Seeking Participants for Research Study on Link Between Visual Function and Brain "Wiring" in CVI

Dr. Lotfi B. Merabet, O.D., Ph.D, MPH and the Laboratory for Visual Neuroplasticity at Massachusetts Eye and Ear Infirmary, Harvard Medical School are seeking participants for a research project.  They are interested in investigating how the brain develops and adapts in cortical/ cerebral visual impairment (CVI). Neuroscience research has revealed the remarkable ability of the brain to adapt and "re-wire" itself throughout a lifetime. This is the basis for compensatory behaviors observed in individuals living with blindness and visual impairment.

They are developing new approaches to assess visual function in CVI and using advanced brain scanning techniques such as magnetic resonance imaging (MRI) to help understand the neurological link between visual performance and brain structure and function in CVI.

Your participation will help them better understand how individuals with CVI see and interact with the world around them. They hope that this information will lead to a greater understanding of the structural and functional changes in the brain of individuals with CVI, as well as novel training strategies to aid with enhancing function.


Aged between 14 and 24 years and have visual impairment consistent with a diagnosis of cortical visual impairment (CVI)

Degree of participation depends on level of comfort of the individual, and may include:

  1. Visual function testing using virtual reality and eye tracking measures.
  2. MRI scanning sessions (training and scanning).

Participation in all phases of the study is not mandatory, and total compensation is dependent on degree of participation.
