Acute Glaucoma

Red, hard, aching eye, hazy cornea and blurred vision

  • Where to refer:
    • Eye Casualty


Primary open angle glaucoma

  • Information to include
    • Optometry referral must indicate disc and/or field defect compatible with glaucoma, or angle at risk of closure. Patients with family history are screened by optometrist
  • How to refer
    • Routine with copy of optometrist referral with info on refraction, IOP, disc and field enclosed if abnormal.
    • Book fields
    • Urgent if IOP >32mmHg
    • If re-referral, refer to current consultant
    • If transfer from another hospital eye service unit include last hospital eye service letter


Ocular hypertension

If IOP >/= 32mmHg + symptoms of acute glaucoma = immediate referral to EYE CASUALTY

If IOP >/= 32mmHg and no symptoms of acute glaucoma do URGENT O/P referral.

If IOP >/= 24mmHg but < 32mmHg do ROUTINE O/P referral.  

How to refer

  • Patient referred on GAT form
  • Copy of optometrist letter with detail of refraction and optic disc, GAT, IOP and visual field result.

Note: Non contact tonometry tends to over read. All Optometrists should now be measuring IOP with Goldman applanation tonometry (GAT) prior to referral.
