Ocular Migraines
The classic migraine
is a severe headache, which in some instances may be accompanied
by nausea. Ocular migraines are visual disturbances in which
visual images look gray or have a wavy appearance. They almost
always occur in only one eye. Other common symptoms are loss
of vision, particularly in one eye, and increased sensitivity
to bright lights. The visual distortion, when it occurs, normally
starts in central vision and then moves off to one side.
The ocular migraine can occur either in conjunction with the
common migraine or without the corresponding headache. Generally,
when it accompanies the common migraine, the visual disturbances
happen before the onset of headache symptoms. In younger people
with common migraine, it is typical for the ocular migraines
to also occur. As people age, it becomes more common to experience
ocular migraines without headache symptoms.
In general there is no serious complications caused by ocular
migraine. Treatment, in most instances, is not necessary unless
the ocular migraine is linked to the common migraine.
