Fields and pressures

Is there any value in carrying out tests 'just in case'?

When do you do fields and/or pressures on a patient? Would you do them on a 25 year old white patient with no symptoms or family history of relevant eye disease? I have often heard the argument that it ‘doesn’t do any harm’ to do these tests on a patient, even if they don’t need them. I am not convinced by this as although neither are invasive (assuming you do non-contact tonometry) there is always the risk that you may ‘find’ something that isn’t really there or is of no clinical significance.
