Microbial Dynamics in Ophthalmic Health: Exploring the Interplay between Human Microbiota and Glaucoma Pathogenesis

Area of Science:

• Microbiology
• Neuroscience
• Ophthalmology

Background:

• The human microbiome is vital for host homeostasis, immune system maturation, and pathogen inhibition.
• A healthy ocular microbiota prevents infections by acting as a barrier against pathogens.
• Microbiota dysbiosis is increasingly linked to neurodegenerative diseases, with preliminary evidence in glaucoma patients.

Purpose of the Study:

• To review the influence of oral and gut microbiota composition on neurodegenerative diseases.
• To explore the potential role of microbiota dysbiosis in glaucoma pathogenesis.
• To highlight the unknown mechanisms connecting the human microbiome and glaucoma.

Main Methods:

• Literature review of studies on human microbiota and neurodegenerative diseases.
• Analysis of research linking ocular, oral, and gut microbiota to glaucoma.
• Synthesis of current knowledge on microbiome-host interactions in neurological health.

Main Results:

• Significant differences in ocular, oral, and gut microbiota exist between glaucoma patients and healthy individuals.
• Dysbiosis in the oral and gut microbiota is suggested to play a role in neurodegeneration.
• Limited evidence currently exists, and mechanisms remain largely unelucidated.

Conclusions:

• The human microbiome, particularly oral and gut microbiota, may influence neurodegenerative disease development.
• Further research is needed to elucidate the specific mechanisms linking microbiota dysbiosis to glaucoma.
• Understanding these connections could offer novel therapeutic targets for glaucoma and other neurodegenerative conditions.
