Corneal Mapping

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 office 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.

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.

  • An  Optomap® Retinal Exam provides your doctor with a retinal scan showing the health of your eye, and early detection of eye diseases such as macular degeneration, glaucoma, retinal tears and other health issues.  Your retinal scan becomes a permanent record in your file, enabling your eye doctor to review previous images.
  • A visual field test is designed to measure your peripheral vision. The test tests your vision using flashing lights, and you have to indicate when you see the light by pressing a button. There are no eye drops involved in this test.
  • Digital Retinal Imaging is the newest cutting-edge technology that we now use to detect eye disease at an early stage. Using this technology, eye doctors are able to treat eye disease earlier and save vision. Retinal images are stored electronically so that you and your doctor have a permanent record of the health of your retina.
  • Corneal topography is an imaging technique which maps the surface curvature of the cornea. This three-dimensional map helps to diagnose and treat several different eye conditions, and aids in plans for refractive surgery and contact lens fitting. The procedure is easy and painless.
  • Visual Field analysis is a test used to monitor peripheral vision, and detect and vision loss due to glaucoma and other eye conditions. The new Matrix technology uses frequency doubling technology (FDT) with is a type of light that the eye detects more clearly than white or yellow light.
  • The M’eyeFit is an amazing tool to personalize frames and maximize your vision. It is generally used to help with progressive lenses and bifocals, to ensure that the reading power is located in the correct place on the lens. It also measures several variables regarding the relationship of the lens to the eye that can affect vision, and therefore the patient experience with the glasses.
  • An aberrometer is used to determine what, if any, imperfections exist in the cornea and lens of the eye. When imperfections exist, light received by the eye will not focus properly, and will cause distortions in vision. The aberrometer measures the wave of light as it passes through the eye, and creates a map of the wave. Each patient will have an individual map, no two maps will be alike. The map is used to assist eye doctors in accurately prescribing glasses and contact lenses to improve vision.
  • The Kowa Digital Fundus Camera takes photos of the back of the eye, with a primary focus on the optic nerve, as well as the macula and the blood vessels in the back of the eye. The camera is important for monitoring changes inside the eye, and helps eye doctors determine treatment plans for patients with glaucoma, macular degeneration, diabetes, and other eye conditions.
  • The GDx optic nerve fiber analyzer is generally used to assess a patient's risk and progression of glaucoma, which is a disease that affects the optic nerve. The GDx detects changes in the optic nerve before vision is affected, allowing patients to begin treatment much earlier than before this technology was developed.
