Glaucoma

Glaucoma is a range of diseases that damage the optic nerve. Age, blood pressure, family history, diabetes, ethnicity and short or long-sightedness can all contribute to your risk of glaucoma. https://glaucoma.uk/about-glaucoma/what-is-glaucoma/

Glaucoma is often relatively symptomless to start with and as symptoms generally develop slowly, damage can occur without you being aware. Most people are recommended to have an eye test at least every two years unless they’ve been advised otherwise by a doctor.
