Sometimes, further tests may be required to further examine your eyes, these include:
Optical Coherence Tomography (OCT scanning)
This is a sophisticated scanning system that produces highly detailed images of the retina. It is often likened to an MRI or x-ray of the eye. This scan allows your optometrist to see detailed images of the retina (the inner most layer of the interior eye), enabling them to accurately detect, monitor and control changes to the retina.
This procedure is currently the only one that shows in-depth images of the eyes internal structures. Other procedures only show the surface of these structures. An OCT scan can detect the early signs of macular degeneration, glaucoma, detached retinas and other eye disorders. This procedure only takes minutes and the equipment never touches the eye, so there is no discomfort. Click on the link below for more information about the OCT scanner at MyOptical
Digital retinal photography
A more detailed inspection of the central area of the retina. This allows for a fast and more reliable diagnosis than has previously been possible. Retinal imaging helps us to diagnose, monitor and record many eye and health disorders. High resolution digital images of the retina are stored on a computer so that we can monitor any changes from one visit to the next.
Dilated Fundus Examination (DFE)
This is a diagnostic procedure that employs the use of eye drops to dilate or enlarge the pupil in order to obtain a better view of the internal surface of the eye (i.e. fundus). DFE has been found to be a more effective method for evaluation of internal ocular health than non-dilated examination.
Visual Field Analysis
Visual field analysis is a simple screening service which tests your peripheral vision. It is a test using an instrument with Frequency Doubling Technology. A series of light and dark bars will be displayed in the testing instrument in a manner which will stimulate certain eye cells and then measure the change of these cells and your response or ability to detect the light and dark bars in your visual field. In patients with glaucoma or diseases affecting the eye, the ability to detect the presence of stimuli in the periphery is diminished. Early screening of your visual field can detect a problem before you are consciously aware of it.
