Paralysis of the oculomotor nerve with alternating phases of spasm and relaxation that always involve the sphincter muscle of the pupil and frequently involve some of the other paralyzed muscles (usually called in the ophthalmic literature cyclic oculomotor nerve paralysis) is of infrequent occurrence. Therefore, it may be of value to report two cases and to summarize the relatively small amount of literature on the subject. If one is permitted to pass judgment on the extent of the knowledge of this characteristically typical syndrome on the basis of the titles and contents of the articles which have been published, one must conclude that the disease is not well known. We have been able to find reports of only thirty-five cases since the first description in 1884 by Rampoldi, and wish to report two additional typical cases.
The table gives the most important data regarding the reported cases. A summary of
