Electrical Indices of Rod Dysfunction

Résumé

Patients presenting with night time vision diffi­culties and a family history of retinitis pigmentosa require special testing procedures even in the absence of typical functional deficits or ophthalmo­scopically visible retinal disease. The authors discuss various theoretical aspects of electroretino­graphy and their practical clinical applications in objectively identifying the physiological defect occurring in retinitis pigmentosa.
