Digital Imaging & Laser Retinal Scans
In his eye clinic in Ashland, Dr. Jonathan Noble uses cutting-edge digital imaging technology during his eye exams to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Digital imaging and other specialized testing can be very important in assisting your Optometrist to detect and measure any subtle changes in the health of your eyes. 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 the internal and external structures of your eyes
- Provides instant, direct imaging of the form, and function 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)
Dr. Noble is proud to introduce the latest cutting edge technology in retinal imaging, the 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. This allows your eye doctor to 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.
Visual Field Testing
A visual field test measures how much 'side' vision you have. It is a straightforward and painless test. 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 15-20 minutes.
Digital Slit Lamp Photography
A slit lamp is used to observe the external and internal structures of your eye under high magnification. It is like a microscope mounted sideways on a stand. A thin beam, or 'slit', of light can be adjusted to allow the light to "slice' through the structures of the eye under high magnification. A digital camera can then be used to take both still photos or video as appropriate.
