What is the main advantage of using dichoptic stimuli?
Dichoptic stimuli allow for a more reliable assessment of both monocular and binocular visual fields compared to traditional methods.
Who demonstrates the testing procedure?
Dr. Guler Arsal, a postdoctoral research associate at the Envision Research Institute, demonstrates the procedure.
What equipment is required for this assessment?
A 3D-ready monitor and wireless 3D active shutter glasses are required for the assessment.
How does the synchronization of shutter glasses work?
The shutter glasses must be synced with the monitor, ensuring no interference between the infrared transmitter and receiver.
Can this method be used for participants with different types of vision loss?
Yes, the method is designed to assess central visual field loss, which can vary among participants.
Is this method more straightforward than traditional techniques?
Yes, it provides a simpler and more straightforward approach than methods like using a haploscope.
