Overview
What Is Glaucoma?
Glaucoma is a disease that damages your eye’s optic nerve. It usually happens when fluid builds up in the front part of your eye. That extra fluid increases the pressure in your eye, damaging the optic nerve.
Glaucoma is a painless condition commonly associated with slow, progressive loss of peripheral vision. Glaucoma is usually not noticed by the patient, but it is a leading cause of blindness in adults, and the risk increases as you age. But blindness from glaucoma can often be prevented. There are glaucoma treatments available for anyone in the Washington, DC area. The key to preventing serious vision loss or blindness from glaucoma is an annual, comprehensive eye examination.
Who Is at Risk for Glaucoma?
- Age. Your risk for developing glaucoma increases as you get older. This risk develops after the age 40 and continues to increase with each additional decade.
- Race. Chronic glaucoma is three to four times more common in African-Americans than in whites. Also, African-Americans are more likely to develop an aggressive form of the disease at a younger age.
- Family history. Your risk of developing glaucoma substantially increases if first degree family member such as a parent or sibling has glaucoma.
- Certain medical problems. Diabetes Mellitus, heart disease, and history of extreme nearsightedness are risk factors for glaucoma development.
- Medications. Chronic use of steroid creams, ointments, oral, inhalers, or injections increases the risk of developing higher pressure, which invariably increases your risk of developing glaucoma.
- Associated eye issues. Patients with rigid ocular tissue, thin ocular outer surface (cornea), and/or with unique ocular conditions the clog-up the eye drainage systems such as ocular inflammation (Uveitis), ocular pigmentary sluffing (Pigmentary Dispersion Syndrome) or ocular protein sluffing (Pseudoexfoliation Syndrome) are at higher risk of developing glaucoma.
Glaucoma Detection Screening and Diagnosis at Visionary Eye Doctors
Early detection through regular and complete eye exams is the key to protecting your vision from damage caused by glaucoma. A complete eye exam includes various tests to accurately diagnose glaucoma. It is important to have your eyes examined regularly as for most people there are usually few or no symptoms of glaucoma. At Visionary Eye Doctors, our physician Thandeka Myeni, MD is a board-certified ophthalmologist and is fellowship-trained in glaucoma. To learn more about Dr. Myeni, click here. Glaucoma is known as the silent thief of sight. Request to schedule a comprehensive eye exam appointment with Dr. Myeni here.
Get regular eye exams:
- Before age 40 – every two or three years
- From age 40 to age 54, every one to three years
- From age 55 to 64 – every one to two years
- After age 65 – every six to 12 months
The first sign of glaucoma is often the loss of peripheral, or side vision, which can go unnoticed until late in the disease. Detecting glaucoma early is one reason you should have a complete exam with an eye specialist every one to two years. To make the diagnosis of glaucoma, we take into consideration a number of factors, such as the appearance of your optic nerves and your eye pressures; the results of a number of diagnostic tests such as corneal thickness, nerve fiber thickness, and visual field testing; and risk factors for glaucoma such as your age, family history of glaucoma, race, and your general health. If glaucoma has been detected, it’s best to start your glaucoma treatment as soon as possible. We offer trusted glaucoma treatments in the Washington, DC area.
There Are Two Main Types of Glaucoma
Open-angle glaucoma – Also called wide-angle glaucoma, this is the most common type of glaucoma. The structures of the eye appear normal, but fluid in the eye does not flow properly through the drain of the eye, called the trabecular meshwork.
Angle-closure glaucoma – Also called acute or chronic angle-closure or narrow-angle glaucoma, this type of glaucoma is less common but can cause a sudden build-up of pressure in the eye. Drainage may be poor because the angle between the iris and the cornea (where a drainage channel for the eye is located) is too narrow.
How We Diagnose Glaucoma
At Visionary Eye Doctors, we offer innovative technology for early detection of glaucoma, such as visual field testing, visual evoked potential (VEP), and electroretinography (ERG) tests.
The term visual field refers to the area of a scene you can see with your eyes fixed on one location. For example, while watching a stop light, you may notice a car pulling up beside you in the next lane. Your peripheral vision enables you to see the movement of the car. The visual field is quite extensive when both eyes are working properly but with glaucoma, the field of view is reduced.
A visual field test measures two things:
- How far up, down, left and right the eye sees without moving.
- How sensitive the vision is in different parts of the visual field.
OCT (Optical Coherence Tomographer)
The OCT has the ability to capture images of eye tissue at a near individual cell level of resolution. In addition, it can show each layer of tissue in the eye allowing our glaucoma eye doctors to pinpoint the exact location of tissue damage. This sophisticated piece of equipment aids in the diagnosis and management of many ocular conditions, including glaucoma and macular degeneration. OCT is a safe, painless and quick procedure that does not require dilation of the pupils. A laser scans the retina, optic nerve, cornea, or anterior chamber in just a matter of seconds to provide our glaucoma doctors with detailed information regarding the microscopic details of the eye. Anyone who has glaucoma or is a glaucoma suspect would benefit from undergoing this diagnostic test.
Pachymetry
Pachmymetry is the measurement of the thickness of the cornea, the clear window on the front of the eye.
When the cornea is thinner than average, patients may have an increased risk of developing glaucoma. Pachymetry should be performed at least once in a glaucoma patient’s adult life if eye pressure seems too low to explain glaucomatous optic nerve damage or if the eye pressure is higher than one would expect.
Diopsys® NOVA Vision Test System
As advances in technology continue to change the field of eye care, Visionary Eye Doctors is proud to offer the very latest in eye disease management. To discover vision-related diseases in their earliest stages, we use the Diopsys® NOVA Vision Testing System. Through this state-of-the-art advancement in electrophysiological technology, we can effectively detect, diagnose, and monitor progress of treatment for conditions like glaucoma and macular degeneration at their earliest stages.
Our team makes use of both the VEP (Visual Evoked Potential) and ERG (Pattern Electroretinography) protocols to conduct objective, office-based vision testing. Before the process can begin, sensors are placed on the patient’s head similar to an electrocardiogram or EKG. With such a streamlined process, the Diopsys® NOVA technology provides the following advantages:
- No need for the patient to verbally respond or push any buttons
- Comfortable and relatively fast test
- Easy-to-understand reports for the most accurate physician interpretation
- Can help diagnose disorders as well as monitor treatment progress
The VEP and ERG tests each measure a specific area of the eye to thoroughly assess the function of the visual system.
Diopsys® NOVA-VEP (Visual Evoked Potential)
The Diopsys® NOVA-VEP measures the activity of the entire visual pathway. Results from this test can determine how well the entire visual system is functioning. This test can be performed on patients as early as six months or older to detect vision or optic nerve disorders. The VEP can also be used for patients who have developed neuro-visual problems following a traumatic brain injury or stroke. It can help determine if the optic nerve function is healthy or abnormal, as seen in multiple sclerosis and glaucoma.
Diopsys® NOVA-ERG (Pattern Electroretinography)
With the Diopsys® NOVA-ERG system, our team can determine the patient’s retinal function, which allows them to identify potential disorders. When used along with other diagnostic tests, like the VEP, this can help differentiate between a retinal and optic nerve disorder. The ERG can help detect these signs at a cellular level for earlier detection and a more timely treatment.
Considering the fact that visual diseases may develop differently, both the VEP and ERG tests are customized to the patient to fully understand their visual health. The entire process takes around 10 minutes, after which time we have instant access to the test results. The Diopsys® NOVA testing systems have proven to be an invaluable addition to our practice.
What Are My Treatment Options?
Glaucoma Eye Drops
With Visionary Eye Doctors, you have many options for glaucoma treatment in the Washington, DC area. Prescription Eye Drops for glaucoma help maintain the pressure in your eye at a healthy level and are an important part of the treatment routine for many people. It is important to notify your doctor of any other medications you may be taking (including over-the-counter items like vitamins, aspirin, and herbal supplements) and about any allergies you may have.
Treatment requires monitoring eye pressure and measuring changes in the peripheral visual field. Controlling glaucoma usually means maintaining eye pressure at an acceptable level when there has been little or no loss of the visual field.
We are one of the few centers in the Washington, DC metro area to offer our Glaucoma patients the Icare.
The Icare home tonometer is one of the first methods for 24HR monitoring outside normal clinic hours which may help identify IOP variations and spikes.
Self-tonometry with the Icare® HOME is designed to gather additional intraocular pressure (IOP) information by the patient. The device records IOP, date, time, eye and a quality score which is not displayed to the patient. The data is retrieved by a health care provider via Icare® LINK software.
Some of the most common procedures we offer to treat glaucoma include selective laser trabeculoplasty (SLT), laser peripheral iridotomy (LPI), trabeculectomy or shunt placement.
Micro-Invasive Glaucoma Surgery (MIGS)
The treatment for glaucoma has come a long way. Today’s advanced technologies and procedures make it possible to diagnose and successfully manage this progressive disease. And while the overall goal of treatment has always remained the same — reducing intraocular pressure (IOP) and glaucomatous progression — Micro-Invasive Glaucoma Surgery (MIGS) is quickly becoming a widely accepted approach for treating mild-to-moderate glaucoma.
Glaucoma Therapy Advances
Glaucoma is primarily managed with prescription eye drops. If a patient’s glaucoma progresses or the patient stops responding to the eye drops, a surgical solution is offered. These surgical solutions are often highly invasive, require long recovery times, and could result in long-term complications.
As technology has progressed, less invasive techniques have emerged that have improved the safety profile for glaucoma surgery. This opened more surgical options for patients interested in effective glaucoma management which does not rely solely on the continuous use of prescription medication.
With the FDA approval of the iStent®, Micro-Invasive Glaucoma Surgery (MIGS) became a preferred approach to glaucoma management for many eye care professionals and their patients with mild-to-moderate glaucoma.
Now, with the FDA approval of iStent inject® – the smallest medical device known to be implanted in the human body—is made of two tiny stents that are designed to restore your eye’s natural ability to drain fluid out of the eye to reduce glaucoma pressure. Designed for cataract patients with glaucoma, iStent inject® is implanted at the time of cataract surgery. You won’t see or feel the iStent inject® stents after they are inserted, but they are designed to effectively manage your eye pressure.
How iStent inject® Works
Similar to cardiac stents used in patients with heart problems, the iStent opens pressure drainage channels in the eye, permanently treating glaucoma. To help control the increased pressure in your eye associated with glaucoma, iStent inject® creates two bypasses, or openings, between the front part of your eye and its natural drainage pathway to increase the flow of fluid. By creating the permanent bypasses through the primary blockage site (trabecular meshwork), iStent inject® is designed to:
• Improve your eye’s natural outflow to safely lower intraocular pressure
• Work continuously to improve the natural flow of fluid in your eyes

Selective Laser Trabeculoplasty (SLT)
Selective laser trabeculoplasty (SLT) is a glaucoma laser procedure used to lower the pressure in the eye. SLT uses short pulses of low energy laser to target specific cells in the drainage system of the eye to stimulate improved function. Ultimately, the SLT procedure can slow or stop the risk of disease progression. The SLT technique is very gentle, and studies show that it does not damage the tissue of the drainage system. The treatment takes only a few minutes to apply, and there is typically no discomfort felt by the patient. Following the laser treatment, the patient usually continues any existing glaucoma drops.
