Comprehensive Medical Eye Exam

Periodic eye and vision examinations are an important part of preventive health care. Many eye and vision problems have no obvious signs or symptoms. As a result, individuals are often unaware that problems exist. Early diagnosis and treatment of eye and vision problems are important for maintaining good vision and eye health, and when possible, preventing vision loss.

A comprehensive adult eye and vision examination may include, but is not limited to, the following tests. Individual patient signs and symptoms, along with the professional judgment of the doctor, may significantly influence the testing done.

Patient History

A patient history helps to determine any symptoms the individual is experiencing, when they began, the presence of any general heath problems, medications taken and occupational or environmental conditions that may be affecting vision. The doctor will ask about any eye or vision problems you may be having and about your overall health. The doctor will also ask about any previous eye or health conditions of you and your family members.

Visual Acuity

Reading charts are often used to measure visual acuity. Visual acuity measurements evaluate how clearly each eye is seeing. As part of the testing, you are asked to read letters on distance and near reading charts. The results of visual acuity testing are written as a fraction such as 20/40.

When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet in order to see it clearly. Normal distance visual acuity is 20/20.

Preliminary Tests

Preliminary testing may include evaluation of specific aspects of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils respond to light.

Keratometry

This test measures the curvature of the cornea, the clear outer surface of the eye, by focusing a circle of light on the cornea and measuring its reflection. This measurement is particularly critical in determining the proper fit for contact lenses.

Refraction

Determining refractive error with a phoropter and retinoscope. Refraction is conducted to determine the appropriate lens power needed to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Using an instrument called a phoropter, your ophthalmologist places a series of lenses in front of your eyes and measures how they focus light using a hand held lighted instrument called a retinoscope. The doctor may choose to use an automated instrument that automatically evaluates the focusing power of the eye. The power is then refined by patient’s responses to determine the lenses that allow the clearest vision.

This testing may be done without the use of eye drops to determine how the eyes respond under normal seeing conditions. In some cases, such as for patients who can’t respond verbally or when some of the eyes focusing power may be hidden, eye drops are used. The drops temporarily keep the eyes from changing focus while testing is done.

Eye Health Evaluation

Tonometry measures eye pressure. Elevated pressure in the eye signals an increased risk for glaucoma. External examination of the eye includes evaluation of the cornea, eyelids, conjunctiva and surrounding eye tissue using bright light and magnification.

Evaluation of the lens, retina and posterior section of the eye may be done through a dilated pupil to provide a better view of the internal structures of the eye.

Measurement of pressure within the eye (tonometry) is performed. Normal eye pressures range from 10 to 21 millimeters of mercury (mm Hg), averaging about 14 to 16 mm Hg. Anyone with eye pressure greater than 22 mm Hg is at an increased risk of developing glaucoma, although many people with normal pressure also develop glaucoma.

Supplemental testing

Additional testing may be needed based on the results of the previous tests to confirm or rule out possible problems, to clarify uncertain findings, or to provide a more in-depth assessment.

At the completion of the examination, your ophthalmologist assess and evaluate the results of the testing to determine a diagnosis and develop a treatment plan. He or she will discuss with you the nature of any visual or eye health problems found and explain available treatment options.

If you have questions regarding any eye or vision conditions diagnosed, or treatment recommended, don’t hesitate to ask for additional information or explanation from your doctor.

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
