Decreasing retinal photocoagulation damage: principles and techniques

Semin Ophthalmol. 1999 Dec;14(4):200-9. doi: 10.3109/08820539909069538.


Conventional suprathreshold retinal photocoagulation is a destructive procedure, but chorioretinal damage can be decreased by changing laser parameters and clinical endpoints. Laser effects can be localized by decreasing laser wavelength, spot size, and exposure duration, as well as by adopting threshold or subthreshold treatment protocols. Problems with short-pulse treatment regimens can be circumvented by the use of repetitively pulsed laser photocoagulators. Preliminary clinical results with reduced-damage photocoagulation methods are promising and await confirmation in larger, controlled clinical trials.
