Horner syndrome, (also known as Horner’s syndrome, Horner-Bernard syndrome or oculosympathetic palsy) results from the disruption of a nerve pathway between the brain, face, and eye on one side of the body. The most common causes of Horner syndrome in infants includes injury to the neck or shoulders during delivery.
Horner syndrome results in a drooping upper eyelid, decreased pupil size, and decreased sweating on one side of the face. Other symptoms include a noticeable difference in pupil size between both eyes, little or delayed opening of the affected pupil in dim light, drooping of the upper eyelid, elevation of the lower eyelid, and sunken appearance to the eye. Additionally, little or no sweating on the entire affected side of the face or part of the affected side of the face may occur. If Horner syndrome occurs from a birth injury, the colored part of the eyes, known as the iris, of the affected eye may be lighter in color than that of the unaffected eye. In some children, it may be difficult to detect the upper eyelid drooping and decreased sweating.
Three groups of nerve cells (neurons) may be affected by neck trauma at birth to cause Horner syndrome. First, the neuron pathway that leads from the hypothalamus at the base of the brain through the brainstem and extends into the upper portion of the spinal cord may be injured. Second, Horner syndrome can be caused by an injury to the neuron pathway extending from the spinal column across the upper part of the chest and into the side of the neck. Third, the neuron pathway extending along the side of the neck and up to the facial skin and muscles of the iris and eyelids may be injured.
