We allow 30 minutes for a routine eye examination including Retinal Photography but 60 minutes for an appointment with OCT. This allows enough time for all the necessary tests to be done in a relaxed, unhurried manner, reducing any fear you might have of being rushed into the giving the "wrong" answer.
We ask at the start if you have any concerns about your eyes or vision so we can make sure that these are answered before the end of the test. Questions about your eye history, general health, work and/or hobbies help to put our findings into context and often lead us towards solutions for any problems. We explain what the different tests are for and what they involve as we go through them.
THE LETTER CHART
Our computerised chart has constantly changing letters, removing any concern that you might be remembering them rather than really reading them.
At Early and Edmonds Opticians a tonometry test is part of a regular eye examination. This test measures the pressure inside your eye, which is called intraocular pressure (IOP).
A tonometry test is used to check for glaucoma, an eye disease that can cause blindness by damaging the nerve in the back of the eye (optic nerve). Damage to the optic nerve may be caused by a buildup of fluid that does not drain properly out of the eye.
We use the applanation tonometry method (without air-puff), it is a very accurate method and uses a small probe to gently flatten part of your cornea to measure eye pressure and a microscope called a slit lamp to look at your eye. The pressure in your eye is measured by how much force is needed to flatten your cornea.
In this test you look at a central light and press a button whenever you see a little white dot flash.
At Early And Edmonds Opticians we use the Henson 7000 computerised field analyser which is particularly useful in detecting and monitoring glaucoma.
OCT - THE NEXT GENERATION OF EYE SCREENING
A few years ago, Retinal Photography was the best equipment available to screen the eye but now, Early And Edmonds has invested in the very latest OCT (Optical Coherence Tomography) scanning technology. This new advancement in eye screening uses state-of-the-art technology that enables us to take both a Retinal Photograph and a 3-Dimensional scan of the back of your eye that is non-invasive, painless, simple and fast.
This new technology brings a new and essential technique to scan your eyes and diagnose a number of common conditions that affect your sight including glaucoma, vitreous detachments and macular degeneration, which in their early stages may not be apparent in a routine examination or with Retinal Photography.
EYE TESTS FOR CHILDREN
All children in this country should have the opportunity to grow up with two good eyes. Studies have shown that during the first 45 years of life amblyopia (when vision doesn't develop because the eye doesn't receive a clear image or when there's a squint) is responsible for loss of vision in more people than all the other eye disease and trauma combined. Under 20 years of age, the incidence of amblyopia is ten times more frequent than all other eye diseases and trauma.
We encourage a relaxed and friendly atmosphere so that children can feel at home as they enter the practice and there is a selection of children's books in the waiting area.
Even in very young children, it's possible to do quite a few tests, such as retinoscopy, ophthalmoscopy, motility, pupil reactions and muscle balance tests. These are usually done with the child sitting on the parent's lap.
From the age of approximately three, it is possible to check the vision by showing letters and asking the child to point to corresponding letters on a card. Our letter chart has a selection of shapes and symbols that can be used instead of letters as well as pictures of animals and clowns that make the examination fun.
3-D goggles are used to test that stereo-vision is developing and other tests might include checks of colour vision and close focusing.
Other tests that might be required include testing eye movements (motility and convergence tests), pupil reactions and colour vision. Some other tests may also be required for those applying for certain jobs or careers, or who require certain licences.
This is a time to recap and to ensure that all your questions have been answered and any concerns addressed. For spectacle wearers, it's often helpful to have an initial discussion on the suitability of different spectacle lenses.
