Precision Therapy for Inherited Retinal Disease: At the Forefront of Genomic Medicine.

Inherited retinal diseases (IRDs) represent a diverse array of conditions characterized by dysfunction or loss of 1 or more retinal cell types. Next-generation sequencing has enabled rapid and relatively inexpensive genotyping, with more than 250 genes identified as responsible for IRDs. This expansion in molecular diagnostic accuracy, in combination with the retina's relative accessibility and immune privilege, has fostered the development of precision therapies to treat these myriad conditions. Novel techniques are being used in early trials. Precision molecular therapies for IRDs hold great promise as diagnostic and treatment strategies continue to expand.
