A fundus, or retinal camera, is a specialized microscope with an attached camera designed to photograph the central retina, optic disc and macula.
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.
iCare Tonometers for easy, accurate and patient-friendly intra-ocular pressure measurement.
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. No specialized skills for its use the quick and painless measurement is barely noticed by the patient and and any anesthesia or inconvenient air puffs are not needed at all.
Electronic elevation, automatic alignment, focusing, printing, high-speed measurement, unequalled accuracy and all the other features that have made the Burton Automatic Refractors/Keratometer famous.
The accuracy of this combined instrument allows us to have a viable starting point in determining your glasses and contact lens prescription. The keratometer is also useful in determining the health and integrity of the cornea in conditions such as Keratoconus.
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 license 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.
