I've got high blood pressure. Will this affect my eyes?
When optometrists talk about pressure within the eye (intra-ocular pressure), they mean pressure of the fluid which fills the eye, rather than pressure of blood in the vessels which keep the structures of the eye supplied with oxygen and nutrients. High intra-ocular pressure is associated with the development of some eye conditions, such as glaucoma.
High blood pressure is not directly linked to high pressure of the fluid in the eye and therefore is not directly associated with eye conditions such as glaucoma, however, poorly controlled high blood pressure can cause other problems related to damage to the delicate blood vessels at the back of the eye.
