Retinopathy of Prematurity
ROP happens when blood vessels in the retina do not develop as they should. It is not known why this happens in some infants.
Things that may raise the risk of this problem are:
- Premature birth , especially babies born before 28 weeks of pregnancy
- Low birth weight, especially babies weighing less than three pounds
- The use of supplemental oxygen, too much oxygen, or changing oxygen levels in the body
- Low levels of insulin-like growth factor (IGF-1) in the blood
- High blood glucose
- Poor nutritional status
There are usually no signs of ROP until it reaches a severe stage. Problems may be:
- White pupils
- Abnormal eye movements
- Eyes that cross and turn toward each other
Mild ROP will usually heal on its own. An eye doctor will watch for any changes during this time.
The goal of treating severe ROP is to lower the risk of the retina detaching and causing vision loss. Treatment options are:
- Cryosurgery—freezing tissue in the eye to prevent the spread of abnormal blood vessels
- Laser ablation/photocoagulation—using a laser to stop abnormal blood vessels from growing
