Microbiome and Inherited Retinal Degenerations

Area of Science:

• Ophthalmology
• Microbiology
• Genetics

Background:

• Inherited retinal degenerations (IRDs) are progressive, genetically diverse eye diseases causing irreversible vision loss.
• While IRD genetics are increasingly understood, exact pathogenic mechanisms remain unclear.
• Gut microbiome alterations are implicated in various ocular and systemic diseases, including autoimmune conditions.

Purpose of the Study:

• To review the current understanding of the gut microbiome's role in inherited retinal degenerations.
• To explore the association between gut microbiome changes and IRD pathogenesis.
• To examine the contribution of the gut microbiome to the inflammatory aspects of IRDs.

Main Methods:

• Literature review of studies on gut microbiome and inherited retinal degenerations.
• Analysis of evidence linking gut dysbiosis to ocular inflammation and autoimmune processes.
• Synthesis of current knowledge on the pathophysiology of IRDs.

Main Results:

• The gut microbiome influences susceptibility to autoimmune eye diseases like experimental autoimmune uveitis.
• Evidence suggests inflammatory and autoimmune components are involved in IRD pathogenesis.
• Gut microbiome alterations may contribute to the inflammatory underpinnings of IRDs.

Conclusions:

• The gut microbiome is a potential factor in the development and progression of inherited retinal degenerations.
• Further research into the gut-retina axis may reveal novel therapeutic targets for IRDs.
• Understanding the gut microbiome's influence is crucial for unraveling IRD pathophysiology.
