Raktapitta , caused by vitiation & combination of pitta & rakta , is manifested as bleeding through all the external orifices of body. Urdhwaga especially netragata raktapitta is always taken as subconjunctival haemorrhage. But , in fact it is complex disorders associated with increased blood stasis & arteriosclerotic changes in ocular blood vessels.
