We discuss the genetics, and clinical, psychophysical, electrophysiological and retinal imaging characteristics of cone and cone-rod dystrophies, focusing particularly on four of the most common disease-associated genes: GUCA1A, PRPH2, ABCA4 and RPGR. Additionally, we briefly review the current management of these disorders and the prospects for novel therapies. This evidence concerns the gene ABCA4 and cone-rod dystrophy.
