Open Angle Glaucoma

Open-angle glaucoma is the most common type of glaucoma. Primary Open Angle Glaucoma (POAG) affects about 2% of people in the UK older than 40 years (NICE,2017).

What is Open Angle Glaucoma?

This is the most common type of glaucoma. Patients often have no symptoms but the eye pressure is often found to be raised during a routine eye test.


Primary Open Angle Glaucoma (POAG) has no identifiable cause.
Secondary Open Angle Glaucoma can be caused by certain eye conditions (eg pseudoexfoliation, pigment dispersion syndrome, uveitis, trauma, steroid response) can cause secondary glaucoma.

Risk factors for POAG include :

Family history of glaucoma

Age (more common with age)

Race (African, Asian or Caribbean origin more common)

Gender (more common in men)

Systemic disease (eg diabetes, hypertension)


The symptoms of open closure glaucoma depend on the cause and severity of the increase of intraocular pressure:

Most people with primary open angle closure have no symptoms.

Increasing pressure can damage the optic nerve, initially affecting peripheral vision. Driving may become more difficult, only noticing hazards when they are in the centre of the field of vision.

The lack of obvious symptoms highlights the importance of regular eye checks, by optician or ophthalmologist, to detect increased intraocular pressure, reduced field of vision and narrow drainage angles.


Elevated intraocular pressures can be controlled by:

Eye Drops

Either a single drop or a combination of drops


Selective Laser Trabeculoplasty (SLT)


Cataract surgery alone, Minimally Invasive Glaucoma Surgery (MIGS), Trabeculectomy, Filtration (Tube) Surgery

So helpful and reassuring. My site is amazing. The whole process was so smooth, I understood everything that I was told and knew of any risks and potential side effects before agreeing to anything. Couldn't be happier.

I recently had permanent lens procedure carried out by Mr Ghosh. Having glasses as a child and contact lenses for many years, this has been an absolute revelation for me. Mr Ghosh was absolutely brilliant and very professional from the start. All the staff are lovely and especially like to thank Dianne, Anita and the team. This has changed my life for the better thanks.

I visited the My Hearing Clinic knowing I needed a hearing assessment but thinking it was just a build up of wax. It came as a shock that I heard a hearing loss which needed addressing. The service I received from Andrew was outstanding! He explained my hearing loss and went through all my options. He recognised that it was a lot of information to take in so made a follow up appointment, giving me sufficient time to think about what I wanted to do. From start to finish the service has been excellent, efficient, professional and friendly from the moment you walk through the door and meet Lee. The clinic is well located, parking on site, high standard of cleanliness. Definitely a recommendation from me. Thank you!
