Introduction to SubLiminal Laser Therapy

> SubLiminal laser therapy

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

SubLiminal® 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.

The Role of the New Generation of Lasers in Retina
Through the years, laser has evolved dramatically. Although intravitreal injections have become the first line of treatment of macular pathologies such as diabetic macular edema (DME), laser application within clinical settings continues to prove efficacious in macular conditions.

How new generation lasers are different from each other
Laser has changed a lot over the years, the newer laser can deliver energy in different ways, by reducing the duration to 10-20 ms, in a train of pulses of 0.1 ms as in the micropulse / subliminal laser, and extremely short duration of 0.0017 ms as in the nanosecond laser. Clinical studies have shown that micro­pulse laser is efficacious in multiple macular conditions
