    Robotic Oculomotor Simulator

    Current eye tracking and calibration algorithms do not accommodate eccentric viewing and the capacity for accurate eye tracking is difficult to assess in individuals with central visual field loss, and few studies of naturalistic oculomotor behavior exist. To address this problem, we are developing a binocular robotic model of the human eyes that can simulate fixation and eye movements with an eccentric preferred retinal locus in one or both eyes and allow for precise assessment of eye tracking performance of head mounted computer vision-based eye tracking systems.

    Mechanisms of Photophobia in Mild Traumatic Brain Injury in Human Subjects: Therapeutic Implications

    The purpose of this grant is to identify the mechanisms responsible for generating photophobia in patients who have suffered mild traumatic brain injury (mTBI). Currently, estimates indicate that this painful condition persists in about 60% of those who suffered from blast-related traumatic brain injury and 30% of those who suffered non-blast-related concussive injuries.

    SL-CN: Harnessing the Power of Drawing for the Enhancement of Learning across Levels of Vision Function

    This Science of Learning Collaborative Network brings together researchers and experts from the Smith-Kettlewell Eye Research Institute, University of Bamberg (Germany), Columbia University and Emory University to investigate how the visual art of drawing can enhance learning. Underlying learning principles and neural mechanisms will be considered, and how these can be harnessed for real-life learning enhancement. Though humans have been drawing for at least 30,000 years, little is understood about brain processes involved in this activity.

    Stereopsis in Macular Degeneration

    Macular degeneration affects the central retina, often causing asymmetrical damage to the two eyes. How does this asymmetrical loss affect stereopsis — the percept of depth generated by the small separation of image features in the two eyes?

    Spectral ERG analysis of hypersensitivity to light in traumatic brain injury

    The purpose of this research study is to use the spectral electroretinogram (ERG) to deteremine how the retinal mechanisms of sufferers from abnormal light sensitivity due to head injury differ from those without abnormal light sensitivity.
