BRAIN

CRANIAL NERVES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Increased CSF pressure obstructing the return of venous blood from the retina by pressing the central vein of the retina. This condition is known as:
A
optic neuritis
B
hemianopia
C
papilloedema
D
None of the above
Explanation: 

Detailed explanation-1: -Papilledema refers to optic disc swelling secondary to elevated intracranial pressure (ICP) [1]. Optic disc edema occurs as a result of reduced perfusion to retinal ganglion axons and subsequent swelling of the axons with leakage of cellular contents into the extracellular space of the optic disc [2, 3].

Detailed explanation-2: -Papilledema occurs when there is increased pressure on the optic nerve from the brain and CSF. This pressure causes the nerve to swell as it enters the eyeball at the optic disc. There are some serious medical conditions that can cause this increased pressure to develop, including : head trauma.

Detailed explanation-3: -Patients presenting with papilledema from IIH with asymmetric IOPs display better visual function in the eye with higher IOP. This observation suggests that IOP may be a factor in the pathophysiology of visual loss from IIH.
