Digital Imaging Technology: the latest in eye care advancements
The eye doctors at Armstrong & Small Eyecare Centre use cutting-edge digital imaging technology to assess your eyes. Many eye emergencies and 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 in Winnipeg 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
Optos Ultra-Wide Retinal Exam in Winnipeg, MB
The Daytona is our latest Ultra-Wide Retinal Imaging device that allows our 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, ultra-wide 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 at our optometry practice in Winnipeg.
All of our adult eye exams include the Optomap® Retinal Exam as an important part of our comprehensive eye exams. The Optomap® Retinal Exam produces an image that is as unique as your 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.
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.
We are proud to have the latest and most advanced in OCT technology - the Zeiss Cirrus HD OCT 5000.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the eye. It works using the 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.
Nidek OPD Scan
The Nidek OPD III refractive power and the corneal analyzer is the latest instrument acquired by Armstrong & Small Eyecare Centre to provide our doctors with the best information about your prescription and cornea. The Nidek OPD III acts as both a wavefront aberrometer and a corneal topographer.
Wavefront aberrometry gives an unprecedented assessment of visual acuity and quality of vision. Our machine is able to detect higher order aberrations in the optical pathway between the cornea and the retina. This allows for precise quantification of refractive error and aids in determination of optimal corrective eyewear.
Corneal topography provides intuitive elevation maps and numerical data for the corneal surface. This allows for enhanced detection of corneal pathology such as keratoconus and pellucid marginal degeneration. Serial topography is key in determining if such conditions are progressing over time which may indicate the need for surgical intervention such as corneal collagen crosslinking (C3-R) with riboflavin.
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 a 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).
Mediworks S391L Firefly WDR Digital Anterior Segment and Meibography Slit Lamp
The Mediworks S390L Firefly is premier tower style slit lamp built with exceptional quality at an affordable price. Featuring built-in digital imaging controls, crisp optics ranging from 6x-40x magnification (6x, 10x, 16x, 25x, 40x) on a 5 step drum, LED illumination, a full complement of filters, fixed and variable slit length/apertures and the ability to facilitate accessories such as a Goldmann tonometers.
The design is widely inspired off that of a Firefly. This smart design saves space for doctors compared to other bulky DSLR camera systems attached with an aftermarket beamsplitter. The Firefly is ready to use right out of the box with a handful of preset camera parameters so the user does not need to adjust settings before use.
