Netra-nádi and are classified into four different groups, the different symptoms of which will be described presently. A suppuration (D. R. swelling) in any of the unions (Sandhi) of the eye marked by a discharge of pus is called Puyá-sráva. This is due to the concerted action of the Doshas (Kapha, Pitta and blood). The secretion of slimy, white and thick muco-purulent discharges marked by the absence of pain *[1] is called Śleshmá-sráva.

A swelling possessed of the preceding features and occurring at the very same joining is called Alaji (Keratitis)‡[3] .

Parasites of different forms in such a case are found to infest the regions where the inner lining of the Vartma-

- ↑ † According to Mâdhava's reading thinness and warmness are not essential.
- ↑ ‡ The difference between a case of Parvani and that of Alaji is that the swelling in a case of Parvani is smaller, and that in the Alaji is larger.
