Recent developments in laser treatment of diabetic retinopathy.

Laser photocoagulation has been the mainstay of diabetic retinopathy treatment since its development in mid-20(th) century. With the advent of antivascular endothelial growth factor therapy, the role of laser therapy appeared to be diminished, however many advances in laser technology have been developed since. This review will describe recent advances in laser treatment of diabetic retinopathy including pattern scan laser, short-pulse duration and a reduced fluence laser, and navigated laser system for proliferative diabetic retinopathy and macular edema.
