Visual acuity and eye misalignment

The visual system is most responsive to the effects of insult and therapy during infancy. Early detection of visual acuity deficits and eye misalignment are, therefore, critical for the early diagnosis of preventable and/or treatable disorders that affect the eyes and the brain (e.g., amblyopia or lazy eye) and for monitoring responses to therapy. In this project we are developing objective, automated methodologies to assess visual acuity and eye alignment is infants.

Preferred Retinal Loci in patients with age-related macular degeneration

As an adaptive mechanism to the loss of central vision, patients with age related macular degeneration develop preferred retinal loci (PRL) in the eccentric retina. To maximize the benefits of PRL relocation training we develop methods to determine the absolute locations of the PRLs on the retina during binocular viewing.

Visual Field Testing

Visual field testing (perimetry) is of fundamental importance in the diagnosis of glaucoma. In this project we are developing a novel portable perimeter that can be used to screen for visual field defects in areas of the world that have limited access to expensive medical instrumentation.
