We use the most up-to-date technology to ensure the best eye care possible. Here are some of the different types of tests and equipment you may experience on a visit to Brookfield Vision Care.
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topography is of critical importance in determining the quality of vision.
The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Digital Retinal Imaging & OCT Scans
We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal Images will be stored electronically. This gives the eye doctor a permanent record of the condition and state of your retina.
This is very important in assisting your Optometrist to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.
The advantages of digital imaging include:
- Quick, safe, non-invasive and painless
- Provides detailed images of your retina and sub-surface of your eyes
- Provides instant, direct imaging of the form and structure of eye tissue
- Image resolution is extremely high quality
- Uses eye-safe near-infra-red light
- No patient prep required
Digital Retinal Imaging
Digital Retinal Imaging allows your eye doctor to evaluate the health of the back of your eye, the retina. It is critical to confirm the health of the retina, optic nerve and other retinal structures. The digital camera snaps a high-resolution digital picture of your retina. This picture clearly shows the health of your eyes and is used as a baseline to track any changes in your eyes in future eye examinations.
Optical Coherence Tomography (OCT)
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an CT scan of the eye. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease.
With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.
An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our Brookfield eye care center to inquire about an OCT at your next appointment.
Visual Field Testing
A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient’s ability to understand and follow instructions.
An initial visual field screening can be carried out by the optometrist by asking you to keep your gaze fixed on a central object, covering one eye and having you describe what you see at the periphery of your field of view. For a more comprehensive assessment, special equipment might be used to test your visual field. In one such test, you place your chin on a chin rest and look ahead. Lights are flashed on, and you have to press a button whenever you see the light. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating. Each eye is tested separately and the entire test takes 15-45 minutes. These machines can create a computerized map out your visual field to identify if and where you have any deficiencies.
Our eye care clinic in Brookfield, CT is proud to use the Humphrey Field Analyzer 3 (HFA3) from ZEISS, in our optometry office.
OPTOS Retinal Exam
Annual eye exams are vital to maintaining your vision and overall health. We offer the optomap® Retinal Exam as an important part of our eye exams. The optomap® Retinal Exam produces an image that is as unique as you fingerprint and provides us with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera.
Many eye problems can develop without you knowing. You may not even notice any change in your sight. But, diseases such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.
An optomap® Retinal Exam provides:
- A scan to show a healthy eye or detect disease.
- A view of the retina, giving your doctor a more detailed view than he/she can get by other means.
- The opportunity for you to view and discuss the optomap® image of your eye with your doctor at the time of your exam.
- A permanent record for your file, which allows us to view your images each year to look for changes.
The optomap® Retinal Exam is fast, easy, and comfortable for all ages. To have the exam, you simply look into the device one eye at a time and you will see a comfortable flash of light to let you know the image of your retina has been taken. The optomap® image is shown immediately on a computer screen so we can review it with you.

With California, Optos has incorporated new hardware and software technology enabling practitioners to see more, discover more and eﬀectively treat more ocular pathology thus promoting patient health.
In addition to the benefits found with all of the UWF devices from Optos such as 200 degrees or up to 82% of the retina captured in a single image, in multiple modalities, as well as eye care professionals being able to see 50% more of the retina when compared to other conventional imaging devices, California af, offers the following benefits:
– Motorized head and chin rest to more easily assist those patients requiring additional assistance during imaging
– Multiple imaging modalities including; 3-in-1 color depth imaging (color, red-free and choroidal in a single image) as well as Autoﬂuorescence
Optical Coherence Tomography (OCT) has dramatically changed the way eye care professionals visualize the retina, the optic nerve, and anterior segment structures. Not surprisingly the way diseases associated with these anatomical structures are diagnosed and managed has transformed as well.
Optovue OCT has a broad range of applications in today’s eye care practices. OCT technology generates high-resolution, cross-sectional and three-dimensional (3D) images of the retina, optic disc and anterior segment, to give you valuable information that aids in the diagnosis and management of a range of ocular diseases.
Diverse Views of the Retina
In addition to cross-sectional images of retinal tissue, Optovue OCT systems include dense 3D cubes of data that can be dissected to visualize individual retinal layers in an en face view and thickness maps with normative comparison. With this information, you gain new insights into the health of the retina to increase diagnostic confidence and measure your patient’s response to treatment.
In-Depth Analysis of Nerve Fiber Layer Structures
OCT technology is transforming the way physicians assess nerve fiber layer thickness, ganglion cell complex thickness, and a range of parameters on the optic disc. Optovue OCT systems utilize advanced software to provide extensive analysis of optic disc structures in simple, easy-to-read reports.
Anterior segment OCT further expands the role of OCT in clinical practice and gives you the ability to visualize cross sections of the cornea, see and measure corneal angles, measure and track corneal thickness over multiple visits, and calculate IOL powers in post-refractive surgery patients.
iCare Tonometers are used for easy, accurate and patient-friendly intra-ocular pressure measurement, which is used for glaucoma screening. iCare tonometers are based on unique, patented rebound technology, in which a very light and small probe is used to make momentary contact with the cornea. The Icare tonometer is based on a proven accurate measuring principle, in which a very light probe is used to make momentary and gentle contact with the cornea. The measurement is barely noticed by the patient. The device not only makes IOP measuring a more pleasant experience on all patients, it is also an important break-through for succeeding with non-compliant patients (i.e. children and dementia patients).
VEP (Visual Evoked Potential)
Visual Evoked Potential (VEP) measures the electrical response from a visual stimulus. A checkerboard or some other visual stimulus is placed in front of a patient, and electrodes are placed on the persons head to measure the electrical response of the patients’ eyes.
The patient is not required to give any verbal response, which makes this test perfect for young children, infants and those with communicative challenges.
