Defects, Blemishes and Abnormalities of the Horse's Eye. 321 



4th. The sunken eye. This has been already referred to 

 under the small eye. The eyelids are usually flaccid, the upper " 

 being drawn in by its levator so as to form an angle, and the 

 edges of the orbit are somewhat prominent. It is seen in old, 

 worn out animals, which have lost the pads of fat in the depth 

 of the orbit, and more commonly in animals that have suffered 

 several attacks of recurrent opthalmia. 



5th. The projecting eye. In this case the lids are unduly 

 contracted and the eye protrudes between them so as to show a 

 large amount of sclerotic around the transparent cornea. This 

 may be due to nervous strain and suffering hut, however pro- 

 duced it is decidedly unsightly and objectionable. 



6th. The weeping eye. This is always a condition of disease. 

 It may be due to irritant gases, or solid particles, to inturned 

 cilia, everted lids, conjunctivitis or a variety of other conditions. 

 A careful examination may show whether it is only a transient 

 and remediable fault of a good eye or a permanent and irremedi- 

 able defect. 



7th. The blear eye. With swelling and scabbing of the edges 

 of the lids and Meibonian glands, and congestion of the adjacent 

 conjunctiva, there is usually some blurring of the surface of the 

 transparent cornea. The trouble is mostly chrofaic and consti- 

 tutes a serious objection. 



8th. The watch eye. In this, as in the albino, there is a 

 lack of pigment, so that the iris and sclerotic are white or bluish 

 white in part or in whole. vSuch an eye may be good and dura- 

 ble, but not beautiful nor attractive. - 



9th. Blindness of one or both eyes. In all such cases the 

 pupil remains fixed and immovable, showing no accommodation 

 to light and darkness, and there is a lack of prompt respon- 

 siveness on the part of the eye to sounds and objects. In amau- 

 rosis, glaucoma and cataract especially, the pupil remains widely 

 open, and alert movements of the ears are employed to make up 

 for the lack of sight. The condition often comes from internal 

 ophthalmia, such as the recurrent form, and is associated with 

 atrophy of the bulb. 



loth. Eyes of unequal size. This usually implies serious 

 disease in one, not infrequently recurring ophthalmia.
