VETEEINARY OPHTHALMOLOGY. 31 



Blepharitis Ciliaris {Blepharitis Marginalia, Tinea 

 Tarsi, Ophthalmia Tarsi). — Earely met with in equine 

 patients, but wlienitis, it is long-lasting and very rebel- 

 lious. This may be merely a slight, scarcely perceptible 

 redness of the lid margin, while again it may, be very 

 severe — ulcerations, or thickened everted edges. 

 Caused by smoke, dust, cold winds, bright light and 

 too much of it. Lids are apt to be agglutinated. Edge 

 or margins scaly and scabby. Photophobia and lachry- 

 mation. Hair follicles may be destroyed and the cilia 

 fall out. The thickening and eversion of lids may 

 cause ectropium. 



Always assure yourself it is not the result of Phthe- 

 iriasis, for, if it is, ifc will be necessary to eradicate them 

 before attempting a cure of the Blepharitis. Use Merc. 

 Ting. Fungus growths in the hair follicles are also 

 said to cause this disease. Remove the, hairs by 

 epilation, and go on to cure. Lachrymal catarrh, and 

 particularly catarrh of the lachrymal sac, with stric- 

 ture of the duct; the tears, unable to get through into 

 the nose, flowing over the lids. Tears being retained, 

 inflammation ensues. In such cases open the cana- 

 liculus into the sac and give free passage for the tears, 

 then go on and treat as a simple case. It is very neces- 

 sary to observe cleanliness. Removal of scales and 

 &c?Cas.— without force. If can not get them away easily, 

 poultice the eyes for fifteen or twenty minutes. Then 

 proceed: Vaseline. Boric ac. and vaseline; gr.— xxx.
