Bridging concepts of drishti: Shalakya tantra and modern science

Introduction: Shalakya Tantra, a key aspect of traditional Indian medicine, focuses on the intricacies of human vision or 'drishti' in Ayurvedic literature. This ancient discipline offers a comprehensive exploration of 'Urdhvajatrugata' parts, encompassing the eyes, ears, nose, throat, and head, which modern research has yet to match in depth. The study of 'drishti' and its related concepts, such as 'mandala,' 'patala,' and 'sandhi,' reveals a profound understanding that warrants further exploration, particularly in contrast with contemporary findings. The Sushruta Samhita details 'Drishti' extensively, describing its anatomical and functional aspects, including its composition of 'Dravyas' (substances) and 'Mahabhutas' (elements), with a notable presence of 'Teja' or fire as 'Alochaka Pitta.' Aim and Objective: · To describe 'Drishti' from both Ayurvedic and modern perspectives. · To provide a detailed analysis of the various aspects of 'Drishti.' Materials and Methods: Materials include Ayurvedic scriptures (Sushruta Samhita, Charak Samhita, Bhela Samhita), modern textbooks, medical journals, and published research papers. The study is a review based on literature from authentic Ayurvedic sources and modern texts. Results and Discussion: The concept of 'Drishti' is analysed from anatomical and physiological viewpoints. Ayurvedic texts describe the eye as a layered entity with six junctions and thin membranes crucial for its function. Different interpretations of 'Drishti' include the retina, vision, pupil, and crystalline lens. Modern science aligns with these descriptions through detailed processes involving light refraction, image focusing, and neural processing. Conclusion: The study highlights the synergy between Ayurvedic and modern scientific perspectives on 'Drishti,' emphasizing the relevance of traditional wisdom in contemporary healthcare. Integrating these approaches offers a richer understanding of ocular health and underscores the potential for future research to enhance medical treatments and promote holistic well-being.
