Note that it is not always possible to know immediately if your eye has been injured by a laser. Sometimes a flash in your eye will signal that you have looked into the laser. Sometimes the flash will not occur, or one may have bright flashes that occur as a part of the experiment. The first sign of damage may be a sandy or gritty feeling in the eye. It could be a dark spot or an "after image" (like those that occur after exposure to a flash bulb) that persists. Some symptoms may not occur for several hours after exposure. If you think you have sustained injury, observe the following procedures.

If at Stanford:

  • Bleeding in the eye is evidenced by a fogging or dark clouding of vision (sometimes reddish). Remain in a sitting position to prevent retinal bleeding from accumulating on the retina. Stay calm.
  • If possible, call for assistance from a colleague, seek medical advice; call the Stanford Eye Clinic, describe symptoms and injury. Follow their instructions.
  • Inform (or have colleague inform) the P.I.; and,
  • Call (or have colleague or P.I call) Health Physics at 723-3201.

If at home:

  • Rarely slight bleeding may not been noticed earlier or may be delayed. If symptoms of bleeding as described above occur, follow the instructions given above.
  • Call the Stanford eye clinic or the nearest hospital, describe the symptoms and injury. Follow their instructions.
  • Inform the P.I. as soon as possible after you have obtained medical attention. Request the P.I. to inform Health Physics at 723-3201.

For questions regarding the University Laser Safety Policy or the Administrative Panel on Radiological Safety, call Health Physics at 723-3201 or the Associate Dean of Research at 723-3763.

For advice on eyewear, posting (warning signs, laser labeling), the laser safety procedures, hazards control information, etc., call Health Physics at 723-3201. The e-mail account of the Health Physicist responsible for laser safety is arefehs@leland.stanford.edu.

For information on Chemical Safety, Compressed Gases and Cryogenic Safety and Electrical Safety, call Environmental Health & Safety at 723-0448.
