Analysis of electroretinogram during systemic hypercapnia with intraretinal K(+)-microelectrodes in cats.

PURPOSE Systemic hypercapnia alters the intraretinal pH and metabolism and profoundly affects the vitreal electroretinogram (ERG). Using intraretinal K(+)-selective microelectrodes (ISMs), the authors examined the effects of systemic hypercapnia on ERG in the intact cat eye in vivo. METHODS Double-barreled K(+)-ISMs were used to record intraretinal, light… CONTINUE READING
