Pathology of Monkey Retina Following Irradiation With an Argon Laser

Closure of Experimental Subretinal Neovascular Vessels With Dihematoporphyrin Ether Augmented Argon Green Laser Photocoagulation

“…Argon laser photocoagulation retinal lesions and toxicity have been studied extensively by L'Esperance el al. (1969), Rosan et al (1969) and Campbell et al (1969); the photocoagulation parameters to be used in this study are dependent on this information. A Coherent 900 argon blue-green laser set on green only, at 514 nm, was used.…”

Clinical aspects of ophthalmic argon laser

“…The blood vessel will, in many cases, undergo vasoconstriction with concomitant decreased blood flow, followed by vasodilation with resumption of regular blood flow, followed by thrombus formation [57]. However, Rosan et a1 [43] believe that retinal vessels can be blocked using argon laser photocoagulation techniques, but the mechanism is an indirect one and is due to the heat generated from the laser beam's reaction with the subjacent retinal pigment epithelium [49]. the thermal reaction produced by the absorption of laser light by the melanin granules within the retinal pigment epithelium.…”

“…The effects of the argon laser on the acid mucopolysaccharide material [60], which consists of half-sulfated chondroitin Once endothelial damage has occurred, circulating platelets may adhere to the inThis second, or indirect, mechanism for retinal vessel photocoagulation is based on sulfate and sialoglycans coating the outer segments of photoreceptor cells in the subretinal space, has not been elucidated as yet [43].…”

“…The scar, with its adhesion, can be used to tack neurosensory retina to the pigment epithelium in patients with retinal breaks but without a retinal detachment. It has been stated that the adhesion produced by the ruby laser or the xenon arc photocoagulator is stronger than that produced by the argon laser [43]. The explanation for this is not clear and must be due to factors other than thermal reaction alone.…”
