Photodynamic Therapy
Photodynamic therapy is considered a minimally invasive procedure, performed in an outpatient setting, consisting of an intravenous administration of a photosensitizing drug (Verterporfin) with its subsequent activation by laser radiation with defined wavelength – Diode laser (Non-thermal), with a wavelength of 690 nm.
It has the great advantage of effectively accumulating the administered product in the anomalous structures (neo-vessels) given its high propensity for a type of receptors of a particular form of Plasma Lipoproteins (LDL) present in large numbers in the neo-vascular structures that are rapidly proliferating.
When activated by the laser, this drug results in the formation of highly reactive intermediary chemical forms that trigger a mechanism of destruction of the abnormal neo-vascular structures, without affecting the healthy cells and retinal structures.
After each treatment, it is advisable for the patient to remain in semi-darkness, avoiding direct exposure to light, and should only leave the house after 48 hours of treatment.
