My current research is in the areas of normal and abnormal oculomotor systems, which includes both versional and vergence eye movements, as well as accommodation. This broadly includes both experimental aspects and bioengineering-based system modeling/computer simulations. The accommodation studies are in the areas of myopia, where we have developed a retinal-based biochemical model of refractive error development related to retinal defocus and nearwork, and the human depth-of focus, where we have studied blur detection in the near retinal periphery and have correlated it with retinal neuroanatomy/neurophysiology, optical aberrations and visual attention. The studies on eye movements are in the areas of nystagmus, where we are investigating the effectiveness of various forms of feedback (visual, auditory and/or proprioceptive) in the development of new treatment paradigms and devices for both adults and very young children, and in acquired brain injury, where we are investigating the use of visual and auditory treatment modalities to improve reading eye movements and reading ability with inferences regarding possible sites of residual neural plasticity; this will be followed in the future with a direct neurological assessment using brain-imaging techniques.
