The mnemonic

PBACH

What each word stands for

  • PProstaglandin analogues increase uveoscleral outflow
  • BBeta-blockers decrease aqueous production
  • AAlpha-2 agonists decrease production and increase outflow
  • CCarbonic anhydrase inhibitors decrease production
  • HHyperosmotics (mannitol) for acute lowering

Why it matters clinically

Quick drug-choice recall, including contraindications such as beta-blockers in asthma.

Where it stops being reliable
