Annual eye exams are vital to maintaining your vision and overall health. Dr. Plow and Dr. O’Connor recommend beginning all comprehensive eye exams with the latest in eye imaging systems, the Optomap® Retinal Exam. The Optomap® Retinal Exam produces an image that is as unique as your fingerprint and provides our doctors 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.
Like its predecessors in the Optos family, Daytona provides an unequaled 200° view of the retina in a single capture. The result is a high-resolution, high-contrast image – the Optomap. This comprehensive view of up to 82% of the retina in one image, gives our doctors the opportunity to identify and follow changes in your eye health.
Optos has 100 completed and ongoing clinical studies that support how Optomap’s ultra-wide view of the retina helps eye care professionals like Dr. Plow and Dr. O’Connor provide the best care for their patients. The high-resolution digital images can be easily stored for later study, future reference or comparison, and shared with other providers.
The newest generation of Optos technology, Daytona, has been specifically redesigned to provide ultra-high resolution imaging, and adding new ultra-wide field auto-fluorescence capabilities. Weighing only about 60 pounds, Daytona’s new, ergonomic body is designed to increase patient comfort, as well as make it easier to correctly position the eye. The new Daytona imaging system is featured in the video above.
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.
What is an OCT scan?
Optical Coherence Tomography (OCT) is a new imaging technique that provides unprecedented high resolution and cross-sectional images of the eye. The OCT scan allows microstructures of the eye to be imaged and shows different colour-coded layers of the retina. It is particularly useful in the diagnosis and management of eye conditions such as age-related macular degeneration, diabetic macular oedema, macular hole, epiretinal membrane, vitreo-macular traction syndrome and glaucoma. It has also become a gold standard in monitoring the efficacy of intravitreal anti-VEGF injections (Avastin or Lucentis) for age-related macular degeneration and tailoring treatment regime.

Digital Retinal Photography
Retinal photography assists in the detection and management of conditions such as macular degeneration, hypertensive retinopathy, optic nerve disease, diabetic changes and retinal holes or thinning.
By taking high-resolution pictures inside the eye, we can use a digital imaging system to record a detailed photo of the retina.
Corneal topography is a computer assisted diagnostic tool that creates a three-dimensional map of the surface curvature of the cornea. The cornea (the front window of the eye) is responsible for about 70 percent of the eye’s focusing power. An eye with normal vision has an evenly rounded cornea, but if the cornea is too flat, too steep, or unevenly curved, less than perfect vision results. The greatest advantage of corneal topography is its ability to detect irregular conditions invisible to most conventional testing.
Corneal topography produces a detailed, visual description of the shape and power of the cornea. This type of analysis provides your doctor with very fine details regarding the condition of the corneal surface. These details are used to diagnose, monitor, and treat various eye conditions. They are also used in fitting contact lenses and for planning surgery, including laser vision correction.
Computerized corneal topography can be beneficial in the evaluation of certain diseases and injuries of the cornea including:
The corneal topography equipment consists of a computer linked to a lighted bowl that contains a pattern of rings. During a diagnostic test, the patient sits in front of the bowl with his or her head pressed against a bar while a series of data points are generated. Computer software digitizes these data points to produce a printout of the corneal shape, using different colors to identify different elevations, much like a topographic map of the earth displays changes in the land surface. The non-contact testing is painless and brief.
