polarized light dermoscopy: for clearer skin lesion screening - IBOOLO

polarized light is key in dermoscopy devices for skin lesion screening. IBOOLO-polarized dermatoscopes block surface reflections and clearer observation of subsurface skin anatomy for diagnoses.

The Benefits of polarized Light in Dermoscopy Skin Exams

Dermoscopy, the technique of using a specialized magnifying device called a dermatoscope to visually examine the skin, allows doctors to see subsurface structures not visible to the naked eye. This provides valuable clues in assessing moles, lesions, and other skin abnormalities at an early stage. Recent advances in optics utilize polarized light dermoscopy to increase the accuracy of skin evaluations. Keep reading to understand why polarized dermatoscopes and polarized dermoscopy lead to better detection and analysis.

What is polarized Dermoscopy Better For?

polarized dermatoscopes contain specialized filters that help eliminate surface reflections and glare from light hitting the skin at sharp angles. This allows true colors and structural details within the skin to shine through more clearly so they can be assessed properly. Studies show polarization in polarized light dermoscopy reduces image artifacts that can obscure key visual clues used for detecting problem areas on the skin. Overall, polarized dermoscopy provides superior visual accuracy for identifying early signs of skin cancer and other lesions because subtle visual indicators are not washed out by glare.

Modern smartphone dermatoscope attachments designed specifically for skin exams use polarized light dermoscopy for this reason. They deliver detailed skin magnification up to 30x or more along with built-in polarization filters to enable high-resolution monitoring of spots and moles. Consistent periodic self-checks with a polarized smartphone dermatoscope allows you to detect subtle changes early for better health outcomes.

What are the Different Types of Dermoscopy?

There are two main techniques and types of dermoscopes based on the light source they use:

1. Non-polarized light dermoscopy uses traditional white LED light. This helps see colors and structures, but can still result in surface reflections.

2. polarized light dermoscopy uses specialized filters to eliminate glare and reveal what's under the skin more accurately. There are two implementations of polarization:

  • Linear polarization with one filter
  • Circular polarization with two rotating filters

In general, polarized dermoscopy is considered superior for visualizing the subsurface skin. Leading smartphone dermatoscopes now incorporate polarized light for easy skin checks at home.

Additionally, there are dermatoscopes optimized for specific use cases:

  • Contact polarized dermatoscopes with a plate that touches the skin to see a targeted area.
  • Non-contact polarized dermatoscopes held at a short distance above the skin to examine a broader area.
  • Hybrid polarized dermatoscopes that convert between contact and non-contact modes.

What is the Difference Between Dermlite and Heine Dermatoscope?

Both Dermlite and Heine are respected brands producing high-quality polarized dermatoscopes. The key differences come down to:

1. Light Source

  • Dermlite uses polarized light to increase subsurface visibility.
  • Heine has specialty models with polarized and non-polarized light.

2. Lens Options

  • Dermlite emphasizes magnification power up to 75x.
  • Heine offers a broader range of magnification levels.

3. physical Design

  • Dermlite has compact polarized dermatoscopes good for travel.
  • Heine provides both portable and cart-based polarized models.

In the end, both brands of polarized dermatoscopes allow doctors to examine the skin accurately for abnormalities and are trusted by dermatology practices. When it comes to accessible home use, smartphone polarized dermatoscopes have made self-checks with polarized light dermoscopy, high-magnification optics simple and affordable for monitoring skin health.

The specialized lighting and magnification capabilities of modern polarized dermatoscopes - whether used by doctors or consumers - provide invaluable assistance when it comes to seeing what's under the skin for early detection using polarized dermoscopy. Understanding your options ensures you have the right tools for detailed skin screening.

Cleaning your dermoscopy after usage is important to prevent cross-contamination and infection. The cleaning method may vary depending on the type and model of your dermoscopy, so you should always follow the manufacturer’s instructions. However, some general steps are:

• Turn off and disconnect your dermoscopy from any power source or device.

• Wipe off any visible dirt or debris from the dermoscopy with a soft cloth or tissue.

• Disinfect the dermoscopy with an alcohol-based wipe or spray, or a disinfectant solution recommended by the manufacturer. Make sure to cover all surfaces, especially the lens and contact plate.

• Let the dermoscopy air dry completely before storing it in a clean and dry place.

• Do not use abrasive or corrosive cleaners, solvents, or detergents that may damage the dermoscopy.

• Do not immerse the dermoscopy in water or any liquid, unless it is waterproof and designed for immersion.

You should clean your dermoscopy after each use, or at least once a day if you use it frequently. You should also check your dermoscopy regularly for any signs of damage or malfunction, and contact the manufacturer or service provider if needed.

A dermoscopy is a device that allows the examination of skin lesions with magnificationand illumination. By revealing subsurface structures and patterns that are not visible tothe naked eye. It can improve the diagnose accuracy of skin lesions, such as melanoma,basal cell carcinoma, seborrheic keratosis, etc.

There are two main types of dermoscopy: Non polarized and polarized dermoscopy.We’ve fitted most of our dermoscopys with polarized and non-polarized light. They canbe used in multiple skin structures.

Non-polarized contact Mode

In non-polarized mode, the instrument can provide information about the superficialskin structures, such as milia-like cysts, comedo-like openings, and pigment in theepidemis.

The dermoscopy requires applying a liquid such as mineral oil or alcohol to the skin andplacing the lens in contact with the skin. This reduces surface reflection and enhancesthe view of subsurface structures.

Polarized contact Mode

In polarized mode, the instrument allows for visualization for deeper skin structures,such as blood vessels, collagen, and pigment in the dermis.

The dermoscopy does not need to be in contact with the skin or use any liquid. Theirpolarized light can help to eliminate surface reflection and allow visualization ofvascular structures.

Polarized non-contact Mode

The dermoscopy can also use polarized light to examine the skin without direct contact.

In polarized non-contact mode, the instrument allows for examination infected areasand lesions that are painful for the patient, or the difficult to contact pigmented lesions,such as nails and narrow areas.

The contact plate should be removed in this mode, and it does not require applying aliquid to the skin. As it doesn’t require pressure or fluid application on the skin, it canalso avoid cross-contamination and infection risk.

Compared with visual inspection, the dermoscopy can be used to capture and store skin lesion photos, which play an important role in early skin cancer examination.

The dermoscopy allows the examination of skin lesions with magnification and illumination. This can be greatly avoiding the factors that cause interference to visual detection. Such as lighting, skin color, hair and cosmetics.

Several studies have demonstrated that dermoscopy is useful in the identification of melanoma, when used by a trained professional.

It may improve the accuracy of clinical diagnosis by up to 35%
It may reduce the number of harmless lesions that are removed
In primary care, it may increase the referral of more worrisome lesions and reduce the referral of more trivial ones

A 2018 Cochrane meta-analysis published the accuracy of dermoscopy in the detection.

Characteristics of the dermatoscopic structure of the skin lesions include:

• Symmetry or asymmetry
• Homogeny/uniformity (sameness) or heterogeny (structural differences across the lesion)
• Distribution of pigment: brown lines, dots, clods and structureless areas
• Skin surface keratin: small white cysts, crypts, fissures
• Vascular morphology and pattern: regular or irregular
• Border of the lesion: fading, sharply cut off or radial streaks
• Presence of ulceration

There are specific dermoscopic patterns that aid in the diagnosis of the following pigmented skin lesions:

• Melanoma
• Moles (benign melanocytic naevus)
• Freckles (lentigos)
• Atypical naevi
• Blue naevi
• Seborrhoeic keratosis
• Pigmented basal cell carcinoma
• Haemangioma
