Treatments for Retinopathy of Prematurity
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.
Later stages of ROP treatment options
Scleral Buckle
This involves placing a silicone band around the eye
and tightening it. This keeps the vitreous gel from pulling on the scar
tissue and allows the retina to flatten back down onto the wall of the
eye. Infants who have had a sclera buckle need to have the band removed
months or years later, since the eye continues to grow; otherwise they
will become nearsighted. Sclera buckles are usually performed on
infants with stage IV or V.
Vitrectomy
Vitrectomy involves removing the vitreous and replacing it
with a saline solution. After the vitreous has been removed, the scar
tissue on the retina can be peeled back or cut away, allowing the
retina to relax and lay back down against the eye wall. Vitrectomy is
performed only at stage V. for ROP
