Bradyopsia, also known as prolonged electroretinal response suppression, is related to prolonged electroretinal response suppression 1 and pathologic nystagmus. An important gene associated with Bradyopsia is RGS9BP (Regulator Of G Protein Signaling 9 Binding Protein), and among its related pathways/superpathways are Signal Transduction and GPCR downstream signalling. Affiliated tissues include eye and retina, and related phenotypes are visual impairment and photophobia
