Summary

Amyotrophic Lateral Sclerosis (ALS) is the most common neurodegenerative disease affecting the motor neuron. Currently, there is no diagnostic test and no examination that can predict the evolution of this pathology. The search for diagnostic and prognostic biomarkers is therefore essential for a better understanding of the pathophysiology of ALS, which remains poorly understood, and also for better clinical management. The ocular surface, made up of liquid elements, tears, and cells, is an accessible anatomical-physiological entity that has demonstrated its usefulness in the identification of biomarkers in neurodegenerative diseases such as Parkinson's or Alzheimer's. To date, no study has explored the ocular surface as a biomarker in ALS
