Vision Screening Online Training Program
Module 4 (continued): Binocular Fix and Follow/Extra Ocular Movement (EOM)
(C&TC: Often performed by the health care provider)
The binocular fix and follow test is a great test to see if a child's eyes work together and are symmetric in their ability to follow an object. It is important to keep the child's head staring straight ahead for this test so that it is only the child's eyes that move to follow the object. This will give the screener the best vantage point to observe any deviation in the child's eye movements.
|Ages:||4 months to when visual acuity can be measured.|
|Description:||The child's head is stabilized while a target is moved in horizontal, vertical and oblique patterns in relation to a center point on a visual axis. The target is also moved from the center point toward the child.|
|Equipment:||Penlight or interesting target.|
|Pass:||Both eyes follow the target easily and smoothly.
Occasional Crossing: Normal at 2 months of age. Recheck at 4 month visit.
Fixed Crossing: Refer
|Re-screen/Refer:||Eyes do not follow in unison or movements are jerky, uneven, or "break" further than 4 inches from the bridge of the nose, or child uses head movements.|
