Migraine Associated with Water Deprivation and Progressive Myopia

Migraine is one of the most common types of headache encountered in clinical practice. It can be precipitated by many factors, e.g. stress, hunger, extreme temperature, etc. Migraine has a lot of variants, including retinal migraine that leads to transient reversible monocular blindness. However, present classification of headaches is based on phenomenology (1), which leads to the appearance of variants of headache in the literature. Recently, Blau et al. (2) attracted the attention of the medical community towards an old but less known form—water deprivation headache. However, the existence and importance of these variants is still in question. We present a case of migraine that not only was precipitated with water deprivation, but also responded to water ingestion. Simultaneously, this case also showed ‘exacerbation of myopia’ on the affected side after each episode.
