Although the ASA or APSF find no evidence to support IOP screening, in procedures known to be associated with ischemic optic neuropathy...

I proceed regardless of risk factors and tell the patient that PION can occur but rarely happens.
I ask about risk factors for PION (glaucoma, HTN, DM, vascular disease) and check IOP if they have risk factors.
I have the patient's IOP checked every case preoperatively.
I make no special preoperative assessments or discussions.
