Digital Retinal Imaging
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.
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.
High Definition SD-OCT
The iVue® spectral domain OCT is the most versatile system available today for RETINA, GLAUCOMA and ANTERIOR SEGMENT imaging. Manufactured by Optovue, iVue is a portable, affordable, easy-to-use and upgradable OCT.
iVue provides 5 micron resolution for excellent retinal imaging and analysis. Capabilities include 3D imaging, retinal mapping, RNFL and Ganglion Cell Analysis, cup-to-disk ratio, pachymetry mapping and angle measurements, as well as the largest clinically validated normative database available.The streamlined user interface, easy-to-read reports and small footprint enable efficient clinical use and patient throughput, while NetVue PRO software enables dynamic imaging and manipulation of data in examination lanes.
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 you are concentrating.A visual field test measures how much ‘side’ vision you have.

Each eye is tested separately and the entire test takes 15 minutes. Your optometrist may ask only for a driving licence visual field test, which takes about 5 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.
Normally the test is carried out by a computerized machine, called a Humphrey Frequency Doubling visual field. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a response button each time a stimulus is seen.
