Glaucoma refers to a group of eye conditions that can cause irreversible vision loss and eventual blindness without proper treatment. 

We provide glaucoma diagnosis and treatment, with exceptional service at every stage of care.

At Primary Eye Care Associates in Chicago, IL, we have a dedicated glaucoma center equipped with advanced technology.

Types of Glaucoma

In a normal eye, aqueous humor (the fluid between the lens and cornea) circulates in and out of the eye continually. When the fluid fails to circulate and exit the eye, glaucoma can develop. This condition causes damage to the optic nerve due to abnormally high intraocular pressure (pressure within the eye). The most common type of glaucoma develops gradually, and may not become apparent to the sufferer until vision is permanently affected, so it is important to undergo regular eye exams.

There are several types of glaucoma:

Open-Angle Glaucoma

By far the most common type, open-angle glaucoma occurs when the drainage canals within the eye slowly become clogged. Symptoms of open-angle glaucoma often do not become apparent to the sufferer until vision loss has occurred. In open-angle glaucoma, vision loss begins in the periphery, and can progress to tunnel vision.

Angle-Closure Glaucoma

In angle-closure glaucoma, symptoms develop suddenly, and can include eye pain, nausea, halos around lights, and blurred vision. Angle-closure glaucoma is considered an emergency requiring immediate medical attention.

Normal-Tension Glaucoma

In normal-tension glaucoma, the optic nerve becomes damaged even though intraocular pressure within the eye is normal.

Congenital Glaucoma

Congenital glaucoma affects infants and young children, and can occur when an infant's eye fails to develop proper drainage canals, causing increased eye pressure.

Glaucoma Diagnosis

It is important to establish a routine of regular eye exams to detect vision conditions in the earliest stages. We have several methods of diagnosing glaucoma during your eye exam.

OCT Test

We offer optical coherence tomography (OCT), which uses ultrasound to detect optic nerve damage. It involves a quick scan that takes about 25 seconds for each eye. The OCT test is like taking an MRI of the optic nerve fiber layer, allowing for the earliest detection of glaucoma and changes in advancing glaucoma so we can stay ahead of vision loss.

The fee for the ICT 3D imaging test of the optic nerve is $95, and it is recommended once a year for glaucoma patients. Patients that are at increased risk of glaucoma should undergo the OCT test every four years after age 50.

Other Glaucoma Tests

Visual Field Test

An examination of your full range of vision can reveal glaucoma symptoms. This test typically involves placing a light source around your peripheral vision to test its range.

Family History

During your exam at our Chicago practice serving Midway, Garfield Ridge, and surrounding areas, we will discuss whether any members of your family have glaucoma. A family history of the condition can increase your risk of developing glaucoma, and routine testing should be performed.

Eye Pressure Evaluation and Corneal Thickness

We perform a corneal biometry and ultrasound test that takes just a few seconds per eye. This evaluation measures corneal thickness and enables us to more accurately analyze eye pressure. The fee is $23.50 for each eye.

Neurological Visual Field Testing

Advanced neurological visual field testing evaluates the integrity of peripheral vision, where glaucoma typically starts to damage vision. This test tracks the progression of glaucoma and can diagnose brain disorders such as mini stroke, aneurysm, and tumors. We charge $67 per eye for this test.


This advanced 3D imaging system creates a full digital image of your retina, which can reveal where damage has occurred. The optomap® test can also identify conditions such as macular degeneration and diabetic retinopathy, which can be related to glaucoma.

Drainage Angle Test

After placing a special contact lens in your eye, Dr. Chander can identify a blocked or narrowed drainage angle.

Glaucoma Treatment

The team at Primary Eye Care Associates will create a personalized glaucoma treatment plan for you. Although existing optic nerve damage cannot be repaired, glaucoma can be monitored and controlled to prevent further vision loss.

Ocular Nutrition

We offer ocular nutrition for glaucoma to increase the blood flow to the optic nerve for advanced nerve protection and to enhance the efficacy of glaucoma medications. The cost of ocular nutrition therapy is $34.95 a bottle.

Eye Drops

In some cases, eye drops are the simplest way to control glaucoma. By applying prescription eye drops several times a day, you can reduce the production of aqueous, thereby alleviating internal pressure.

Eye Surgeon

Minimally Invasive Glaucoma Surgery with OMNI

Advanced minimally invasive glaucoma surgery (MIGS) may be recommended for patients that forget to put in eye drops, need to reduce the number of required medicines to lower eye pressure, or for those that are allergic to medications.

We perform this procedure using the state-of-the-art OMNI® tool, which allows us to create just one corneal incision and treat the drainage canals of the eyes. After surgery, patients experience a reduction in eye irritation, the need for eye drops, and medication co-pays, among other benefits.



We can remove precise amounts of tissue with a laser to open the drainage channel and reduce intraocular pressure. The use of a laser makes the procedure less invasive and can result in a quicker and more comfortable recovery.

Peripheral Iridotomy

If you suffer from closed-angle glaucoma, peripheral iridotomy can reshape the part of the iris that is blocking the drainage angle.
