Q-4. Tobey Ayer Test is positive in
a) Lateral sinus thrombosis
b) Petrositis
c) Cerebral abscess
d) Subarachnoid hemorrhage
Answer: Lateral sinus thrombosis
Explanation:
Tobey-Ayer-Test is used in the diagnosis of lateral sinus thrombophlebitis. This is to record CSF pressure by manometer and to see the effect of manual compression of one or both jugular veins.
In cases where the lateral sinus is obstructed on one side, compression of the jugular vein on the intact side causes a rise in CSF pressure, whereas compression of the obstructed side does not raise the CSF pressure.
