Visual disorders in ancient Indian science (interpretative study).

Sushruta classified and mentioned visual disorders in his classical text of 'Sushruta Samhita' under 76 eye diseases and also classified structural and treatment wise. Many authorities of the subject have praised Sushruta in their works and regarded him as a pioneer of ophthalmology. The saying 'nayanam pradhanam' shows that, without it there is no correspondence with external world. Sushruta showed a special interest in 'Drushtigata Rogas' and described thirteen such diseases. The visual disorders described in ancient Indian medical science by Sushruta are enlightened and presented in this paper analytically, diagramatically with the help of modern ophthalmology.
