A parent recently asked me whether shoulder dystocia can affect a child's vision.
The short answer is: sometimes, but it's uncommon. The good news is that the vast majority of shoulder dystocia deliveries are resolved without permanent vision problems.
However, in some of the more severe shoulder dystocia cases I've handled, vision-related complications have been part of the child's overall injury.
Two conditions that have come up are Horner syndrome and Cerebral Visual Impairment (CVI).
Horner syndrome can occur in infants with severe brachial plexus injuries and may cause a drooping eyelid, a smaller pupil on one side, or facial asymmetry.
CVI is different. A child's eyes may appear structurally normal, but an injury to the brain can affect how visual information is processed. Parents may notice difficulties with eye contact, visual tracking, or responding consistently to objects and faces.
Importantly, CVI is not caused by shoulder dystocia itself. Rather, it may occur when a severe shoulder dystocia results in a significant oxygen-deprivation injury to the brain.
These conditions are rare and are generally associated with more significant birth injuries. Most shoulder dystocia deliveries are resolved safely without lasting harm.
I recently wrote an article explaining what Horner syndrome and CVI are, how they can be connected to severe shoulder dystocia cases, and some of the signs families may want to discuss with their child's medical team.
If your child experienced a shoulder dystocia and you've been told they have Horner syndrome, CVI, or another vision-related diagnosis, you're not alone. These conversations can be overwhelming, and getting accurate information matters.

The good news is that most children who experience shoulder dystocia will never develop vision problems. However, in some severe birth injury cases, vision-related complications can occur.
