A stroke affecting the eyes often causes sudden, painless changes in vision. These signs should never be ignored.
Typical warning symptoms
When blood flow to the retina or optic nerve is blocked, vision may reduce quickly. The problem may involve one eye or affect part of the visual field.
- Sudden dark patch, curtain, or complete loss of sight in one eye
- Brief episodes of vision loss that then recover transient ischaemic attacks
- New double vision or difficulty focusing straight ahead
- Often no eye pain, making symptoms easy to overlook
Why urgent action is vital
Eye strokes are medical emergencies and can signal risk of a brain stroke. Fast treatment offers the best chance of preserving sight and preventing further events.
- Call emergency services immediately for sudden vision loss
- Note the exact time symptoms began, if possible
- Long-term care focuses on managing blood pressure, cholesterol, and lifestyle
- Regular follow-up with eye and medical teams will be needed
