I also run a weekly discussion Forum at our church, and he is a popular guest speaker. At his talk last year he mentioned that doctors are moving beyond hard-and-fast pressure numbers and thresholds, with the recognition that glaucoma is actually a question of pressure balance (ocular vs. blood). He has seen blood pressure reduction medications start to trigger glaucoma symptoms, particularly in patients with high normal intraocular pressure.
