FUNDUS PHOTOGRAPHY
During the pre-tests, we keep track of the health inside the eye. Not only do we carefully examine your eye for changes on the eye nerve, fundus and macula – we keep photo records to help us see small changes which are early signs of glaucoma, macular degeneration and the effect of diseases like diabetes and high blood pressure. A Fundus camera is a camera with a specialized microscope, used for photographing the retina at the back of the eye.
This is part of our pre-testing procedure and every photo is saved to compare at each visit.
TONOMETRY
This is also known as the less popular “puff” test. It is however an important test in the evaluation of patients at risk of glaucoma. We are using a state of the art Tonometer and once aligned, it will complete the process automatically.
This procedure is used to evaluate the intra-ocular pressure – the pressure of the fluid inside the eye. The tonomer releases air over a range of pressures at your eye. At the same time, an infrared beam of light is shone off your cornea. When the cornea flattens out under the pressure of the air, the beam of light reflects at a different angle.
This test is also part of our pre-test procedure and is performed on all patients over the age of 9.
ANTERIOR PHOTOGRAPHY
Keeping an eye on the outside structures of your eyes. We examine the eye lids and eye orbit for threats like infections, cataracts, sun damage and other disease. Continuous follow up over time is monitored with photo records.
CORNEAL TOPOGRAPHY
The outer surface of the eye (cornea) largely contributes to the quality and health of the eye. Irregularities on the surface of the cornea can lead to blur, ghosting and hazy vision. With corneal topography studies we can detect, diagnose and monitor any abnormalities.
WAVEFRONT ANALYSIS
Good vision depends on a clear unobstructed path through optical the structures of the eye such as the cornea, eye lens and vitreous gel inside the eye. With wave front analysis we can identify and monitor aberrations causing glare, ghosting and blur especially during night driving.
OPTICAL COHERENCE TOMOGRAPHY (OCT)
A healthy central area inside the eye is critical for good small detail and colour in your vision. The macula (central vision) and optic nerve has very delicate cells and fibres which can cause serious vision loss when affected by disease. With OCT we scan these cells and fibres to detect early risk of disease and abnormality helping you to preserve and protect your sight.
VISUAL FIELD ANALYSIS
The eye nerve carries the message of vision to the brain where it is registered and interpreted. The path of the optic nerve travels through the brain and may be affected by conditions such as a stroke, head injury and other diseases such as multiple sclerosis, glaucoma and tumors amongst others. With visual field analysis we evaluate the function of the eye nerve and vision fibers in the brain to identify, diagnose and monitor your vision and health.
