About Us

QEDIC (Queensland Electro-Diagnostic & Imaging Centre) is a tertiary referral clinic providing a unique visual diagnostic service for all of Queensland and beyond.

QEDIC offers a series of tests performed to international standards which permit the investigation of visual disorders and enable suitable management of patients who have retinal or optic nerve disorders. These tests permit the discovery of retinal function, dissecting the retina layer-by-layer, cell-by-cell. They are non-invasive and provide information regarding the eye and visual function not otherwise available. These tests are an important addition to normal eye investigation and examination, and help clinicians distinguish between different eye disorders that may have the same symptoms.

QEDIC has a strong commitment to research and in this respect collaborates closely with clinicians and researchers at the Queensland Eye Institute, as well as with researchers at other electro-diagnostic centres within Australia and overseas.



In the 1970’s, Dr Denis Stark pioneered visual electrophysiology in Queensland, resulting in the establishment of what was to become the Visual Electro-Diagnostic Clinic (VEDC) in 2006 at Mt. Gravatt in Brisbane. During these years, Dr. Stark built up a strong referral base from Queensland, northern New South Wales, and the Pacific Islands.

From February 1, 2014, VEDC was acquired by the Queensland Eye Institute with the aim of growing both the clinical diagnostic and research capabilities of the Clinic.


Tests Provided

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.

All tests are carried out in accordance to international standards established by the International Society for Clinical Electrophysiology of Vision (Iwww.iscev.org).
