Northpoint Eyecare Diagnostic Tests

At Northpoint Eyecare we are happy to be able to provide sate-of-the-art diagnostic equipment that assists in the diagnosis, treatment planning and monitoring of your eye condition. Large screen monitors are provided in every consultation room to assist our doctors in communicating the results of all your tests, providing you with the information you require to understand your eye health and treatment.

Slit Lamp and Digital Photography

Included in your consultation, we are able to photograph the front of your eye as we examine you at our microscope called the ‘slit lamp’.

These images are projected on our large screens and recorded in your notes.

This and standard digital photography of your eyelids and any lesions surrounding your eyes is the best way of communicating with you about your condition and forms the best record possible.

Optical Coherence Tomography (OCT)

Optical Coherence Tomography or OCT is a test that uses light to create cross sectional images of the eye and has been a major advance in Ophthalmology in the last five years. The images from the latest Zeiss Cirrus OCT machine, include high resolution and 3D images of the retina, which aid in the treatment of numerous retinal diseases, most commonly Macular Degeneration and Diabetes.

This machine also can assist in the management of corneal and anterior segment disorders, with cross sectional images of the front third of the eye, as well as imaging the optic nerve with computerised analysis to aid in the detection and monitoring of Glaucoma.

The test is easy to perform, with your chin on the rest, looking into the lens of the machine. Unfortunately, despite being the gold standard for imaging the retina, this test does not currently have a rebate from Medicare.

Retinal Photography and Angiography

Photographs of the retina and optic nerve are a vital adjunct to clinical examination and not only serve to better inform you about your condition but provide the best way of recording and monitoring the back of your eyes.

In addition to this, the retinal camera can provide useful diagnostic information not visible with the naked eye. Angiography is a technique for imaging the blood vessels that supply the retina and other structures in the eye.

It is vital in the diagnosis and treatment of Macular degeneration, diabetes, and other retinal disorders. This test uses a fluorescent dye that is injected into a vein in your arm and a series of flash photographs are taken.

The results are automatically relayed into your consultation room to be interpreted and discussed with you. Most people have no problems with the injectable dye, however, there may be rare side effects. The risks and benefits of using this test will be discussed with you during your consultation.

Auto-fluorescence is another test to diagnose macular and optic nerve conditions that use a similar technique but without the dye.

These ancillary tests do attract additional charges and our staff will inform you of these, usually prior to your consultation.

Visual Field Test

This examination is performed on a machine called the Humphrey Visual Field Analyser. It is commonly referred to as a ‘field test’ and is most frequently used as a test of your peripheral vision. This can be affected by disorders of the eye, optic nerve and the pathways of the visual signals in your brain. The most common disorder affecting your peripheral vision is Glaucoma.

The test takes a few minutes, is simple to perform, and is easier on repeated examinations. It involves detection of a series of faint lights projected onto an evenly lit projection screen, in the shape of a bowl.

Your chin is placed on a chin rest and one of your eyes is covered with a patch to do so. One of our staff will guide you through the process and the test will be interpreted by your doctor in the consultation.

The field test has part of its cost rebated by Medicare.

Biometry

One of the most crucial aspects of cataract surgery is the prediction of the power of the Intra-ocular lens that is to be placed into the eye.

We have the latest versions of the gold standard, Zeiss IOL Master Biometry computer, and additional Ultrasound biometry when required for very dense cataracts.

This test is easy to perform and, unless using the ultrasound probe, involves no contact with the eye. With your chin on the chin rest, your technician will guide you through the process to ensure the most accurate measurements.

The lens choice will be discussed with you in the consultation to ensure the lens that most suits your needs is selected.

This test has part of its cost rebated my Medicare.

Refraction

This is the process of determining the ‘power error’ in your eye, or putting it another way, measuring your need for glasses to achieve the crispest vision possible. It is useful to compare this to the latest refraction performed by your optometrist, and you are asked to bring in this or your latest spectacles for your consultation.

Pachymetry

This test measures the thickness of your cornea, the clear front of your eye, and is either performed by the OCT machine or by a hand-held device after local anesthetic drops. This is useful in various diseases and degenerations of the cornea, and in predicting the progression of Glaucoma. There is no additional charge for this test.

Tonometry

This is a test of the pressure of your eye and will be performed by your doctor in the consultation or by one of our technicians prior to seeing the doctor. This painless test is most commonly used to monitor, and screen for Glaucoma, one of the leading causes of visual disability in Australia and the world.

Nasendoscopy

This is a technique of examining the nasal passages which is vital in both the diagnosis and surgical planning of tear duct disorders. An inhaled local anesthetic is given, followed by examination with a fibre-optic scope, and is well tolerated by the majority of people. There is a rebate for the costs by Medicare.
