Intraocular carbon dioxide laser photocautery. I. Animal experimentation
J. B. Miller, M. R. Smith, F. Pincus and M. Stockert
Intraocular carbon dioxide laser photocautery is used to produce localized
closure of vascular channels and chorioretinal adhesion in the albino
rabbit. The retinal lesion is sharply demarcated because of the high tissue
absorption of CO2 laser radiation. Varying degrees of chorioretinal
adhesion can be achieved. The CO2 laser photocautery technique may provide
a suitable method of closing vessels and sealing retinal tears at the time
of vitrectomy. Accurate placement of the cautery tip on the target area can
be accomplished under stereoscopic magnified viewing with the operating
microscope and contact lens. Electrical shock hazard is completely
eliminated with the CO2 laser energy modality.
