7TH March marks the start of World Glaucoma Week. Glaucoma affects 78 million people around the world, and it is estimated that many more have the condition and do not realise it. This week is used to raise awareness about glaucoma and the importance of having regular eye examinations.

Glaucoma is a group of eye conditions that causes sight loss due to damage to the optic nerve. Often glaucoma has little to no symptoms and if left undetected can cause sight loss.

Open angle glaucoma is the most common type of glaucoma. This type of glaucoma often develops slowly with no symptoms and occurs when the eyes drainage channels become blocked. It is usually associated with older age or people of Afro-Caribbean heritage. Other types of glaucoma include closed angle glaucoma, secondary glaucoma and childhood glaucoma.

Glaucoma can be diagnosed following a routine eye examination, which is why it is incredibly important to keep up to date with them. At your eye examination our optometrists will use the OCT to take a 3D scan of the back of the eye. The images from the scan are available to view instantly and show your eyes in incredible detail allowing our optometrists to detect glaucoma and other eye conditions in their earliest stages. Early detection of glaucoma allows for treatment to begin as soon as possible and delay sight loss.

Glaucoma is treated by managing the underlying issues and preventing further damage to the optic nerve. There are two types of treatment for glaucoma; eye drops and laser surgery. Eye drops are used to reduce the amount of fluid being produced in the eye or improve fluid drainage. Laser treatment is commonly used to help reduce pressure in the eye.

Many regular eye examinations have been missed or delayed due to the pandemic. If you have noticed any changes to your vision or have missed an eye examination, please contact your local Bush Opticians today to book your appointment.
