What causes terson syndrome?

What causes terson syndrome?

Terson’s syndrome refers to the occurrence of vitreous hemorrhage with subarachnoid hemorrhage (SAH), usually due to a ruptured cerebral aneurysm. Although it is a well-described entity in the ophthalmological literature, it has been only rarely commented upon in the neurosurgical discussion of SAH.

How is terson syndrome treated?

Terson’s Syndrome is managed conservatively by observation for mild cases and with vitrectomy for bilateral cases and for patients whose hemorrhage has not spontaneously resolved after an observational period.

What is Preretinal hemorrhage?

Preretinal hemorrhage is a known complication of diabetic retinopathy. 1 Typically patients present with painless loss of vision due to the blood accumulation in the premacular area between the retina and posterior hyaloid face, or under the internal limiting membrane.

Is vitreous hemorrhage reversible?

The outlook (prognosis) in vitreous haemorrhage depends both on the cause and on the severity. Vitreous haemorrhage resulting from posterior vitreous detachment usually has a good prognosis, with restoration of vision, particularly if the eye is otherwise normal.

What is Tersons syndrome?

Terson syndrome is now recognized as intraocular hemorrhage associated with SAH, intracerebral hemorrhage, or traumatic brain injury. Hemorrhage may be present in the vitreous, sub-hyaloid, subretinal space, or beneath the internal limiting membrane.

What is PVD eye?

In posterior vitreous detachment (PVD), the gel that fills the eyeball separates from the retina. It’s a common condition with age. PVD can cause floaters or flashes of light, which often fade over time. PVD isn’t painful or sight-threatening.

What does a retinal hemorrhage look like?

Seeing haze or shadows. Distorted vision. Rapid flashes of light in peripheral vision. Red tint to vision.

Can stress cause vitreous hemorrhage?

Stress is not a recognized cause of subconjunctival hemorrhage. The good news is, if you had a conjunctival hemorrhage, these are only cosmetically annoying but go away and do not endanger the vision.

What does vitreous hemorrhage look like?

Vitreous hemorrhage has variable symptoms depending on the amount of bleeding: vision of spots that are suspended in vision (floaters), blurred vision or complete and sudden loss of vision. It may be caused by multiple causes, such as eye traumas and even underlying conditions such as diabetic retinopathy.

What is a sentinel headache?

Introduction. Sentinel headache before a subarachnoid haemorrhage (SAH) is well described as a sudden, intense, persistent headache, with features different from any usual previous headache. It precedes subarachnoid haemorrhage by days or weeks and occurs in 15–60% of patients with spontaneous SAH [1].
