Do arteries pulsate in the eye?
Visible retinal artery pulsation arises from a pathological state (as opposed to SVP which is physiologic) in which IOP greater than diastolic retinal arterial pressure causes partial or complete collapse of the vessel during part of the cardiac cycle.
Are venous pulsations in eye normal?
The pulsations are observed as a subtle narrowing and expansion of one or more retinal veins on the optic disc and are present in 90% of normal persons. The examination technique requires adequate visualisation and magnification.
Are spontaneous venous pulsations normal?
These findings confirm that the presence of spontaneous venous pulsations is a reliable indicator of an intracranial pressure below 180 to 190 mm H2O, while the absence of pulsations may be found with normal intracranial pressure and is therefore not a reliable guide to raised intracranial pressure.
What is ocular hypertension?
Ocular hypertension is when the pressure inside the eye (intraocular pressure or IOP) is higher than normal. With ocular hypertension, the front of the eye does not drain fluid properly. This causes eye pressure to build up. Higher than normal eye pressure can cause glaucoma.
Can an eye stroke be fatal?

Without blood flow, the cells in the retina don’t get enough oxygen. They can start to die within minutes or hours. An eye stroke is an emergency.
What are pulsations?

What is a Papilloedema?
Papilledema is a condition in which increased pressure in or around the brain (intracranial pressure) causes swelling of the part of the optic nerve inside the eye (optic disc). Symptoms of increased intracranial pressure include headache or nausea and vomiting.
Can you have ocular hypertension without glaucoma?
Not all people with ocular hypertension will develop glaucoma. However, people with ocular hypertension have an increased risk of glaucoma. Therefore, if you have ocular hypertension, it is essential to have regular comprehensive eye examinations.
How do you know if you have ocular hypertension?

What is Pseudopapilledema?
Disease. Pseudopapilledema is defined as anomalous elevation of one or both optic discs without edema of the retinal nerve fiber layer. Papilledema, on the other hand, is a swelling of the optic disc due to increased intracranial pressure.
What does ocular hypertension feel like?
Pain generally feels like a stabbing, burning, or stinging sensation. Pressure behind the eyes feels like fullness or a stretching sensation inside the eye.
