Could heavy straining like heavy sneezing coughing and vomiting etc cause blood vessels in the iris to burst/break? If so what are the symptoms?

In brief: No

We don't see blood vessels in the iris break in these scenarios, however it is very common to get subconjunctival hemorrhages where a blood vessel on the white of your eye breaks, causing an appearance of a red eye.
