Topcon Optical Coherence Tomography and Digital Retinal Photography
*Optical Coherence Tomography (or OCT) is a painless technique of imaging cross-sectional layers of ocular structures to enable analysis of the health of your eyes. Three-dimensional images can be produced highlighting the shape of the structures at the back of your eyes. This can aid in the diagnosis of eye diseases such as Glaucoma, Macular Degeneration, Diabetic Retinopathy, Retinal Detachment, and many other conditions which may affect the back of your eyes. Similarly, the OCT can also be used to assess the front structures of the eyes, including the cornea, iris and lens of the eye. This is useful for assessing risk factors for varying forms of glaucoma, and for measuring the thickness of the cornea.
*Digital Retinal Photography makes use of a special digital camera which photographs the Fundus at the back of your eyes. This records the appearance of your Optic Nerves, Maculas and Retinas. It also takes a record of the tiny blood vessels at the back of your eyes, which may be affected in conditions such as Cholesterol, Hypertension and Diabetes.
*OCT and Retinal Photography are usually performed at the same time.
Medmont Visual Field Examination
*Computerised Visual Field Examination (or Perimetry) is used to check your Peripheral Field of Vision. This is important in the detection of certain ocular and neurological conditions, such as Glaucoma, Retinitis Pigmentosa, Stroke, and certain types of Brain Tumours. It is also used to monitor these conditions, and it is particularly commonly used to give regular assessments of the progression of Glaucoma.
Oculus Keratograph and Dry Eye Assessment
*The Keratograph is used to assess the efficiency of the tears to maintain a healthy level of moisture to the Ocular Surface of your eyes. This device measures several functions of the tear layers some of which include: Tear Film Break-Up Time, Tear Volume, Lipid Function, and Infrared assessment of the Meibomian Glands. This helps in determining whether Dry Eye Syndrome is present, and if so, whether it is due to aqueous deficiency, evaporative causes, or a combination of both of these. With this information it is then possible to determine what type of treatment is most suitable for your Dry Eye symptoms.
E-Eye IPL Dry Eye Treatment
*Intense Pulsed Light (or IPL) involves the use of high intensity pulses of light to the Meibomian Glands. These glands are located in the upper and lower eyelids next to the eyelashes. These glands are meant to produce lipids (or oily secretions) into the tear film to prevent evaporation of the tears during normal use of your eyes. When these glands do not function correctly it has been shown that the IPL stimulates an improvement in the production of these lipids to enable the eyes to have better lubrication and less evaporation of the tears. At least three treatments are required over a six week period, followed by subsequent treatments if necessary. This gives noticeable relief to patients suffering from the annoying condition called Dry Eye Syndrome.
Blephex Blepharitis Treatment
*Blepharitis is a condition where inflammation of the Margins of the Eyelids causes a build up of crusty discharge around the Eyelids and Eyelashes. This causes irritation and poor vision to sufferers of this condition. The Blephex instrument involves the use of a motorised rotating pad which is rubbed across the inflamed eyelid margin and eyelashes. This cleans the area with the use of a medicated solution to cleanse the eyelids and eyelashes, thus relieving the symptoms of gritty sticky eyes, which are often worse in the mornings on awakening.
Digital Tracing of Spectacle Frames for Accurate Lens Fitting
*The Tracer is used to determine the exact size and shape of a spectacle lens which is to be prescribed to fit into the spectacle frames you have selected. This digital information is then saved onto the computer system, and it is then sent via the internet to our specialised lens manufacturer suppliers to get a perfect fit of your new lenses into your new frame. This eliminates the need for grinding of the lenses in our spectacles fitting workshop, although we can still do custom fits if required to do so. This speeds up the process of getting your new glasses as quickly as possible, along with more accurate lens fitting and a better quality product.
*Slitlamp Biomicroscopy involves looking at the front structures of your eye to check the health of structures such as the Cornea, Iris, Conjunctiva, Lens and Eyelids. This aids in the detection and treatment of many eye conditions such as Cataracts, Conjunctivitis, Uveitis, Dry Eye Syndrome, Blepharitis, and Corneal Trauma and Disease. This instrument is invaluable to aid in treatment of these conditions with the use of medications such as eye drops and ointments.
*Corneal Topography involves mapping the front surface of your eye – the Cornea, providing a 3-D image of this structure. This is important for checking conditions such as Astigmatism, and Keratoconus. This is also used for the fitting of hard and soft contact lenses for general use and in the specialised technique of Ortho-Keratology where rigid contact lenses are worn while you sleep to re-shape your eyes to correct your vision overnight.
