Lasers have been a useful piece of technology, from the operating room to the laboratory. However, according to www.medicalnewstoday.com, a new study conducted by Schepens Eye Research Institute discovered that a laser burn injury in one eye will likely affect both eyes.

Reproductive, brain, and eye tissues all posses what is known as immune privilege. Immune privilege, according to medicalnewstoday.com, “is a modification of the body’s normal immune response.” Normally, the body’s immune system will use inflammation to attack foreign invaders; however, inflammation is harmful to the delicate tissues of the reproductive system, brain, and eyes. Without immune privilege, eyes are susceptible to the body’s inflammation, which can further damage them.

Using mice, the study found that after receiving even small laser burns in one retina, “immune privilege was disrupted in both eyes after six hours and continued to be disrupted even after 56 days.” This knowledge will be helpful in treatments for individuals suffering from laser burns resulting from military action or other instances in which lasers are commonly used. “Understanding mechanisms that destroy or disrupt immune privilege will ultimately lead to novel therapies to restore that special privilege not only in the eye but in the brain and the reproductive system as well,” says medicalnewstoday.com.
