• Argon endophotocoagulation may not be possible in some eyes due to the poor view afforded by the operating microscope. This limitation is avoided by viewing through argon filter goggles with the indirect ophthalmoscope while applying treatment with the endophotocoagulation argon laser probe through a pars plana entry site. This method has proved particularly helpful in the gas-filled eye, for treatment over a preexisting scleral buckle, or for a more complete peripheral panretinal photocoagulation.
