Can a TIA cause visual disturbance?
One of the first signs of a Transient Ischaemic Attack (TIA) or stroke can be visual disturbance – loss of vision in one area of the visual field which can be experienced as not being able to see on one side. Another problem can be seeing double.
Can a TIA cause blurred vision?
The symptoms in the FAST test identify most strokes and TIAs, but a TIA can occasionally cause different symptoms that typically appear suddenly (usually over a few seconds).

How does a TIA affect your eyes?
TIA in the eye Occasionally a TIA happens that only affects your eye. This happens when a blood vessel leading directly to one of your eyes becomes blocked and causes a temporary loss of vision in that eye. This is sometimes called amaurosis fugax or transient monocular blindness.
Which symptoms can be present with a transient ischemic attack?

- Weakness, numbness or paralysis in the face, arm or leg, typically on one side of the body.

What causes sudden loss of vision in one eye?
Common causes of sudden vision loss include eye trauma, blockage of blood flow to or from the retina (retinal artery occlusion or retinal vein occlusion), and pulling of the retina away from its usual position at the back of the eye (retinal detachment).
