Horner's Syndrome is a syndrome which involves damage to the sympathetic system controlling one of the eyes. Signs of Horner's syndrome may include constricted pupil, elevation of the third eyelid, retraction of the eyeball into the head, slight drooping of the eyelid, and an increased pink color and warmth of the nose and ear on the affected side.
Damage to the sympathetic system may occur in the eye area, ear area or neck area from trauma, abnormal blood clot, middle ear infection, tumor, or disease of the eye. Special eye drops may be used to help diagnose Horner's syndrome and determine whether the first or second nerve segment is involved. Most cases of Horner's syndrome involve the second nerve segment. Chest radiographs may also be used to rule out the possibility of cancer.
Horner's syndrome is not painful and does not interfere with vision. Often times, treatment is not necessary, particularly in cases involving the second nerve segment, and the syndrome is allowed to clear up on its own. This typically occurs within six to eight weeks. Other action may be required in cases involving the first nerve segment if there are problems in the chest or spinal cord. Phenylephrine eye drops can be prescribed for cosmetic purposes. |
