    Higher Visual Function (HVF) in Individuals with Cerebral Visual Impairment (CVI)

    Cerebral visual impairment often affects higher level visual function (HVF); for example, spatial attention, motion perception, divided attention, etc.

    Human Echolocation

    What is echolocation? Sometimes, the surrounding world is too dark and silent for typical vision and hearing. This is true in deep caves, for example, or in murky water where little light penetrates.

    Integration and Segregation

    Traditionally, smooth pursuit research has explored how eye movements are generated to follow small, isolated targets that fit within the fovea. Objects in a natural scene, however, are often larger and extend to peripheral retina.

    Investigating Reading in Individuals with Cerebral Visual Impairment (CVI)

    There are many factors that can impair reading in CVI including, but not limited to, (i) increased crowding (ii) simultagnosia (i.e., difficulty processing two things at the same time) and (iii) abnormal eye movements.

  • Is Macular Degeneration just Macular?

    Diminished motion perception was used as indicator of early effects of eye diseases in the periphery of the visual field.

  • Low Vision Computer Access

    Dr. Deborah Gilden wants to ensure that people who work with low vision students, clients, or patients, or have a visually impaired friend or family member, know that many features built into the Windows OS, MS Office applications, and the Internet, often can serve as tools for low vision computer access.

    Micro-Perimetry by Scanning Laser Ophthalmoscope

    We developed software to make the retinal placement of stimuli during micro-perimetry by a scanning laser ophthalmoscope (SLO) independent of involuntary fixational eye movements.

    Motion as a Cue for Attention

    We investigated whether relative motion can serve as a cue for sustained attention.

    Motion Perception in Central Field Loss

    The project investigates motion perception in individuals with vision loss due to central retinal lesion, but who retain healthy peripheral retina.
