Types of Ocular Migraines
Ocular migraines, also known as retinal migraines, can be classified into two main types: migraines with an aura and retinal migraines. Migraines with an aura can cause various visual disturbances such as blind spots, patterns, and flashes of light. These symptoms can impair the victim’s vision and also affect the central nervous system, resulting in difficulties with motor skills and speech. On the other hand, retinal migraines typically occur in one eye and are usually more severe in terms of visual impairment. Individuals experiencing this type of ocular migraine often report complete loss of vision or the perception of twinkling lights.
Triggers of Ocular Migraines
Ocular migraines are still not fully understood by scientists, making it challenging to pinpoint their exact causes. However, research suggests that certain triggers may contribute to the occurrence of ocular migraines. Some of these triggers overlap with those associated with epilepsy, such as exposure to flashing lights and electronic screens. Additionally, factors like fluorescent lighting, prolonged visual attention required during long-distance traveling, and other similar events may also act as triggers for ocular migraines. Moreover, it has been observed that ocular migraines are more likely to occur in individuals who are experiencing stress, dehydration, low blood sugar levels, or excessive heat.
