How does fluid flow in the eye?

To understand how glaucoma develops, it helps to know how fluid circulates within the eye. Fluid is produced inside of the eye, just beneath the iris, by a structure known as the ciliary body. The fluid then travels through the pupil, and exits via the eye's drainage system, called the Trabecular meshwork. In healthy eyes, there is a normal balance between the fluid that is made in the eye and the fluid that leaves the eye. Therefore, this fluid creates a relatively constant and healthy pressure within the eye. This is called intraocular pressure, or IOP, and it maintains the eye’s shape and function while the fluid nourishes the eye. Sometimes too much fluid is created, or the fluid does not drain fast enough, which can lead to an increase in eye pressure. Increased intraocular pressure can damage the optic nerve and lead to vision loss. This is why your doctor monitors your eye pressure, and why it is important to have routine eye exams. While vision loss from glaucoma cannot be cured, treatments are available to address high IOP. When it comes to the health of your eyes, don’t delay. Speak with us to schedule your next eye exam.
