From among the "Ashtangas", the eight ‘Angas’ (part) dealt by the Ayurveda, Urdhwanga Chikitsa is most important, since it deals with eye, ear, nose, face and head. 'Uthamanga' (prime part) of human body is said to be the Head. In Shalakya Thantra there are also descriptions of about 76 eye diseases, 28 ear diseases, 31 nose diseases. And many of the illness affecting
human eye still have no proper remedies even in modern medicine like Retinitis Pigmentosa.
But certain remedial measures mentioned in ancient Ayurvedic Grandhas, particularly in Thaliyolas (palm leaves), have unfortunately not yet been completely examined.
