Unveiling the Gut-Eye Axis: The Role of the Microbiome in Ocular Health

The gut microbiome (GM) is a diverse ecosystem of microorganisms that regulate digestion, immune function, and systemic inflammation. Recent research has uncovered its critical role in ocular health through the gut-eye axis, where microbial dysbiosis influences eye diseases such as uveitis, dry eye syndrome, and age-related macular degeneration (AMD). Disruptions in the gut microbiota lead to increased production of pro-inflammatory cytokines, altered immune responses, and compromised intestinal and ocular barriers, contributing to disease pathogenesis. Ayurveda, an ancient system of medicine, recognizes the gut’s influence on vision and emphasizes balanced digestion (Agni) for maintaining eye health. Ayurvedic treatments such as Virechana (purgation therapy) and Basti (medicated enema) are traditionally used to detoxify the body and restore microbial homeostasis. Herbal formulations, dietary modifications, and seasonal regimens further support gut integrity, reducing inflammation and enhancing ocular function. Scientific studies align with Ayurvedic principles, demonstrating that various therapies mentioned in ayurveda can positively influence gut microbiota and, consequently, ocular health. This review bridges the gap between modern microbiome research and Ayurvedic perspectives, proposing an integrative approach to managing ocular diseases through gut-targeted interventions. Understanding the gut-eye connection opens new avenues for preventive and therapeutic strategies, reinforcing the importance of holistic health in vision care.
