial and fungal infections on the skin, nails, or mucosa. With IBOOLO’s UV light mode, practitioners can gain additional diagnostic insights and evaluate a broader range of skin conditions. Currently only the DE-3100 PRO and DE-4100 PRO have built-in UV light illumination. However, in the upcoming DE-500 and DE-5100, the regular versions will also have UV light capability.
How Can IBOOLO’s Various Lighting Modes Improve Diagnostic Accuracy?
IBOOLO’s advanced lighting modes—polarized (white/amber), non-polarized, and UV—offer a multi-layered approach to skin analysis. By understanding how each mode interacts with skin structures, clinicians can unlock deeper diagnostic insights, from early melanoma detection to infectious disease management. For example, the combination of polarised and non-polarised light can reveal both superficial and deeper structures, enhancing diagnostic confidence. The enhanced pigment contrast offered by amber polarised light aids in the early detection of pigmented lesions, while UV light provides additional insights into conditions like acne and infections. These varied lighting modes allow for a more thorough evaluation of skin lesions, enabling healthcare professionals to make more accurate diagnoses and develop more effective treatment plans.
