Abstract Purposes: To determine whether a new hand-held, portable ERG device, RETeval CompleteTM, can be used to evaluate retinal function of children.

Patients and methods: Three children from three families (Case 1; 8-year-old boy, Case 2; 8-year-old boy and Case 3; 9-year-old girl) who were intolerant to contact lens electrodes were recruited. One of their family members had been already diagnosed as hereditary retinal diseases, i.e., complete congenital stationary night blindness (cCSNB, Case 1), X-linked retinoschisis (XLRL, Case 2) and retinitis pigmentosa (RP, Case 3), by conventional ERG measurement with contact-lens electrodes. The light- and dark-adapted ERGs were recorded with the RETevalTM under dilated conditions with skin electrodes, and responses were compared with 10 eyes of 10 healthy controls.

Results: The results of controls by the RETevalTM were compatible to those by the conventional ERG method. In the three cases, the results of RETevalTM showed characteristic features of cCSNB, XLRS and RP, respectively.

Conclusions: The RETevalTM has a potential to evaluate retinal function under both scotopic and photopic conditions with dilated pupils, especially for patients who are intolerant to contact lens electrodes.
