The enhanced S-cone syndrome (ESCS), a rare retinal degenerative disease often associated with NR2E3 mutation, is due to increased numbers of S-cones at the expense of other photoreceptors or miswiring distal to the photoreceptors. Paediatric ESCS and its differing clinical features (as opposed to adult ESCS) is the subject of this report.
