Glaucoma Enhanced Referral Refinement Service (GERRS)
Community-based monitoring for borderline glaucoma suspects — closer to home, without the hospital outpatient wait.
Glaucoma monitoring, closer to home
Community Glaucoma Monitoring — No Hospital Needed
If a routine eye test raises concerns about glaucoma, the traditional pathway leads to a long hospital outpatient queue — for what may turn out to be a false alarm. GERRS changes that.
Our GERRS-accredited optometrists can monitor borderline suspects in practice, using the same clinical tests as a hospital outpatient clinic. Only patients who genuinely need hospital care are referred — everyone else is managed efficiently and closer to home.

The GERRS pathway
What Happens at Your GERRS Appointment
A comprehensive clinical assessment equivalent to a hospital glaucoma outpatient appointment — conducted by our accredited optometrists in Wythenshawe.
You must be referred by an optometrist following a routine eye test where suspected glaucoma has been identified — for example, raised eye pressure, borderline optic nerve appearance, or visual field defects.
Automated visual field perimetry maps your peripheral vision and identifies any areas of loss consistent with glaucoma.
Eye pressure is measured accurately using calibrated tonometry equipment. Multiple readings may be taken at different times of day if indicated.
Digital photographs of the optic nerve head are taken. Your optometrist examines the disc for signs of glaucomatous damage and compares results over time.
A full clinical report is produced. If the findings indicate stable borderline status, monitoring continues. If progression or definitive glaucoma is found, a hospital referral is made with your full clinical record.

Frequently Asked Questions
GERRS — Glaucoma Enhanced Referral Refinement Service — is a community-based scheme that allows accredited optometrists to monitor patients who have been referred for suspected glaucoma. Rather than waiting in a hospital outpatient queue, suitable patients can be monitored in a primary care setting, with referral to hospital only if the condition progresses or becomes definitive.
GERRS is for patients who have been referred from routine eye tests for suspected glaucoma — for example, borderline optic nerve appearance, raised intraocular pressure, or visual field defects — but where the diagnosis is not yet confirmed. It avoids unnecessary hospital outpatient appointments for patients who may not have glaucoma at all.
GERRS is commissioned by NHS in areas where it is available. Please contact us to confirm current availability and funding in your area. We will advise you on the options and costs before any appointment.
If your monitoring results indicate definitive glaucoma or significant progression, we refer you directly to the hospital eye service with a full clinical report. You will not be left to manage this alone — we provide a clear, prioritised referral.
