“AYURVEDIC PERSPECTIVES ON KACHA AND LINGANASHA: A REVIEW OF TRADITIONAL INSIGHTS AND MODERN CORRELATIONS IN CATARACT AND BLINDNESS”
Introduction: Kacha and Linganasha are significant ocular disorders described in Ayurveda, often correlated with modern conditions of cataract and progressive blindness. Cataract remains the leading cause of reversible blindness worldwide, and Ayurveda’s insights into its pathogenesis and management provide a unique perspective that complements modern ophthalmology. Methods: A comprehensive literature review was performed using classical Ayurvedic texts (Sushruta Samhita, Charaka Samhita, Ashtanga Hridaya, etc.) alongside modern scientific databases (PubMed, Scopus, Web of Science, Google Scholar). Inclusion criteria involved texts and articles describing Ayurvedic concepts of Kacha and Linganasha, pharmacological studies on Ayurvedic formulations, and modern clinical or experimental research related to cataract prevention and management. Results: Ayurveda describes Kacha as a condition marked by progressive diminution of vision, with Linganasha representing the terminal stage of vision loss. Pathogenesis is primarily linked with vitiation of Vata and Kapha doshas obstructing visual pathways. Management strategies include internal medications (Ghrita, Rasayana), external therapies (Anjana, Tarpana, Putapaka), and surgical interventions in advanced cases. Modern parallels highlight antioxidant-rich herbal drugs such as Triphala, Yashtimadhu, and Shatavari showing experimental efficacy in delaying cataractogenesis by reducing oxidative stress and lens protein aggregation. Clinical studies on formulations like Triphala Ghrita and Jeevantyadi Ghrita have shown encouraging outcomes in early-stage cataract. Discussion: Ayurveda’s holistic approach emphasizes prevention and early intervention, while modern ophthalmology relies heavily on surgical correction. Integrative approaches using evidence-based Ayurvedic formulations may offer potential in delaying cataract progression and reducing blindness burden, though stronger clinical trials are needed. Conclusion: Kacha and Linganasha reflect Ayurvedic wisdom on ocular pathology, resonating with modern understanding of cataract and blindness. Strengthening cross-disciplinary research can pave the way for integrative therapeutics in ophthalmology.
