Eye Movement Laboratory
Eye movements redirect our eyes to view objects of interest in our environment. Assessing where and how fast our eyes move can be done with high precision using eye trackers. This might be necessary in cases where patients have suffered a stroke or in individuals with nystagmus.
Depending upon the situation, more information can be acquired with eye movement recordings than by observation alone. Various research projects have been undertaken through the Eye Movement Laboratory. These have included an analysis of the effects of alcohol on eye movement control and investigation of how people with congenital nystagmus view the world. Work has also been undertaken for industry.
In the Eye Movement Laboratory, ocular recordings are undertaken with the aid of a non-invasive infrared eye tracker. Such recordings may provide information about the latency, accuracy and velocity (or speed) of ocular control. Alternatively, information about where gaze is directed when viewing different stimuli, such as a face versus a landscape scene, can be extracted. All of this information provides insight into the control of the brain over the ocular positioning.
The information gained from the recordings in individuals with nystagmus can diagnose its type (i.e., congenital or acquired) and identify if a particular treatment option, particularly eye muscle surgery, would benefit the individual.
If you have been referred for an assessment of your ocular control, please contact one of the Orthoptists below to make an appointment time. Please note that Dr Linda Malesic should be contacted for nystagmus recordings.
