BARRIENTOS CASTANO, Alberto et al. Reference values of the electroretinogram in the visual electrophysiology laboratory from the "Camilo Cienfuegos" Pigmentary Retinosis International Center. Rev Cubana Oftalmol [online]. 2011, vol.24, n.1, pp. 136-148. ISSN 0864-2176.

OBJECTIVE: To obtain the normal reference values of cone-rod standard electroretinogram in electrophysiology visual department of Camilo Cienfuegos Hospital. METHODS: 50 healthy individuals were studied and submitted to standard electroretinogram in electrophysiology visual department of "Camilo Cienfuegos" Hospital in Havana. We performed the electroretinogram according to the parameters of the standard committee of the International Society for Clinical Electrophysiology of Vision. The amplitud and implicit times of the main waves were measured in the five basic and an additional optional scotopic reponses. RESULTS: The five basic responses were obtained with similar morphology than other authors. In the rod response the «b» wave was between 72 and 89 ms with an amplitude between 128 and 380 µv. A combined response was obtained with "a" and "b" unfold wave. Scotopic oscillatory potentials with 4 and 5 components was obtained. The values and morphology of the waves in cones and flicker responses were similar that one reported by other authors. CONCLUSIONS: The normal reference values of the main clinical indicators of electroretinogram were obtained according to the standardized methodologies for our laboratory.
