Measurement of fundus pulsations in diabetic retinopathy based on laser interferometry

Comparison of non‐invasive methods for the assessment of haemodynamic drug effects in healthy male and female volunteers: sex differences in cardiovascular responsiveness.

“…The pulse-synchronous pulsations of the eye fundus were assessed by laser interferometry. The method has been described in detail by Schmetterer et al [9]. Briefly, the eye is illuminated by the beam of a single mode laser diode (X = 783 nm) along the optical axis.…”

“…A new non-invasive technique based on laser interferometry enables measurements of pulse-synchronous pulsations of the eye [8,9]. The analysis of these easily accessible pulsations may be particularly useful for the quantification of drug-induced changes in peripheral arterial blood flow due to vascular or cardiac drug effects.…”
