Electroretinographic evidence of miosis-induced peripheral ring scotoma.
The results of a previous series of experiments in rabbits suggested that under scotopic conditions miosis elevates the electroretinogram (ERG) threshold by casting a peripheral ring scotoma. In the present work similar experiments failed to show any change in the ERG under photopic conditions.
