[Effects of laser chorioretinal photocoagulation]

Laser-chorioretinal interactions depend on: non controllable parameters: spectral transmission, absorption of tissue, scattering of laser, distribution of ocular chromophores, thermal conductivity of tissue. They are important determinant of laser tissue effects. parameters that can be monitored by the physician: size of the spot, pulse duration, laser energy and laser wavelengths. Theoretical predictions of laser-tissue interaction with the choroid and the retinal agree with histological and clinical data. The choice of physical parameters of laser must be done in order to prevent adverse effects as to obtain researched therapeutic goal.
