[Mechanisms of laser photocoagulation in diabetic retinopathy].

The aim of laser photocoagulation in diabetic retinopathy is to stop the development of retinal neovessels and even to determine their involution. Early applied, laser photocoagulation can significantly reduce the risk of severe visual loss. The knowledge of the multiple mechanisms of laser photocoagulation leads to the possibility to introduce a well dosed treatment that is appropriate for the clinical stage of the retinopathy.
