VANCOUVER, British Columbia — Researchers saw changes in oligomeric alpha-synuclein in both basal and reflex tears in patients with Parkinson’s disease, according to a study presented here at the Association for Research in Vision and Ophthalmology meeting.

“Changes are more pronounced and have a stronger increase ... when we measure in reflex tears,” principal investigator Sarah F. Hamm-Alvarez, PhD, told Healio.com/OSN.
