Questions

1. Which of the following best describes fluorescent light energy (FLE)? *

Low-level laser therapy utilizing monochromatic wavelengths of light in the visible to near-infrared range that stimulate tissue and impact cellular change.

Surgical laser utilizing invisible CO2-stimulated infrared wavelength emissions that are absorbed by water in skin and other soft tissue, vaporizing cells and thereby cutting tissue.

Photobiomodulation that utilizes a photoconverter hydrogel with chromophores activated by a blue LED to emit polychromatic wavelengths of light that provide nonthermal stimulatory effects at various depths of the skin, impacting cellular change.

Photodynamic therapy that combines light energy from a laser with a photosensitizer, releasing singlet oxygen molecules that destroy infectious organisms, cancerous and precancerous cells.

2. Which of the following FLE effects have been documented on skin? *

Antimicrobial activity

Reduction of inflammation

Improved wound healing

All of the above

3. Which of the following photoreceptors in the skin are stimulated by FLE? *

Flavins/riboflavin

Cytochrome c oxidase

Nicotinamide adenine dinucleotide hydrogen

All of the above

4. Which ONE of the following is a property of BLUE light emitted from FLE? *

Has a wavelength of 570–610nm

Penetrates to a depth of 6mm in the skin

Proinflammatory

Renders bacteria hypersusceptible to antimicrobial therapy

5. Which ONE of the following is a property of GREEN light emitted from FLE? *

Has a wavelength of 570–610nm

Penetrates to a depth of 6mm in the skin

Improves wound healing by targeting fibroblasts in the skin

Decreases fibroblast growth factor and transforming growth factor beta production in the skin

6. Which ONE of the following is a property of YELLOW/ORANGE light emitted from FLE? *

Has a wavelength of 570–610nm

Penetrates to a depth of 6mm in the skin

Decreases vascular endothelial growth factor production in the skin

Decreases angiogenesis

7. Which ONE of the following is a property of RED light emitted from FLE? *

Wavelength of 570–610nm

Penetrates to a depth of 6mm in the skin

Causes an imbalance in collagen production

Decreases angiogenesis

8. Which ONE of the following conditions is NOT an indication for treatment with FLE? *

Osteoarthritis

Superficial and deep pyoderma

Interdigital furunculosis

Perianal fistulas

9. Which ONE of the following is NOT consistent with FLE? *

Successfully reduces healing time with wounds and surgical incisions

Requires very precise positioning to ensure optimal beam delivery intensity and to target a small treatment area

Decreases or eliminates the need for systemic antibiotics

Should not be used in patients with porphyria, photosensitivity disorders or if taking medications known to induce photosensitivity reactions

10. Which ONE of the following is NOT consistent with FLE? *

Can either be performed twice weekly or via two applications back to back

Requires a high level of expertise and costly maintenance

Short two-minute sessions allow for better patient cooperation and acceptance

Is free from side effects and risks related to the use of traditional lasers
