Latest Digital Retinal Imaging Technology
Our Optometrists 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 are 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.
What is a Fundus Camera Camera?
A fundus, or retinal camera, A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula. Fundus photography documents the retina, The retina is the neurosensory tissue in our eyes which translates the optical images we see into the electrical impulses our brain understands.
The resulting photograph is a high resolution magnified image which can help to assess for eye conditions including glaucoma, diabetic retinopathy, macular degeneration, optic nerve disease, and many others. This picture also gives us a baseline to compare the state of your eye health in the future.
What is a Corneal Topographer?
The Corneal Topographer gives accurate mapping of the corneal curvature. The results are used to assist in contact lens fitting, refractive surgery, orthokeratology and general assessment of the cornea.
The Corneal Topographer provides superior accuracy of the corneal curvature. The results of this exam will lead to a more comfortable selection of contact lenses that are right for your lifestyle.
In addition to being a major part of a contact lens exam, a corneal topographer is used to assist in refractive surgery, orthokeratology and general assessment of the cornea.
Digital Retinal Imaging
Zeiss Cirrus 600 – State of the Art Retinal Scan
Digital Retinal Imaging 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 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.
We have just added the latest in retinal imaging technology, the Zeiss Cirrus 600 which combines digital retinal imaging with Optical Coherence Tomography (sort of like an MRI for the eye). With this we can manage macular degeneration, diabetes, glaucoma and many other eye conditions. We think its cool but eye doctors get excited about odd things.
Visual Field Testing
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.
Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 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 computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.
