State of the Science for Neurorecovery/Neuroprotection as well as Visual Restoration Products for Retinal Degenerative Conditions
Event Date:

Abstract - Recent FDA cleared/approved devices and biologics as well as current clinical trials in these types of products which promised improved vision by neurorecovery or at least slowing of the vision loss progression with neuroprotection including:  1) Spark Therapeutics LUXTURNA gene therapy; and 2) Okuvision OkuStim Electrical Stimulation Therapy.  In addition, retinal and cortical prosthetics have promised restored vision by substituting mechanisms in the visual system.  This presentation will provide a review of the actual results of these types of products and the challenges that

 
 
Have You Heard About the Latest Products for people who have vision loss, FDA Cleared or Not?
Event Date:

Abstract - Dr. Ron Schuchard will review the recent research and development for products that are marketed for treatment of vision loss. This review draws from his experiences as a vision rehabilitation researcher and as a FDA senior staff member.  Attendees will also be encouraged to ask about treatments for vision loss that are of interest to them.

 
 
The Neural Representation of Perceived Color
Event Date:

Abstract - The distinction between stimulus chromaticity and perception of hue is critical for understanding color vision. A chromatic stimulus has spectral properties that characterize light entering the eye. The colors we experience, on the other hand, are perceptual constructs from neural processing within hierarchically organized cortical visual areas.

Beacon-based wayfinding for people with disabilities
Event Date:

Abstract - There are currently few options for navigational aids for people with disabilities, especially those who are blind, and visually impaired (BVI) in indoor spaces and around buildings. Indoor environments can be geographically large and intimidating such as grocery stores, airports, sports stadiums, large office buildings, and hotels. Thus, reading and following signs still remain the most common mechanism for providing and receiving wayfinding information in such spaces.

Perception of location computed outside the visual cortex
Event Date:

Abstract - Recent results indicate that an object’s visual location is constructed at a high level where, critically, an object’s motion is discounted to recover its current location. As a result, we sometimes see a target far from its actual location. One particular target, the double-drift stimulus, develops very large illusory shifts based on an integration time of well over a second suggesting the involvement of processes with the time course of short-term memory.
