title: Ophthalmic hazards associated with laser endoscopy.
abstract: It is well documented that work with lasers poses a risk of ocular radiation damage. We specifically investigated the risk of intense backflash during laser treatment of gastrointestinal bleeding. Two well-characterized models of mucosal reflections are used to document flashback levels on several standard fiberoptic endoscopes. Both argon and neodymium-YAG laser sources are evaluated. Filter attachments that will provide adequate protection from the flashback hazard are also described.
