Photocoagulation Laser is a non invasive procedure, whereby a
strong in intensity and accuracy laser causes coagulating changes
on the tissues of the retina it reacts with.
The Laser application can be focal, grid pattern, or panretinal.

The molecules of Anti-VEGF combined
with those of VEGF deactivate them,
so that the new compound cannot
combine with the receptors and no
neovascularization occurs.
Focal Laser is performed on a small area of focal edema and on
microaneurisms that show leakage. Grid Laser treats more diffused
leakage. Both these procedures are used in non- proliferative
diabetic retinopathy.
