Can anything be done for my color-blind child?
A study published in Brain used gene therapy to partly restore the function of the retina’s cone receptors in two children who were born completely color blind.
According to lead author Tessa M. Dekker, PhD, MSc, of the UCL Institute of Ophthalmology and UCL Psychology & Language Sciences, this study "is the first to directly confirm widespread speculation that gene therapy offered to children and adolescents can successfully activate the dormant cone photoreceptor pathways and evoke visual signals never previously experienced by these patients.” (via)
