On clinical observation, animal was emaciated with uncoordinated gait but the reflexes were found to be normal and exhibited progressive weakness upon exercise. On neurological examination, absence of withdrawal and deep pain reflex along with ptosis of both the eyelids, sluggish menace reflex and extra ocular palsies were noticed. Contrast radiography revealed megaesophagus. On biochemical analysis hyperproteinemia and hyperglobulinemia were observed. Based on these clinical observations and radiography, the case was confirmed as Ocular form of Myasthenia Gravis. The animal was treated with Inj.
