How to interview a patient with sudden vision loss
Other platforms explain it with text and video. In VMS you practice it on the patient.
Sudden vision loss is an emergency. The history points to the eye, the blood supply or the brain.
Step by step
Introduce yourself and act fast
Check visual acuity early; call for help if stroke signs are present. [1]
One eye or both
Cover each eye: loss in one eye points to the eye or its blood supply; half the field in both eyes points to the brain. [2]
Onset
Seconds, minutes, hours; curtain coming down; came back or not. [2]
Pain and redness
Painful red eye with halos suggests acute glaucoma. [1]
Flashes and floaters
Suggest retinal detachment. [1]
Stroke and arteritis symptoms
Weakness, speech problems, headache, jaw pain when chewing, scalp tenderness in older adults. [1]
Summarize and act
Arrange urgent eye or stroke care. [3]
Common errors
- Waiting when vision came back (it may be a warning stroke).
- Not testing each eye.
- Missing giant cell arteritis.
Practice it in VMS
In VMS you do this on the patient, not on paper: every step goes on the checklist with a score, and in Teach mode Blocky tells you what comes next.
