Amyotrophic Lateral Sclerosis
Conditions
Brief summary
Amyotrophic Lateral Sclerosis, or Charcot's disease, is a neurodegenerative disease affecting motor neurons. The disease affects between 5 and 10 people per 100,000 in the world, nearly 7,000 patients are affected in France. The only therapeutic treatment available to date in France is riluzole, which slows the progression of the disease. Amyotrophic Lateral Sclerosis is the first degenerative disease affecting motor neurons. However, recent evidence suggests that the impairment extends beyond motor neurons alone. Optical Coherence Tomography analyzes made it possible to highlight ophthalmologic damage in patients with Amyotrophic Lateral Sclerosis, in particular at the macula and papilla, although some results are contradictory. No angiographic Optical Coherence Tomography analysis has been performed to date in patients with Amyotrophic Lateral Sclerosis. However, in the hypothesis of microvascular involvement participating in the pathophysiology of neurodegeneration in Amyotrophic Lateral Sclerosis, these examinations could provide relevant clinical and pathophysiological data by studying the retinal microvascularization of patients with the disease.
