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.
Digital Retinal Imaging, OCT Scans, and Angiography
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.
This also helps us to detect very early diabetic changes, along with concerning macular degeneration and glaucoma changes. This technology is also able to detect blood clotting disorders and blood flow issues to the brain. We continue to embrace new technologies that prevent unneeded vision loss.
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 a newer advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs the back of the eye. Our first OCT was acquired in 2007. It acquired 24,000 scans in one second. In February 2021, our third OCT was purchased and acquires 71,000 scans in one second. Our latest OCT has the ability to scan the blood vessels, the healthier the optic nerve and retina. Changes can be tracked over time.
A scanning laser is also 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 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 continuing to revolutionize 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 just a few minutes. Feel free to contact our office to inquire about an OCT at your next appointment.
A common misperception is that you see with your eyes. While your eyes actually do receive information the process of converting that information takes place in the brain. The Diopsys measures the strength and speed of electrical impulses that travel along the optic nerve between the eyes and the brain. This is a functional test, like the visual fields, but requires no patient response. This simple non-invasive test can lead to an even earlier diagnosis of glaucoma, macular degeneration, and diabetic retinopathy, 8 years sooner than OCT testing.
The Macular Pigment Optical Density test, or MPOD, is a useful tool in measuring your eye’s resistance to harmful blue light. Only 1% of eye doctor offices in the US have this insightful technology. Recent studies suggest that blue light, which is emitted from phones, digital screens, TVs, and even sunlight can cause damage to your eyes after prolonged exposure. If your score on the MPOD is low, you could be at higher risk for developing macular degeneration, especially if you have a family history.
Lower pigment scores have also been suggested as being a cause of increased glare, poor color vision and visual discomfort while using electronic devices. Recommendations are offered if scores are low, to improve your eye health. Yet another bonus, if your levels are high, it helps your brain work better!
The Ocular Response Analyzer, or ORA, is another one of the newest in cutting edge technology. The ORA uses air to determine the cornea’s hysteresis value. The cornea’s reaction to the air reflects the eye’s ability to protect the optic nerve from elevated eye pressure in conditions such as glaucoma and ocular hypertension. A low value indicates a higher chance of developing glaucoma, and if glaucoma develops, it progresses quicker than patients with higher values.
