[Role and mechanism of autonomic nervous system regulation in primary glaucoma].

The regulation of blood flow in the human eye, aqueous humor production, and the outflow channels of aqueous humor are all controlled by the autonomic nervous system (ANS), encompassing both sympathetic and parasympathetic nerves. Patients with primary glaucoma often exhibit autonomic nervous system dysfunctions, which may exacerbate visual impairment. The homeostasis of the autonomic nervous system is influenced by circadian rhythms, physical exercise, emotional states, medications, and other factors. Previous studies have indicated that activities such as aerobic exercise, yoga breathing, and meditation can promote the restoration of autonomic nervous system balance, thereby reducing intraocular pressure. However, further evidence is required to substantiate the efficacy of ANS activity regulation as an effective adjunct therapy for primary glaucoma. This review examines the role and mechanisms of autonomic nervous system regulation in the context of primary glaucoma.
