Abstract

The analysis of the blood filling process is necessary to study the physiological characteristics of the blood circulation of the eye in normal and pathological conditions. In this paper, we studied the possibility of constructing a photoplethysmographic (PPG) diagnostic channel for assessing the hemodynamic characteristics of an eye and an eyelid. The main objective of this paper is to study the possibility of using PPG together with other diagnostic channels, as well as the study of motion artefacts when the PPG sensor is installed on the upper eyelid. The research group consisted of 6 volunteers without ophthalmologic disease. The red and infrared emission ranges for the PPG sensor were selected. Registration of PPG signals consisted of the following: PPG measurement in red and infrared light in the presence of artefacts in the horizontal plane, in the resting state, in the presence of artefacts in the vertical plane. It is shown that the infrared PPG channel has a greater signal-to-noise ratio (SNR) for both vertical and horizontal motion artefacts of the eye. As a result of this work, studies have shown that the infrared PPG signal is less affected by eye motion artefacts than red PPG. Moreover, the recorded signals in the conditions of vertical eyes movements have a lower SNR than in the conditions of horizontal eyes movements. The method of video PPG has shown better value of SNR by the diagnostics in the eyelid.
