Clinical description and review of migraine aura without headache

Background:
Migraine aura without headache (MAWOH) is a type of migraine that seems to be reported more frequently in ophthalmic than neurologic or general medical practice. The clinical characteristics of this condition are described relative to its relationship with other forms of migraine, patient age, gender distribution, laterality, personal or family history, visual aura, and precipitating factors. As a result of its prevalence, it is a condition with which every optometrist and ophthalmologist should be familiar. Since MAWOH is a common cause of photopsia and transient vision loss, it is also important to consider it in the differential diagnosis of these conditions-especially in older patients.
Methods:
The clinical investigations of MAWOH by prospective and retrospective case series are reviewed. This review includes an analysis by study of the number of patients, migraine history, and type of visual symptom. Comparison of clinical characteristics is used to distinguish MAWOH from other types of migraine.
Conclusion:
Migraine aura without headache is a type of migraine that is reported frequently in ophthalmic practice. Because it is related to photopsia and/or transient vision loss, specific clinical procedures should be performed to assist in the differential diagnosis of these conditions.

Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
