Glaucoma: diagnosis and management NICE guideline (NG81 November 2017, updated January 2022)

As advised by secondary care

  • Where a prostaglandin analogue is indicated for reducing intraocular pressure (IOP), Latanoprost is first line. Patients currently using other forms of prostaglandin analogues may be reviewed when seen routinely by secondary care.
  • Offer another pharmacological treatment to people with an IOP of 24 mmHg or more who cannot tolerate their current treatment. The first choice should be an alternative generic prostaglandin analogue (PGA), and if this is not tolerated, offer a beta-blocker. If neither of these options is tolerated, offer a non-generic PGA, carbonic anhydrase inhibitor, sympathomimetic, miotic or a combination of treatments.
