Ptosis

(to's is.) [From Gr. pi pto, to fall.] (Med.) A dropping or falling of the upper eyelid, which arises from palsy of the third or motor oculi nerve. It may arise either from debility, in which case it maybe removed by tonics; or from congestion of the brain, when it is usually accompanied with giddine , headache, ., and should be treated by bleeding, purgatives, and low diet; or from organic disease of the brain, in which case remedies are of little use.
