How does laser radiation affect the retina?
For lasers emitting wavelengths in the “retinal hazard spectral region,” approximately 400 to 1,400 nm, damage is characteristically confined to the retina. In such cases, radiation is transmitted through the cornea, aqueous humor, lens and vitreous humor and is imaged or focused to a small area on the retina. The severity of the injury is dependent on the exposure dose. In contrast, shorter ultraviolet laser radiation and longer infrared laser radiation are both absorbed by the cornea. And in some of the transitional spectral regions, the lens and the iris are at risk, said Mr. Stuck.
What are the effects of laser eye surgery?
Factors that affect the extent of laser eye injury include: 1 Pupil size 2 RPE and choroidal pigmentation 3 Poor retinal or choroidal circulation 4 Presence of cataract 5 Power and density of laser 6 Duration, dose and distance from source of exposure 7 Use of protective eyewear 8 Enhancement by reflective media, such as mirrored surfaces

In 1995, Mr. Stuck was involved in an international conventional weapons conference that resulted in the “Protocol on Blinding Laser Weapons.” Under this protocol, to which the United States is a signatory, four articles delineate the parameters for the use of lasers in military maneuvers and war.

What are lasers used for?
Lasers are ubiquitous in military applications, serving in targeting and guidance systems, fire-control devices, access-denial systems and communications security. Although the use of lasers as a weapon is a violation of the Geneva Convention, the potential for nefarious use continues to attract international concern. “In military applications, just a few microjoules of laser through the pupils in a 10 to 30 nanosecond pulse can produce a visible lesion. At 150 to 300 microjoules, a small retinal hemorrhage can occur,” said Mr. Stuck. This type of damage can have a devastating effect on a pilot’s vision.

Can you have bilateral or unilateral eye injuries?
Because a person may focus each eye independently when intersecting a collimated light bundle, injuries can be either bilateral or unilateral. “It all depends on how the person interacts with the source,” said Dr. Hacker. “Sometimes people are taught, if they work in dark environments, to keep one eye closed, intentionally keeping it dark-adapted. In these cases, only one eye is exposed. Similarly, just because a person incurs a bilateral injury, it does not always mean that the injuries are equal. Some people have stronger vision in their left or right eye. It also depends on how they are oriented when exposed. Even a couple of fractions of a degree in fixation seem to make a difference. Exposure duration also plays a critical role.”
