Anisocoria
Anisocoria refers to unequal pupil size. This can be a normal finding, but can also
represent a life-threatening condition such as some causes of Horner’s syndrome
and brain aneurysms. The most reassuring thing about unequal pupil size is the
time that it has been present for, which can be sometimes seen in old photos. You
need to see a specialist though to determine whether you need to get an MRI of
your brain done or any further testing.
