Glaucoma Referral Refinement & OHT Monitoring

LOCSU has developed  care pathways for glaucoma referral refinement, OHT monitoring and ocular hypertension diagnosis.

The aim of the pathways is to reduce unnecessary referrals to the hospital eye service; reduce patient anxiety and increase capacity within the overburdened hospital glaucoma clinics. This will privide a more cost effective service with a greater number of patients being managed within the primary care setting. This has been shown in the North East of Scotland and in Manchester, where there has been a reduction in false positive referrals of 40%.

The referral refinement pathway would allow accredited optometrists to repeat diagnostic tests to confirm the risk of disease, and thus improve the accuracy of referrals and deflect unnecessary referrals. The service would also allow diagnosis of ocular hypertension (OHT) and suspect chronic open angle glaucoma (COAG) by accredited optometrists, retaining more patients in primary care.

The aim of an OHT and suspect COAG monitoring pathway is to reduce the number of secondary care consultations for the cohort of patients who are diagnosed either as having OHT i.e. consistently high intra-ocular pressures (IOPs) but no glaucoma, or as being COAG suspect i.e. normal IOP but other suspicious signs. Currently, patients considered to have a greater chance of developing COAG due to elevated IOP or other suspicious signs are generally retained in secondary care and reviewed there on an annual basis, following referral in. The new service would provide for these patients to be discharged back into primary care for monitoring by community optometrists. Patients would only be referred back into secondary care if there was a change in clinical status.

Updated Glaucoma/OHT pathways  and    powerpoint presentation following publication of NICE Glaucoma Guidelines

LOCSU has updated its glaucoma/OHT package of support, following  the publication of the NICE  guidelines on glaucoma ensuring that there is no contradiction between the requirements of NICE and the  pathways themselves. Please click here  or on the pdf document to the right of your screen for a copy of the pathway.

LOCSU has also updated its powerpoint presentation, complete with briefing notes, which can be used to explain the glaucoma care pathway to commissioners and to open up discussions on developing an enhanced glaucoma service in your area. Please contact LOCSU  to discuss how we can help you to develop a business case    and to work    towards getting    the pathway commissioned in your area.    

NICE Glaucoma Referral Guidelines  

The NICE guidelines, published in April 2009,    provide a framework for the diagnosis and management of chronic open angle glaucoma (COAG) and ocular hypertension (OHT) in England and Wales. The guidelines require that OHT should ber formally diagnosed using gonioscopy before continued monitoring; OHT is defined in the guidance as intraocular pressure over 21 mm Hg.

The AOP, ABDO and FODO strongly advise optometrists to take note of the NICE Guidelines when considering the referral of patients with signs of OHT.   To access  the joint advice  from these bodies, please click here
