Your eyes are extremely important and keeping them healthy is vital to good vision. There are several things you can do to help keep them healthy including regular comprehensive eye examinations. Performing these examinations ensures that any problems are caught early such as glaucoma, diabetic eye disease, age related macular degeneration and much more, in which most of these eye conditions will have no warning signs without a comprehensive eye examination to enable your eye care professional to have a good look at the back of your eyes.
OCT (Optical coherence tomography)
OCT is a non-invasive imaging test using light waves to take cross-section pictures of your retina, the light-sensitive tissue lining at the back of your eye.
With OCT, every layer of the retina can be seen, allowing your ophthalmologist to measure thickness of these layers which helps to diagnosis & provide treatment guidance for diseases such as glaucoma and others, such as age-related macular degeneration and/or diabetic eye disease.
Dilating eye drops may be used during an OCT examination in order to widen your pupil making it easier for your optometrist to examine the back of your eye. The OCT test takes between 5-10 minutes but if drops have been used to dilate your eyes, they may be light sensitive for hours after examination.
OCT is often used to diagnose optic nerve disorders as the exam can help determine changes to the fibers of the optic nerve, it is also useful in diagnosing the following eye conditions:
OCT is not suitable for anyone suffering from dense cataracts or significant bleeding of the vitreous.

Field screening tests are used to assess if you have any scotomas (blind spots) which can indicate certain diseases of the eye. If scotomas are present, the size and shape of the scotoma can help ascertain the presence and severity of eye disease in the eye, optic nerve and also visual structure of the brain. Eye and brain disorders that can cause peripheral vision loss and other visual field abnormalities include:

Colorimetry testing can determine what colour lenses are needed to help reduce the effects of these conditions, eyes can have colour sensitive cells in the visual vortex that become hyperexcitable when viewing print. By placing a colour in front of the eye it helps calm these cells and therefore limits the eyes excitability reducing the visual stress.
Our optometrists are trained to recognise and diagnose eye conditions such as dry eye syndrome, we will examine your eye to determine if this is the case, and also assess your eye to see if you have any other associated conditions and complications.
Once diagnosed with dry eye we can give you guidance on how to treat dry eye syndrome depending on the diagnosis for your dry eye, this may mean artificial tears, oily eye drops, eye ointments or anti-inflammatory treatments.
