A member asked:
What is the cause of butterflies in your vision when you cuff?
A doctor has provided 1 answer
Butterflies: The visual phenomenon of butterflies in your vision due to coughing is due to the transient increase in abdominal pressure and resultant effects on blood flow to the brain/eyes. It is nothing to worry about.
