About Glaucoma

In most cases of Glaucoma, abnormally high intraocular pressure is the cause of the damage. It is important to maintain annual visits with your eye doctor because most people with glaucoma have no early symptoms or pain from intraocular pressure. The pressure could be caused by poor circulation in eye fluid in the front part of the eye. The eye fluid (called aqueous humor) flows through a mesh-like channel, but when the channel gets blocked, fluid builds up and causes glaucoma. The cause of the blockage is unknown, but doctors have identified that glaucoma is hereditary.

The two main types of glaucoma are open-angle glaucoma and angle-closure glaucoma. The most common type is open-angle glaucoma. In this case the eye structure appears normal, but aqueous humor does not flow correctly through the drain of the eye, the trabecular meshwork. Angle-closure glaucoma is less common, but causes a sudden buildup of pressure in the eye. In this case the drainage channel between the iris and the cornea is too narrow.

What our Patients Say

‍A few years ago, I decided to have laser eye surgery to correct my lifelong problem with nearsightedness.  Before that I always wore glasses or contacts.  I remember having frequent problems with contacts which would lead to problems with sunglasses or diving masks and the like.  when I chose to have eye surgery, I decided to go with Dr. Narvaez.  As a surgeon myself, I knew of his reputation and we had some patients in common and I was always impressed by his work.  Therefore, the choice was clear to me even though I knew many other Doctors who could do the procedure. After the procedure, I had excellent vision.  I love my new vision and enjoy being glasses and contacts free.  Dr. Narvaez is an excellent surgeon and I highly recommend him.

What our Patients Say

I endorse my ophthalmologist, Julio Narvaez, MD.I have known him since moving to Loma Linda University in 2010.I was referred to him by a trusted friend and Ophthalmologist and was his patient; he is caring, bright and understood the problem and how I needed to be treated. He explained my options and allowed me to feel I had chosen my treatment while gently steering me the right direction. He was flexible when I asked to have my choice of anesthesia, which was local without sedation. He was not bothered by my continuous alertness during the surgery.

He is a bright and flexible surgeon, who makes excellent personal decisions and keeps perspective in his work and life.I would happily return to him for more care when needed.I endorse him without reservation and am glad to consider him a friend and colleague. Sincerely,

Dean A Hadley, MD Loma Linda University

What our Patients Say

It’s amazing to have new technology nowadays. Previously, I had worn eyeglasses for over 35 years. After having Symfony lenses implanted into both eyes, it’s a wonderful feeling to be able to read almost everything without glasses. All the worries and fears prior to the surgery were for nothing. It’s awesome; my vision is clearer and better!  I’m so grateful to have a very good, knowledgeable, and hardworking team. My experiences with you will forever be in my heart. God is so good. He will always guide me all the way.
