Delayed Gratification: Your Superpower to Success

A simulation of cloudy vision caused by glaucoma


Are you experiencing blurred peripheral vision, eye pain, or other symptoms of vision loss?

You may have glaucoma, and early treatment is vital to prevent blindness.  The truth is, many patients don't have any symptoms at all.

The doctors at Arizona Eye Institute use the most advanced technology to accurately diagnose and treat glaucoma patients in Phoenix, AZ. 

What Is Glaucoma?


Glaucoma refers to a group of eye diseases that cause intraocular pressure to build up inside your eye, putting stress on the optic nerve. There are several kinds of glaucoma, open-angle glaucoma being the most common. All types of glaucoma, if not treated, can cause blindness.

Symptoms of Glaucoma

Early action is key to preventing vision loss from glaucoma. Gradual vision loss is often the most common sign of glaucoma, but other symptoms can indicate glaucoma as well. If you notice any of these irregular vision symptoms, request an appointment at one of our greater Phoenix, AZ, offices right away. 

  • Vision Loss 
  • Halos Around Lights
  • Blind Spots
  • Severe Headaches
  • Nausea
  • Eye Pain
  • Red Eyes
  • Haziness of the Cornea

If You Have Glaucoma Your Vision May Look Like This

Tree and field
Patients with glaucoma may notice haziness in their peripheral vision. If you experience this symptom, reach out to Arizona Eye Institute in Phoenix immediately for a comprehensive eye exam. Opthalmologist Emilio Justo can diagnose and treat both open-angle and angle-closure glaucoma.

Se Habla Español We Welcome Spanish-Speaking Patients

It can be hard to find quality eye care if there is a language barrier between you and your doctor. At our Greater Phoenix, AZ, offices, we want to give you extra peace of mind when communicating about your health and treatment options. Dr. Justo speaks Spanish and is happy to converse with you in the language you're most comfortable with.

What's the Cause
of Glaucoma?


Glaucoma is caused by a buildup of a clear liquid called aqueous humor at the back of the eye. Normally, the liquid would filter out of the eye through a drainage channel, but glaucoma prevents this from happening. This fluid can increase the pressure inside your eye, causing damage to the optic nerve.

Who's at Risk for Glaucoma?

Many factors can put a person at risk for glaucoma, and the factors can vary based on the type of glaucoma that develops. The following are some of the most common risk factors for glaucoma.

Over the Age of 40

Glaucoma tends to affect the older population more than the young. Of the more than 3 million Americans currently living with glaucoma, approximately 2.7 million are above the age of 40. 

African American or Hispanic Origin

African Americans and Hispanics are three to four times more likely to develop glaucoma than Caucasians. 

A Family History of Glaucoma

Genetics play a part in developing glaucoma. If you have a family history of glaucoma, you're at a higher risk for developing the disease.

I travel from Central Phoenix there because they do through eye exams checking for pressure on the eyes, displaying them and looking at the optic nerve. They eye doctor there informed me I had high blood pressure from looking into my eyes. I went to the doctor and got on medication ASAP! He prevented me from having many other problems. That is why I go there.

Dr. Yates was very nice and helpful with my concern for my left eye.

He was on call and responded quickly to my message I left.

When I arrived in the office early that morning my wait time was minimal. I really appreciated being helped.

What's a Healthy Range for Eye Pressure?

High eye pressure can increase your risk for glaucoma.

​Healthy Eye Pressure: 10-20 mm HG, High Eye Pressure: 35+ mm HG

* Information from the American Academy of Opthalmology

Signs of High Eye Pressure

Increased intraocular pressure isn't always uncomfortable, and you may not see any symptoms. However, as the pressure continues to increase, you may start to feel pain in your eye or the surrounding areas. Other symptoms of growing eye pressure may include an upset stomach or eyesight changes.

How Is Glaucoma Diagnosed?

Dr. Justo and medical optometrists Mark Yates and Daniel Valdes use advanced tools to diagnose glaucoma. This includes the CIRRUS™ optical coherence tomography (OCT) test, which obtains a detailed picture of your eye. Our eye care professionals serving the greater Phoenix, AZ, area may also have you take a visual field test to examine your peripheral vision. During your visit, we will check the pressure of your eye as well. We also offer several noninvasive, highly effective options to monitor and treat glaucoma.

How to Prevent and Manage Glaucoma

Regular Eye Exams

Eye exams are the only way to determine if you have glaucoma. Attending regular eye exams at our offices in the Phoenix, AZ, area will allow our eye care professionals to detect glaucoma early and prevent the progression of the disease.

Knowledge of Genetic History

While a family history of glaucoma does not mean you're guaranteed to develop the in the future, it does increase your chances. Knowledge of your family history can help you take a proactive approach to prevention.

Regular Exercise

Maintaining an exercise routine may help reduce eye pressure. Since conditions such as diabetes and high blood pressure can increase your chances of developing glaucoma, it’s crucial to eat a balanced diet and remain active.

Quit Smoking

Smoking is linked to a number of health issues, which includes an increased risk of high eye pressure, cataracts, and other eye diseases. Avoiding tobacco products can help you maintain your vision.

Eye Protection

Severe eye trauma can lead to glaucoma, which is why it's important to use eye protection when performing activities that can harm the eyes.

Preserve Your Healthy Vision With Routine Eye Exams

Have you noticed a sudden onset of eye pain, halos around light sources, or changes in your peripheral vision?

You may have open-angle glaucoma or angle-closure glaucoma. This eye disease is treatable, so please visit us if you suspect you have symptoms.

During each eye appointment, we will measure your eye pressure and see if we can observe any symptoms of glaucoma. If we do diagnose you with this condition, Dr. Justo can begin treatment to improve your ocular health.

If you are experiencing symptoms of glaucoma or want to schedule a vision care appointment, contact our offices in the Phoenix, AZ, area. You can also call us at:

Glaucoma Treatment Options

Glaucoma is incurable, but professional treatment can manage intraocular pressure and help prevent further vision loss.
Glaucoma is incurable, but professional treatment can manage intraocular pressure and help prevent further vision loss.

Monitoring Your Condition

In the early stages of open-angle glaucoma, we may simply monitor your condition. As the disease progresses, we can recommend the treatment that is best suited to your needs. 

Eye Drops 

The first step in preventing the progression of glaucoma is regularly using prescription eye drops. If diagnosed with glaucoma, Dr. Justo or one of our medical optometrists will prescribe eye drops to help decrease the amount of fluid your eye makes or help the fluid drain better to reduce eye pressure. One or more prescription eye drops may be prescribed for your condition. 

Oral Medication

If eye drops aren't helping to lower your eye pressure, your eye doctor may prescribe oral medication to help reduce it.


If noninvasive methods aren't slowing down the progression of your glaucoma, your doctor may recommend surgery, such as argon laser trabeculoplasty. The extremely precise argon laser will clear the tissues that are blocking the drainage channel in your eye.

Your eye doctor may also perform an argon laser iridotomy to treat closed-angle glaucoma. During this procedure, your doctor will create an opening in your iris, allowing fluid to drain from your eye.

Recovering From Glaucoma Surgery

Following a laser procedure, you will need to maintain ongoing visits with Dr. Justo or one of our medical optometrists. This will allow us to monitor your progress and determine the best course of action moving forward.

In severe cases, you may require more extensive surgery. Dr. Justo can refer you to a local surgeon and will provide ongoing monitoring after your procedure.
