What is SubLiminalTM Laser Therapy?

Introduction to Yellow 577nm SubLiminalTM Laser Therapy

Sascha Fauser, MD

Subthreshold TV

In contrast to conventional laser photocoagulation, SubLiminalTM laser therapy does not use a continuous-wave laser beam leading to a thermal effect.

 

SubLiminalTM laser therapy is based on a stimulation concept, using extremely short microsecond laser pulses followed by cooling time periods.

As a result, by using short enough laser pulses (Time on) and long enough cooling times (Time off) the targeted tissue can cool between laser pulses, preventing retinal damages.

Since the SubLiminalTM technology inception, various treatment protocols based on different laser technologies have been suggested.

 

Following to clinical researches, Professor Victor Chong initiated the creation of SubLiminalTM treatment guidelines based on the use of the new technologies available with modern lasers (such as Yellow 577nm wavelength and the multispot delivery of SubLiminalTM laser).

 

These guidelines facilitate the SubLiminalTM laser therapy implementation and ensure a safe treatment of DME and CSCR.

SubLiminalTM Laser Therapy for Central Serous Chorioretinopathy

Sascha Fauser, MD

Central serous chorioretinopathy (CSCR) is one of the most common retinal causes of vision loss(1).

 

It is characterized by serous detachment of the neurosensory retina secondary to one or more focal lesions of the retinal pigment epithelium (RPE)(1).

This pathology ranks among the most common vision-threatening retinopathies after AMD, diabetic retinopathy and branch retinal vein occlusion(3).

 

In acute CSCR, the detachment is caused by a focal leak in the RPE. It usually resolves spontaneously within a few weeks(2). However, chronic CSCR can lead to permanent structural damage and often pronounced loss of central vision (5 - 7).

 

Different treatment options are available, but there is no "gold standard" treatment for chronic CSCR(4):

 

                    • Traditional thermal photocoagulation can be used for extrafoveal leakages, but it is destructive and can lead to symptomatic scotomas and
                       choroidal neovascularization.

 

                    • PDT laser therapy can also be used, however, even when using reduced treatment settings; it has also number of side effects such as RPE
                       atrophy, choroidal neovascularization, choriocapillaris ischemia, and transient reduction of macular function.

 

                    • Yellow 577nm SubLiminalTM laser therapy seems to be a promising alternative treatment strategy(4).

Yellow 577nm SubLiminalTM Laser Therapy for Diabetic Macular Edema

Victor Chong, MD

Subthreshold TV

Diabetic retinopathy is the leading cause of visual loss and blindness in working age populations in the developed world. Diabetic macular edema (DME) is the leading cause of blindness in the diabetic population.

 

A recent pooled analysis from 35 population-based studies estimated that 93 million people worldwide have diabetic retinopathy, of whom 17 million (~18%) have proliferative DR, 21 million (~23%) have diabetic macular edema (DME), and 28 million (~20%) have sight-threatening DR(1).

 

The treatment of DME has changed significantly in the past years.

Nevertheless the best treatment option applicable to all DME patients still remains an open question.

Although the introduction of anti-VEGF therapies has shown its safety and efficacy, the laser still plays an important role(2)(3).

 

Yellow 577nm SubLiminalTM laser therapy can be an excellent adjunct or alternative to anti-VEGF therapies.
