Lasers pose a significant threat to vision in modern military operations. Anti-personnel
lasers have been designed that can cause intentional
blindness in large numbers of personnel. Although the use of blinding
laser weapons during combat has been prohibited by international legislation, research and development of these weapons have not been prohibited, and significant controversy remains. Unintentional blinding can also result from other types of
lasers used on the battlefield, such as range-finders and anti-material
lasers.
Lasers that are capable of producing
blindness operate within specific wavelength parameters and include visible and near infrared
lasers. Patients who suffer from
laser eye injuries usually complain of flash
blindness, followed by transient or permanent visual loss.
Laser retinal damage should be suspected in any patient with visual complaints in an operational setting. The treatment for
laser retinal injuries is extremely limited, and prevention is essential. Improved protective eyeware and other countermeasures to
laser eye injury are necessary as long as the threat remains.
