Ophthalmology and Orthoptics Research
We carry out theoretical and applied research to understand many aspects of the visual system and improve patient management. Our work includes contributing to national guidelines, policies and care pathways.
Our research themes
We have strong multi-professional links within the University of Sheffield, other universities and external organisations. Our collaborators include psychologists, clinicians, medical physicist and others. Our research has been structured into four themes.
Accommodation & Physiological Optics
Research within the Unit has explored the optics of prisms and the effect of Fresnel prisms on uniocular and binocular visual acuity, contrast sensitivity and colour vision. The effects in mesopic and photopic conditions have been compared.
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.
