title: Influence of ultrasound on the electroretinogram and ultrastructure of the frog retina.
abstract: Electroretinography and electron microscopy were used to analyze frog retinas exposed to ultrasound. Toxic doses of ultrasound reduce the ERG b-wave amplitude and induce irreversible destructive changes in cells of all retinal layers. Therapeutic doses of ultrasound increased the b-deflection amplitude and led to slight mitochondrial edema and a decrease in the osmiophilicity of rods and cones. These studies support the view that therapeutic ultrasound doses increase the activity of photoreceptor cells.
