Technology – Advanced Eye Care

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 our Practice.

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.

SPECIAL TESTING MEANS EXTRA SPECIAL EYE CARE

Optical Coherence Tomography (OCT)

Our OCT helps us better manage glaucoma and diseases of the retina because this technology allows the eye doctor to see the deep tissue layers in the eye. These high-definition images are the only way that they can actually see beneath the surface to the nerve fiber layers where damage occurs. Up until now, eye doctors had to use other tests to indicate damage in this critical area of sight. Common eye diseases such macular degeneration, diabetic retinopathy, and glaucoma are detected early by the OCT when the diseases can be more effectively treated.

We recently upgraded to OCT with AngioPlex® which offers a major step forward in making retinal disease management and treatment planning more efficient and effective

 

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.

Fundus Camera

A high-definition digital image of the retinal area helps your eye doctor diagnose and manage eye diseases in the delicate retinal area. Damage to these delicate structures of the retinal area is often the first sign of systemic diseases such as MS, diabetes and more. The retina is the “window to the body” and routine retinal imaging can help your eye doctor monitor the changes in your eye health from year to year.

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.

The OCULUS Keratograph® 5

A groundbreaking piece of imaging equipment that changes the way we diagnose and treat eye diseases. This brand new machine is among the latest advances in optometry, it is especially useful for testing, diagnosing and treating dry eye disease.

The OCULUS Keratograph® 5M integrates a high definition camera, keratometer, and corneal topographer into one seamless and state-of-the-art imaging machine. Surface eye diseases are no match for this precise and innovative tool, which integrates with computer technology to create detailed, full-color digital images of your eye.

If you have dry eye disease, we will use the round camera lens to examine your Meibomian glands (also called your tarsal glands). These glands produce the oil layer of your tear film, which keeps them from drying out and evaporating. The Keratograph allows us test the break-up time of your tear film, the height of your tear meniscus, and the condition of your eye’s lipid layer
