Electroretinographic responses in patients with pulseless disease vary with head and body positions.
We examined bright-flash electroretinograms obtained in two Japanese women with pulseless disease. One 48-year-old woman (case 1) who has had the disease for 17 years showed no oscillatory potentials. When she sat and tilted her head to the right, a- and b-wave amplitudes diminished in the left eye. A second 48-year-old woman (case 2) who has had the disease for 10 years also demonstrated absent oscillatory potentials. When she sat and raised her chin, a- and b-wave amplitudes diminished in both eyes. These amplitudes were normal when the patients were in a supine position.
