Queensland Electro-Diagnostic & Imaging Centre

When visual function becomes impaired, electro-diagnostic tests can help pinpoint why

The Queensland Electro-Diagnostic & Imaging Centre (QEDIC) provides specialist visual tests to assist Doctors and Ophthalmologists in the diagnosis and treatment of eye conditions, particularly retinal or optic nerve disorders.

Importantly these tests are non-invasive and provide information on the eye and visual function not otherwise available.

The tests are an important addition to normal eye investigation and examinations, and help your Doctor or Ophthalmologist to distinguish between different eye disorders that may have the same symptoms.

The tests provide critical diagnostic information for conditions that can cause blindness such as retinal dystrophies, vascular diseases, opaque media/trauma, retrobulbar neuritis, unexplained visual loss, infancy vision problems, toxic and nutritional eye disease, suspected intracranial lesions and undetected cancers. These conditions are often not identified by conventional testing.

QEDIC is operated by The Queensland Eye Institute Foundation and no profit is made from operating this service. It is offered to help those in need with referrals received from all of the major Hospitals and Ophthalmologists in Queensland.

Tests provided by QEDIC include Multifocal Electroretinography, Electro-oculography, and various tests to measure Visual Evoked Potentials, including the ability to objectively measure visual acuity.

Unlike many other visual tests, these tests are objective, repeatable and non-invasive. Tests are provided to patients of all ages from new-born babies to the elderly.

QEDIC perform the following test procedures:

  • Electroretinogram (ERG)
  • Pattern ERG
  • Multifocal ERG
  • Electrooculogram
  • Visually Evoked Potential (VEP)
  • Albinism VEP
  • Visual Acuity (Sweep VEP)
  • Colour Vision – FM

QEDIC receives referrals not only locally in Brisbane but throughout Queensland and Northern New South Wales. All tests are carried out in accordance with international standards established by the International Society for Clinical Electrophysiology of Vision.
