RODRIGUES, Márcio Penha Morterá y DANTAS, Adalmir Morterá. Evaluation of the b-wave electroretinogram in Athene cunicularia. Rev. bras.oftalmol. [online]. 2008, vol.67, n.6, pp.287-291. ISSN 0034-7280. http://dx.doi.org/10.1590/S0034-72802008000600004.
PURPOSE: To evaluate b-wave of the electroretinogram of the burrowing owl (Athene cunicularia), differentiating the retinal electric reply in photopic and scotopic environment. METHODS: Transversal observational study was carried through, with the register of the full field electroretinogram of fourteen eyes; seven were stimulated in photopic environment and seven in scotopic environment using with white light according to the ISCEV protocol. RESULTS: The electrical responses of the retina of the species studied showed no statistically significant difference for the applied spectrum of white light in both scotopic photopic environments. CONCLUSION: The data allow us, therefore, to infer that the perception of the Athene cunicularia of the white color is the same one, in clear and dark environments, what it can be responsible for the adaptive capacity of the species in their natural habitat.
