激光工作可造成眼的射线性损害已有大量证据。作者们专门研究了激光对胃肠道出血治疗时强烈回闪的危害。用两种特殊粘膜反射模型记录各种标准纤维内窥镜的回闪程度。氩和铵钆铝石榴石激光光源用来作为定值。研究证明,若附上滤光器, There is a good deal of evidence that radioactive damage to the eye can be caused by laser work. The authors specifically studied the dangers of laser flashback on the treatment of gastrointestinal bleeding. Two special mucosal reflectance models were used to record the flashback of various standard fiber endoscopes. Argon and ammonium gadolinium aluminum garnet laser light source is used as a fixed value. Studies have shown that if attached filter,
