How is ROP treated?
The most effective proven treatments for ROP are laser therapy or cryotherapy. Laser therapy “burns away” the periphery of the retina, which has no normal blood vessels. With cryotherapy, physicians use an instrument that generates freezing temperatures to briefly touch spots on the surface of the eye that overlie the periphery of the retina. Both laser treatment and cryotherapy destroy the peripheral areas of the retina, slowing or reversing the abnormal growth of blood vessels. Unfortunately, the treatments also destroy some side vision. This is done to save the most important part of our sight the sharp, central vision we need for “straight ahead” activities such as reading, sewing, and driving. Both laser treatments and cryotherapy are performed only on infants with advanced ROP, particularly stage III with “plus disease.” Both treatments are considered invasive surgeries on the eye, and doctors don’t know the long-term side effects of each. In the later stages of ROP, other treatm
