Why Yellow 577nm?

The 577nm true yellow wavelength is not actually a new addition to the therapeutic armamentarium in ophthalmology. It was introduced 20 years ago for the treatment of diabetic retinopathy. At that time, it was a favored wavelength among retinal specialists.

 

Unavailable during an entire decade for technological reasons, it has been reintroduced in ophthalmology a couple of years ago with the improved efficiency and the reliability of the solid state technology.

Theoretically, the 577-nm yellow laser light provides peak absorption of oxyhemoglobin, excellent lesion visibility, low intraocular light scattering and pain, and negligible xanthophyll absorption(1)(2).

 

In the literature, the yellow 577nm wavelength has been described as a safe and versatile wavelength:

 

           • Thanks to its absorption characteristics, it causes lesser scatter and requires the use

              of a lower energy level compared to green (532nm) and other yellow (561 to 568nm)

              wavelengths(5)

 

           • It is minimally absorbed by macular xanthophylls(1)(3), potentially allowing for treatments

              close to the fovea(5)

 

           • It is highly absorbed by the oxyhemoglobin (absorption peak) and thus optimal for the

              treatment of vascular lesions and subretinal vascular proliferations(4)

 

           • It allows an excellent penetration through cataracts(6)

Victor Chong, MD, explains the place of laser and anti-VEGF injection in proliferative diabetic retinopathy and diabetic macular edema treatments:

 

          • PRP is useful, especially in patients with

            PDR

          • Laser is still useful for early DME

          • A combination therapy of PRP and an

            anti-VEGF agent may be useful in

            treatment-naïve patients with DME
