74 CATARACT. 



Amaurosis, G-utta Serena, 



This disease consists in entire or partial loss of 

 vision in consequence of paralysis of the optic nerve, 

 or interruption of its communication with the brain. 

 Injuries of the head, or ball of the eye, or some dis- 

 ease of the brain, are the usual causes. The horse 

 walks cautiously, head elevated, and ears move 

 quickly backwards and forwards, the eye has a 

 peculiar glassy appearance, and the pupil does not 

 dilate and contract when light is brought near or 

 removed from the eye. 



But little can be done for these cases. In the 

 earlier stages a dose of the Specific, A A, for IN- 

 FLAMMATION, may possibly arrest its progress, but 

 generally it is incurable in man or beast. 



Cataract. 



In consequence of injuries to the eye, blows, con- 

 tusions, etc., or as a consequence of severe and re- 

 peated inflammation, the crystalline lens becomes 

 opaque, so as to interfere with or altogether destroy 

 the sight. On examining the eye, deep in the pupil 

 a whitish, yellowish, or brownish body is discover- 

 able. Sometimes, especially in the commencement, 

 white streaks run from the centre outward, or the 

 whole chamber within the pupil looks dim and 

 whitish. 



Old Cataracts are incurable, but recent and form- 

 ing cases may be benefited by giving the Specific, 

 A A, for INFLAMMATION, and that for INJURIES, B 

 B, a dose (fifteen drops) every night alternately.
