:
• Specific to retinal photocoagulation: inadvertent foveal burns; choroidal neovascularization;
paracentral scotomata; transient increased edema/decreased vision; subretinal fibrosis;
photocoagulation scar expansion; Bruch’s membrane rupture; choroidal detachment; exudative
retinal detachment; pupillary abnormalities from damage to the ciliary nerves; and, optic neuritis
from treatment directly or adjacent to the disc.
• Specific to laser iridotomy or iridoplasty: inadvertent corneal or lens burns/opacities; iritis; iris
atrophy; bleeding; visual symptoms; IOP spike; and, rarely, retinal detachment.
• Specific to laser trabeculoplasty: IOP spike, and, disruption of the corneal epithelium.
ENt:
Excessive treatment may cause swelling (edema) in the area treated by the laser.

One of the main concerns during otolaryngeal and bronchial procedures is the substantial risk of
endotracheal fires. The following sections provide information and safety guidelines, which can
greatly decrease the risks associated with these procedures. Information is also provided on what to
do if such a fire does occur.
IRIDEX Corp. recommends the safety guidelines of American National Standards ANSI Z136.3-2007
as follows:
• Care must be taken to protect endotracheal tubes from laser radiation. Ignition or perforation of
endotracheal tubes by the laser beam could result in serious or fatal patient complications.
• Use the lowest possible oxygen concentration to support the patient.
• Use the venturi ventilation technique when possible.
• Use intravenous anesthetic agents rather than inhalation techniques.
• Use non-flammable laser-safe endotracheal tubes.
• Protect the endotracheal tube cuff with wet cottonoids.
Reference material and additional information regarding laser safety and the prevention of
endotracheal fires may be obtained from the following U.S. sources:
