Glaucoma is a disease of the optic nerve, which is the part of the eye that carries the images we see from the eye to the brain. The optic nerve is made up of many nerve fibers (like an electric cable containing numerous wires). Glaucoma damages nerve fibers, which can cause blind spots in our vision. Typically, these blind spots initially involve the peripheral, or side, vision. This loss can occur slowly enough that symptoms are not noticed until the disease is far advanced.
The development of glaucoma is frequently associated with an elevated pressure inside the eye, or intraocular pressure (IOP). When the clear liquid called the aqueous humor–which normally flows in and out of the eye–cannot drain properly, pressure builds up in the eye. The resulting increase in IOP can damage the optic nerve.
The most common form of glaucoma is primary open-angle glaucoma, where the aqueous fluid that normally circulates in the front portion of the eye is blocked from flowing back out of the eye through its tiny drainage system. This causes the pressure inside your eye to increase, which can damage the optic nerve and lead to vision loss. Most people who develop primary open-angle glaucoma notice no symptoms until their vision is impaired.
In angle-closure glaucoma, the iris (the colored part of the eye) may completely close off the drainage angle, abruptly blocking the outflow of aqueous fluid and leading to increased IOP or optic nerve damage. In acute angle-closure glaucoma, there is a sudden increase in IOP due to the buildup of aqueous fluid. This condition is considered an emergency because optic nerve damage and vision loss can occur within hours of the problem. Symptoms can include nausea, vomiting, seeing haloes around light, and eye pain.
Even people with “normal” IOP can experience vision loss from glaucoma. This condition is called normal tension glaucoma. In this type of glaucoma, the optic nerve is damaged even though the IOP is considered normal. Normal tension glaucoma is not well understood, but we do know that lowering IOP has been shown to slow progression of this form of glaucoma.
Childhood glaucoma is rare and starts in infancy, childhood or adolescence. Like primary open-angle glaucoma, there are few, if any, symptoms in the early stage. Blindness can result if it is left untreated. Like most types of glaucoma, this type of glaucoma may run in families.
We may tell you that you are at risk for glaucoma if you have one or more risk factors, including elevated IOP, a family history of glaucoma, a particular ethnic background, advanced age, or certain optic nerve conditions. Regular examinations are important if you are at risk for this condition.

My first eye exam at Boulder Eye Surgeons was very thorough and informative. The technician that gave the eye exam was very friendly and explained exactly what was going on behind these blue peepers regarding my far sightedness! Dr. Keller is my favorite eye doctor and I would recommend him for any serious eye difficulty.
I wouldn’t trust my eyes to anyone other than Boulder Eye Surgeons. THE BEST!!!
Short wait to be seen. Everyone makes you feel comfortable. Working with Chris was great. Dr. Cuevas explains things in easy to understand terms and is never condescending. He makes you feel secure in his knowledge. Dr. Cuevas is my go-to guy for eye problems.
Boulder Eye Surgeons have made it easy to visit safely during the COVID-19 pandemic. My appointment was on-time and efficiently executed. This is an outstanding ophthalmology office.
Always professional - always 'top notch'. Dr. Keller and the staff are always respectful and kind. I feel that Dr. Keller is an excellent eye surgeon that I can trust.
Pre and post cataract surgery followup with BES staff was excellent. All staff members were very knowledgeable and efficient as I called several times with questions. Surgery with Dr. Cuevas was excellent and I am very happy so far with results. Dr. Cuevas was clear and transparent with answers to my post-surgery questions and spent substantial time with me pre-surgery to make sure we came up with the best solution to meet my athletic vision requirements. I highly recommend Boulder Eye Surgeons.
The professionalism of the entire staff is impressive. Dr. Nichols spent adequate time with me explaining everything thoroughly. My daughter came with me and he took the time to address her concerns and answer her questions. The Optical department is just as 5 star as the rest of the practice. I am so grateful to these people for how they are addressing my problems with my eyes which involve a complex medical condition.
