Reasons for Procedure    TOP

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.

Be sure to discuss these risks with the doctor before the eye exam.
