It is well known that patients with multiple sclerosis note fluctuations in their symptoms under certain circumstances. For instance, it is generally known among patients that they feel more uncomfortable in heat than in cold. Heat aggravates partly their general condition and partly their neurological symptoms. In addition to an exacerbation of the existing symptoms, heat may even induce new ones, such as the transient visual impairment after a hot bath. This phenomenon has also been observed during muscular exertion and after eating.

Before proceeding to general considerations regarding these visual complaints and their relation to stress, we shall briefly report this patient's history.
