CHECK YOUR UNDERSTANDING
High intracranial pressure
(inside the skull) typically is a
result of an injury to the head
and can be very dangerous.
A screening test for high
intracranial pressure was
proposed many years ago,
based on the data in the
following observations. This
simple and non-invasive test
involves observing the retinal
vein to see if it is pulsating.
Pulsation is normal and so would be considered a negative test result.
Pulsation Absent
(Positive Test)
Pulsation Present

(Negative Test)
High Intracranial Pressure
(Condition Present)

Normal Intracranial Pressure
