What are the Symptoms?
Some of Horner’s syndrome symptoms, based on information from the Mayo Clinic, will typically affect only one side of the face. Let’s say that your child had a lesion. Horner’s syndrome will impact the area surrounding the eye.
There a few signs that give away this condition. A child may only display two or three of Horner’s syndrome symptoms, but they could still have it. For example, one of the most obvious signs is that they have a drooping eyelid. This normally happens due to damage of the Muller’s muscle. You may also see a persistently constricted pupil. This has become known as miosis. Another one of the symptoms is that the eye might appear sunken in. Also, when you look into your child’s eyes, you might notice that their pupil dilates slowly and repeatedly in dim light.
