This guideline covers diagnosing and managing glaucoma in people aged 18 and over. It aims to address uncertainty and variation in clinical practice by giving clear recommendations on testing for chronic open angle glaucoma and ocular hypertension and on effective diagnosis, treatment and monitoring to stop these conditions progressing. This has the potential to prevent more people from going blind.


This guideline includes recommendations on:

Who is it for?

  • Healthcare professionals
  • Adults with chronic open angle glaucoma or ocular hypertension, or who are at high risk of developing glaucoma, their carers and families

Is this guideline up to date?

We checked this guideline in November 2015 and we are updating the recommendations on monitoring and treating chronic open angle glaucoma, ocular hypertension and suspected chronic open angle glaucoma. See the guideline in development page for progress on the update.

Next review: July 2017

Guideline development process

How we develop NICE guidelines

This guideline was previously called glaucoma: diagnosis and management of chronic open angle glaucoma and ocular hypertension

Your responsibility

The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals and practitioners are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or the people using their service. It is not mandatory to apply the recommendations, and the guideline does not override the responsibility to make decisions appropriate to the circumstances of the individual, in consultation with them and their families and carers or guardian.

Local commissioners and providers of healthcare have a responsibility to enable the guideline to be applied when individual professionals and people using services wish to use it. They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Nothing in this guideline should be interpreted in a way that would be inconsistent with complying with those duties.

Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
