Quick answer

Stroke can suddenly affect vision in one or both eyes, cause double vision, or remove part of the visual field. Sudden vision loss with weakness, numbness or speech problems is a medical emergency — call emergency services immediately. After a stroke, eye specialists and low-vision teams can help with recovery and daily living.

## How stroke affects the eyes

Stroke damages brain areas that process vision or control eye muscles. You may lose one side of your visual field, see double because the eyes no longer align, or lose vision in one eye from a retinal artery blockage linked to vascular disease. Brief one-eye vision loss (amaurosis fugax) can precede stroke even when sight returns — treat as an emergency.

## Amaurosis fugax and eye stroke

Amaurosis fugax is temporary vision loss in one eye, often described as a curtain passing across sight for seconds to minutes. It warns of emboli from carotid artery disease or heart rhythm problems. Retinal artery occlusion is the eye-stroke event when vision does not return. Both need emergency stroke and eye assessment the same day.

## Emergency warning signs

Think FAST and include eye symptoms:

- Face drooping on one side
- Arm weakness or numbness
- Speech slurred or hard to understand
- Time to call emergency services — sudden vision loss or double vision counts too

## After acute treatment

Some visual problems improve in the first weeks; others persist. Prisms in glasses, patching for double vision, scanning training for field loss, and low-vision aids can help. Occupational therapists and stroke teams support return to reading, driving assessment and safe mobility.

## Ongoing eye care

Stroke survivors still need routine eye checks for glaucoma, cataracts and other common conditions. Tell your optometrist about your stroke history and any new vision change.

## Frequently asked questions

### What is amaurosis fugax?

It is sudden temporary vision loss in one eye, often like a curtain. It can warn of stroke or retinal artery blockage and needs emergency assessment even if vision returns.

### Can a stroke cause blindness?

Stroke can cause significant visual field loss or double vision. Complete blindness in both eyes from stroke alone is less common but any sudden major vision loss is an emergency.

### Will vision return after stroke?

Some improvement is possible, especially early on. Rehabilitation and low-vision support help people adapt when recovery is incomplete.

### Can I drive after stroke-related vision loss?

Driving rules depend on visual field and double vision standards where you live. A formal assessment is required — do not drive until cleared.

Your next step

## Take this to your appointment

Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
