Effects of argon and krypton laser on experimentally detached retinas.
Krypton and argon laser photocoagulation on the foveas and blood vessels of experimentally detached monkey retinas were studied clinicopathologically. In this manner heat transmission from the retinal pigment epithelium (RPE) to the overlying sensory retina was avoided. Krypton lesions bypassed the sensory retina on every occasion to produce major photocoagulative effects at the level of the RPE and choroid. Argon laser wavelengths damaged the overlying retina in the foveal areas as well as in perivascular structures. Although the krypton laser appears preferable for treatment of macular diseases, proper parameters should be used to avoid serious complications.
