SCINTILLATING SCOTOMAS Meaning and
Definition
-
Scintillating Scotomas refers to a visual phenomenon characterized by the presence of shimmering, flickering, or flashing lights in one's field of vision. It is often described as a zigzag or wavy pattern that occupies a small portion of the visual field and gradually expands over a span of 20-30 minutes before fading away. This visual disturbance is typically associated with a temporary loss of vision in the affected area.
Scintillating Scotomas are commonly experienced by individuals who suffer from migraine headaches, particularly those with a history of migraine with aura. The scotomas often occur as a prodromal symptom or warning sign, alerting individuals to an impending migraine attack. They may be accompanied by other sensory disturbances such as tingling sensations, numbness, or speech difficulties.
The precise physiological mechanisms underlying Scintillating Scotomas are not fully understood. However, it is believed that they result from cortical spreading depression, a temporary disruption of normal neuronal activity in the brain. This phenomenon may affect the visual processing centers, leading to the perception of abnormal light patterns.
Although Scintillating Scotomas can be disorienting and cause temporary visual impairment, they are generally harmless and resolve spontaneously. However, individuals experiencing this visual phenomenon should exercise caution when engaging in activities that require clear vision, such as driving or operating machinery.
In summary, Scintillating Scotomas refer to the perception of shimmering or flashing lights in the visual field, often associated with migraine headaches. They are temporary and self-resolving visual disturbances that typically occur prior to a migraine attack.
