What is Glaucoma?

“A blinding condition which can be prevented with the latest safe and modern treatments.”

Mr Vik Sharma


Glaucoma is a serious eye condition that occurs due to damage to the optic nerve. Glaucoma causes the affected person to experience vision problems, which progressively worsen over time.

Glaucoma can, worryingly, go undetected until your eyes have suffered permanent damage.

Unfortunately, at present, there is no cure available to treat glaucoma. However, with early diagnosis and timely treatment, you will be able to prevent your eyesight from worsening and retain your sight. For this reason, regular eye checks with a qualified ophthalmologist are vital.

At Harley Street Eye Hospital, our facilities and surgeons deliver the top glaucoma surgery there is. We have vast experience working with glaucoma patients, and we can provide the customised treatment you require.

Glaucoma is usually caused by increased pressure in your eye which then compresses the optic nerve. Although, it should be noted that some types of glaucoma can present with no increased pressure in the eye, which can make them tricky to diagnose.

Who is most vulnerable to glaucoma?

Typically, the following individuals are vulnerable to glaucoma:

  • People with poor vision or other eye conditions
  • People over the age of 40
  • People with thin and sensitive corneas
  • People with diabetes, high blood pressure or anaemia
  • People with a genetic vulnerability to glaucoma
  • People who have experienced eye injury

What are the symptoms of glaucoma?

  • Headaches
  • Red eyes
  • Tunnel vision
  • Dizziness
  • Blurry vision
  • Halo-rings in the line of sight
  • A vision that progressively worsens – initially in the peripheral vision, later centrally
  • Pain on and around the eye
  • Nausea and vomiting

Treating glaucoma

At Harley Street Eye Hospital, our team of consultants will use a combination of medicine, laser treatment, and surgical procedures to help you keep your eyesight. Our treatments are highly-personalised, and your medical requirements and needs are taken into consideration. Our surgeons are trained in delivering the best glaucoma surgery in the United Kingdom.

Eye Drops

Some less severe cases eye drops can be used to lower the eye pressure. Whilst eye drops can be great as they are not invasive, they are also not a permanent solution to glaucoma treatment.

Laser treatment

Laser treatment has become increasingly popular and is also a non-invasive procedure. Although, laser surgery is not a permanent solution, and needs to be repeated after a couple of years.

XEN Implant
