Treatment for ROP is based upon disease severity, as defined by the International Classification for Retinopathy of Prematurity (ICROP) (figure 1). Treatment is initiated when the infant develops type I ROP (also called "high-risk prethreshold ROP").
Full Answer
What is the treatment for retinopathy of prematurity?
Treatment of retinopathy of prematurity. Early diagnosis of damage is important in the treatment of ROP. Babies who develop severe ROP may benefit from a treatment called cryotherapy that uses freezing to stop further damage from occurring. Another treatment uses laser photocoagulation to create small burns and scar tissue.

Stage 0 is the mildest form of ROP while Stage 5 is the most severe indicating total retinal detachment. Doctors may also use the terms “popcorn” referring to a scarring that is regressing following abnormal vessel growth. The term, “hot dog”, may refer to a red hot ridge of increasing abnormal vessel grow.
What are the stages of retinopathy of prematurity?
The first stage of ROP is a demarcation line that separates normal from premature retina. Stage 2 is a ridge which has height and width. Stage 3 is the growth of fragile new abnormal blood vessels [See figures 2 and 3]. As ROP progresses the blood vessels may engorge and become tortuous (plus disease).
What is Stage 2 Zone 3 ROP?
Zone 2 is the intermediate (between the posterior and peripheral) retina. Zone 3 involves the peripheral (or outer) retina. The retinal vessels begin to develop in zone 1 and then gradually grow outward to the retinal periphery until reaching zone 3; thus, zone 1 involvement is more severe than zone 3 involvement.

What happens if a baby is born prematurely?
If the baby is born prematurely, there can be a problem with this growth. In some premature babies, the blood vessels grow into parts of the eye where they do not belong. This can cause scar tissue to form inside the eye. The scar tissue can damage the retina and cause a significant loss of vision. This condition is called retinopathy ...
How to reduce tension in the eye?
One way to reduce the tension on the retina is to push the wall of the eyeball inward. This can be done using something that looks like a rubber band. This elastic band is placed around the eyeball, and it pushes the inside surface of the eye up against the retina. This is called scleral buckling.
How does scar tissue damage the retina?
The abnormal blood vessels and scar tissue damage the retina by pulling it away from the inside surface of the eyeball. This is called a retinal detachment, and it can cause a significant loss of vision. One way to reduce the tension on the retina is to push the wall of the eyeball inward.
What is the procedure to remove vitreous fluid?
This material is called the vitreous fluid, and the procedure to remove it is called a vitrectomy. In addition to removing the vitreous fluid, the surgeon will also remove the scar tissue that is pulling on the retina. This should help reduce the chances of a retinal detachment and prevent the loss of vision.
