Binocular Vision
We have a history of collaboration with Psychology in this field. A clinical test for assessing distance stereoacuity, the FD2, was designed here. It is now used worldwide and its use in intermittent exotropias well documented. Research into different visual stimuli to investigate stereopsis continues.
Many aspects of stereopsis and clinical testing have been investigated including the response to different stimuli, the effect of vergence adaptation and anisometropia. Further work will explore how the presence of nystagmus impacts on stereoacuity.
Collaboration with clinicians at the Royal Hallamshire Hospital have investigated the effectiveness of tests commonly used for control of strabismus and how occlusion therapy in intermittent exotropia can improve control.
Previous projects on the role of tonic accommodation and monocular cues in stereopsis has been the catalyst for the investigation of the integration of stereo, motion, texture and size cues in the perception of depth in an interactive virtual environment.
Our understanding of ocular dominance is limited and investigating sensory dominance is providing further evidence of the response under different viewing conditions and how dominance can be manipulated.
