Digital Retinal Imaging

The auto-refractor is a digital refractor that works much the same way as the old fashioned phoropter. The big difference is that, instead of the doctor manually clicking through, asking you to decide for yourself which lens is best (which is especially hard when the lenses are very nearly the same!), the auto-phoropter is controlled electronically and measurements are done digitally. This not only shortens the amount of time it takes to decide which lenses will provide you your best vision correction (super helpful when trying to get your little one to stop squirming and co-operate with the process!), but also ultimately results in a more accurate eyeglasses or contact lens prescription

We are proud to use Marco’s latest generation of electronic refraction technology, the TRS 5100, in our office.

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.

We are proud to use the Medmont E300 Corneal Topographer, a computerized video-keratometer, in our office.

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 our optometrists 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 preparation required

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.

We are proud to introduce the latest cutting edge technology in retinal imaging, the Optos Daytona Optomap OCT. This amazing device allows your eye doctor to see retinal, optic nerve and cornea structures not visible through regular exam methods by using light to provide a high resolution scan meant to pick up early signs of structural change or disease. Your eye doctor will see even the smallest changes in the retina and optic nerve with greater accuracy, and much higher definition, making early and accurate detection of common sight threatening eye conditions such as glaucoma, macular degeneration and diabetic retinopathy, easier than ever before. While traditional imaging technologies are usually able to scan around 15% of your retina at a time, The OPTOS Optomap is able to scan in a stunningly large 200 degree arc, capturing about 80% of your retina in one panoramic scan. This allows for a wider and more accurate view of the retina than with less advanced scans. This scan will provide you and your eye doctor with an extremely detailed picture of your eye that will act as a valuable road map of your overall eye health. The high resolution images produced by the Optos Daytona Optomap OCT provide a personal benchmark for each person’s ocular health and helps detect sudden changes through the years, and since the images show up automatically on a computer monitor, you are able to see for yourself everything the doctor is telling you about your eye health, allowing you to take an active role in preserving your valuable sense of sight. The patient experience is also fast, easy and painless. Nothing touches your eye at any time and it is suitable for the whole family, from youngest to oldest. The exam consists of taking a brief look into the device one eye at a time. You will see a comfortable flash of light, which lets you know the image of your retina has been taken, and you’re done!

A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula.The resulting photograph is a high resolution magnified image which can help to assess for eye conditions including glaucoma, diabetic retinopathy, macular degeneration, optic nerve disease, and many others. This picture also gives us a baseline to compare the state of your eye health in the future.

We are proud to use the Zeiss VISUCAM 524 fundus camera, with a 24-megapixel sensor, in our eyecare office.

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, optometrists 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.

We are proud to use the Cirrus HD-OCT 5000 system, featuring a modernized system based on a faster processing system, in our eyecare office.

A tonometer is used to measure intraocular pressure (IOP), which is the pressure inside your eye. A tonometry test is primarily used to check for glaucoma, which is a serious eye disease that can lead to blindness if not treated properly. There are several types of tonometers, including a non-contact tonometer that uses air and does not require eye drops. No matter which type of tonometer your eye doctor uses, the test is painless.

A non-contact tonometer (also knows as a “puff test”) measures the pressure in the eye. This is an important test for glaucoma screening, which is a serious eye disease that can lead to blindness if not treated. The puff of air measures the pressure in the eye by flattening the cornea in a non-invasive manner.

A visual field test measures how much ‘side’ vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check if you are concentrating. Each eye is tested separately and the entire test takes 6-15 minutes. Normally the test is carried out by a computerized instrument, called a Humphrey Visual Field Analyzer. Visual Field testing can help detect eye conditions such as glaucoma, migraines, multiple sclerosis, and neurological conditions such as brain tumors and aneurysms.

Our office is proud to use the Humphrey Field Analyzer 3 (HFA3) from ZEISS, in our optometry office.
