    Reasons for Procedure

    This exam is done to look for retinopathy of prematurity (ROP). ROP is an abnormal growth of blood vessels in the retina. It is a rare conditions that that can occur in premature infants or those that have a low birth weight. ROP will usually go away on its own, but can sometimes cause vision loss or blindness. This exam will help determine if ROP is present and if treatment is needed.
    If your infant is at risk for ROP, this eye exam will be scheduled at regular intervals until the blood vessels of the eye are fully developed.

    Possible Complications

    Your infant may need eye drops during the exam. Your doctor will discuss the complications that may be caused by eye drops, such as:
    • Stinging or discomfort in the eye
    • Light sensitivity
    • Blurred vision
    • Lid swelling
    • Red eyes
    Be sure to discuss these risks with the doctor before the eye exam.

    What to Expect

    Prior to Procedure

    • Do not feed your infant right before the exam.
    • If recommended by the doctor, a pacifier during the exam may help soothe your infant.
    • The doctor will put eye drops in your infant’s eyes. These will make the pupils open wide. The drops will take about 30-60 minutes to work.


    Drops may be placed in the eyes to numb them and keep your infant comfortable.

    Description of the Procedure

    An assistant may gently place your infant in a blanket and hold him or her during the exam. A special device will be placed to keep your infant's eyelids open. A special lens will send a bright light into the eye so the doctor can see the blood vessels in the eye. The doctor may also use a tool to move the eye in different directions.

    How Long Will It Take?
