[Experimental retinal vascular photocoagulation with the argon laser. Optic microscopic study of the results in...

Argon laser vascular retinal photocoagulation's experimental study on rabbit point out hemorrage risk when using 1500 mw, 0,05 sec, 200 microns beam. If 800 mw 0,05 sec, 200 microns beam is selected white cell migration comes at 48 hours inside and outside the photcoagulated vessel. On human one can success intermaculopapillar photocoagulations without injurying intern retinal layers (we use 300 mw, 0,05 sec, 200 microns beam). At 650 mw, 0,05 sec, 200 microns perivascular retinal injury is considerable, but at 24th hour on artery there is no evidence of obliteration possibility.
