Abstract:

Timira is a classical Ayurvedic ocular disorder described under Drishtigata Rogas, characterized primarily by progressive
diminution of vision. Ancient texts delineate its pathogenesis based on Dosha vitiation affecting successive ocular
structures (Patalas), eventually leading to severe visual impairment if untreated. In modern ophthalmology, refractive
errors—including myopia, hypermetropia, and astigmatism—represent the most common causes of visual impairment
globally, particularly among children and young adults. This review aims to critically analyze the concept of Timira and
explore its possible correlation with refractive errors from a contemporary biomedical perspective. A structured literature
review was conducted using classical Ayurvedic texts (Charaka Samhita, Sushruta Samhita, Ashtanga Hridaya) and
modern databases such as PubMed, Scopus, and Web of Science. The analysis suggests that early stages of Timira,
particularly involvement of the first and second Patalas, share clinical similarities with refractive errors, including blurred
vision, difficulty in distant or near vision, and visual distortion. However, Timira is a broader pathological entity
encompassing progressive degenerative changes, whereas refractive errors are primarily optical abnormalities. Ayurvedic management focuses on Dosha balancing, Rasayana therapy, and local ocular procedures such as Tarpana and Anjana,
while modern treatment relies on optical correction and refractive surgery. Although conceptual overlaps exist, direct
equivalence remains limited. Integrative research is necessary to validate these correlations and explore complementary
therapeutic strategies.
