Glaucoma Testing & Treatment

To detect glaucoma, our ophthalmologist will test your visual acuity and visual field as well as the pressure in your eye. Regular eye exams help to monitor the changes in your eyesight and to determine whether you may develop glaucoma.

During a glaucoma evaluation, your ophthalmologist will perform the following tests:

Tonometry

Tonometry measures your IOP by determining how your cornea responds when an instrument (or sometimes a puff of air) presses on the surface of your eye. Eyedrops are usually used to numb the surface of your eye for this test.

Gonioscopy

For this test, your ophthalmologist inspects your eye’s drainage angle the area where fluid drains out of your eye. During gonioscopy, you sit in a chair facing the microscope used to look inside your eye. You will place your chin on a chin rest and your forehead against a support bar while looking straight ahead. The goniolens is placed lightly on the front of your eye, and a narrow beam of light is directed into your eye while your doctor looks through the slit lamp at the drainag angle.Drops will be used to numb the eye before the test.

Ophthalmoscopy

With this test, your ophthalmologist can evaluate whether or not there is any optic nerve damage by looking at the back of the eye (called the fundus). There are two types of ophthalmoscopy: direct and indirect. With direct ophthalmoscopy, your ophthalmologist uses a small flashlight-like instrument with several lenses that magnifies up to about 15 times. With indirect ophthalmoscopy, the ophthalmologist wears a headband with a light attached and uses a small handheld lens to look inside your eye. Indirect ophthalmoscopy allows a better view of the fundus, even if your natural lens is clouded by cataracts.

Visual field test

The peripheral (side) vision of each eye is tested with visual field testing, or perimetry. For this test, you sit at a bowl-shaped instrument called a perimeter. While you stare at the center of the bowl, lights flash. Each time you see a flash, you press a button. A computer records your response to each flash. This test shows if you have any areas of vision loss. Loss of peripheral vision is often an early sign of glaucoma.

Photography

Sometimes photographs or other computerized images are taken of the optic nerve to inspect the nerve more closely for damage from elevated pressure in the eye.

Special imaging

Different scanners may be used to better determine the configuration of the optic nerve head or retinal nerve fiber layer.

Each of these evaluation tools is an important way to monitor your vision to help ensure that glaucoma does not rob you of your sight. Some of these tests will not be necessary for everyone. Your ophthalmologist will discuss which tests are best for you. Some tests may need to be repeated on a regular basis to monitor any changes in your vision caused by glaucoma.

Well, tried to make an appointment using their web site. I entered my information for a specific doctor for a specific... time. I got an email saying, I would hear back from them in 24 hours to confirm. 24 hrs later, I hadn't heard, so I called (per their email). The person answering the phone asked me for the exact same information, and then told me that the doctor I wanted to see wasn't available for another 5 months. Argh - an hour wasted. Just call them directly - do not use their stupid web site. BTW - because I couldn't get to see the doctor for 6 weeks, I went elsewhere.read more

I am very disappointed. First of all it took me almost a month to get this appointment and when I got there they asked... me all the standard covid questions and since I had gone out of state to Virginia, which is only about 10 minutes away from where I live in Maryland, I was told that I needed to reschedule two weeks out. I know they are trying to be safe but this is a little overkill and at least someone could’ve called me or reached out to me prior to the appointment to find out if I’ve been out of state if this is a new policy of theirs. I just feel that it was very inconsiderate to cancel my appointment after I had already taken the time to go there. You know I would have to give them 24 hours to cancel without being charged a cancellation fee. I mean my time is important and valuable as well.read more

This office does a very complete check of my eyes and eyesight. The equipment used checks my eyes thoroughly and checks... all aspects of my eyesight. Dr. Chen reviews the test and pictures taken with the equipment with me when he does his part of the exam. I feel that know the status of my eyes and that I am aware of how I would know if anything were not working as it should. When I leave I know that everything has been explained to me and I know exactly what the status of my eyes and eyesight is. This is the best ophthalmologist I have ever gone to!read more

Central MD Eye Associates is a well oiled machine. From start to finish, everyone knows their job, executes well, and... makes it a pleasant experience. The only thing slowing these folks down is waiting for drops to take effect. Been a patient for over 10 years. Expertise is top notch from Dr. Gross on down. State of the art tech equipment. Very highly recommended.read more

I have been going to Central Maryland Eye for several years, and have felt the staff very caring and the doctors... extremely caring and excellent in the treatment of their patients. I have had cataract surgery and the patience Dr. Amy Nicholas and Debbie made me feel very much at ease. To my surprise Dr. Nicolas called me the evening after my surgery to check whether I was doing okay.read more

The office staff and Dr. Gross are great. The only reason I did not give 5 stars is that I wanted to be examined for... contacts and was told I could schedule an appointment with the optometrist in the office only to find out he does not accept my insurance (Cigna Vision). I found it very inconvenient! Would have liked to stay with the office I have been going to for my eye care for years!read more

This was my first visit to this office. The moment I walked into the office, they checked my temperature and asked me... several questions about symptoms and any possible exposure to COVID-19. Face masks are mandatory and are provided in the event someone forgets to bring one. The office was attractive, clean, welcoming, and seating chairs in the reception area were comfortably spaced. The office atmosphere was friendly, unhurried and efficient. The receptionist welcomed me and asked me to complete forms regarding my medical history, vision problems, my chief concerns, and other routine items. I was seen on time by Dr. Amy Nicholson, who greeted me in a friendly manner, was gentle and thorough in her examination of my eyes, reviewed my medical history, and provided me with important information about my eyes. It's a wonderful office and I highly recommend it to anyone looking for an ophthalmologist.read more

Wonderful how friendly and relaxed that every EVERYONE was!!! Each person made me feel like I was "family" which being... from Pennsylvania I liked very much. Also when doing tests everyone explained things or allowed me to ask questions. Also, Dr. Gross spent a lot of time examining my test results and gave me the best recommendations to make my vision better.read more
