Objectives

Narrative objectives1

We have previously found that L-dopa medication increases blink frequency in patients with advanced PD using an ophthalmic device and that plasma L-dopa concentration correlates with blink frequency ("An uncontrolled, open-label, exploratory clinical study on the association analysis of ocular information using an ophthalmic device in patients with PD (UMIN:000044246)"). An uncontrolled, open-label, exploratory clinical study of the association analysis of ocular information using an ophthalmic device in patients with PD (UMIN:000044246)"). In this previous study, the MDS-UPDRS Part III score of PD motor symptoms, the ON/OFF score of the patient symptom diary, and the L-dopa blood concentration showed similar trends to the blink frequency. Furthermore, by extracting various parameters such as blink duration and confidence from the blink information and applying machine learning, we constructed a model to estimate clinical symptoms at the same point in time from 3 minutes of blink data. UPDRS Part III score in real time.
Based on these results, we believe that "blinking eyes" can be a simple, non-invasive biomarker that reflects PD symptoms in real time, and we decided to validate this model in a multicenter study with a larger number of patients.

During an outpatient visit or while hospitalized, the patient will record spontaneous blinks while wearing an eyeglass-type device and watching a video for 15 minutes while taking his/her usual therapeutic medications. Clinical symptoms of Parkinson's disease and other symptoms will be evaluated before and after wearing that eyeglass device. We examine whether the blink can be analyzed to predict Parkinson's disease motor symptom scores.
