In the case of proliferative diabetic retinopathy (new vessels),
panretinal photocoagulation is performed, that covers the whole
retina except for the area of themacula. The purpose of this treatment
is not to improve vision rather than to maintain the existing level of
vision.
Applying Laser is not a surgical procedure and can be performed
on an outpatient basis. If performed in a specialized unit, by an
experienced doctor, any possible complications are practically
nullified.
Athens Eye Hospital
has at its disposal the ultramodern PASCAL
system (PAttern SCAnning Laser) by Optimedica, that can apply
simultaneously 10 (ten) laser shots, while the conventional laser
applies only one at a time. This reduces dramatically the treatment
time [especially for panretinal photocoagulation (PRP) that requires
up to 2000 shots] and ensures a uniform amount of energy and
great accuracy in the final result.
In the attempt to reduce collateral thermal damage caused by
conventional laser, especially the retinal pigment epithelium (the
membrane that nourishes the retina), a new technology has recently
evolved, called Micropulse Laser.
The main difference with the conventional laser is that the energy
produced is not continuous, but short small energy pulses that gives
the retina in between time to cool. As a result Micropulse therapy
can be repeated according to the patients’ needs, without causing
any damage. It can also be used in conjunction with Anti-VEGF
treatment in an attempt to reduce edema better and faster.
