Raeder's syndrome is defined as a part of Homer's syndrome, in which only the 3rd sympathetic nerve is damaged. The 3rd nerve arises from the superior cervical ganglion and goes to the eyes. Raeder's syndrome lacks the anhidrosis of the face and the heterochromia iridis present in Homer's syndrome.We have examined two patients with Raeder's syndrome, a 62-year-old female with malignant lymphoma and a left cervical mass, and a 40-year-old male with a Schwannoma of the left side of the neck. Two cases of squamous cell carcinoma with marked cervical metastasis in the terminal stage and similar symptoms of Raeder's syndrome are also discussed.The most reliable method of differentiating the two syndromes is the pupillary drug test with sympathomimetic drugs. We used 1% phenylephrine. In Raeder's syndrome, marked dilatation of the pupils and improvement of ptosis were noticed.When we see Homer's syndrome patients with a cervical mass, this test should be used to better locate the tumor.
