The short explanation
Yes, she should be seen urgently today, even though her vision has come back. A brief, sudden loss of vision in one eye that recovers within minutes can be a warning sign of reduced blood flow to the eye, sometimes caused by a small clot. It can be a warning of stroke, similar to a mini-stroke, and needs prompt checking. Doctors will check her eyes, blood pressure, heart rhythm, blood sugar and cholesterol, and may arrange scans of the blood vessels in the neck. Finding and treating the cause quickly can reduce the risk of a stroke or permanent vision loss.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- High blood pressure, diabetes, high cholesterol, smoking and heart rhythm problems increase the risk.
- Weakness, numbness, slurred speech or face drooping alongside vision loss are signs of stroke.
- Headache with jaw pain on chewing and scalp tenderness in older adults can suggest inflammation of blood vessels, which also needs urgent care.
- Government hospitals can assess her in the emergency department.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what caused her vision loss. She needs urgent examination and tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What caused her vision loss?
