VETERINARY OPHTHALMOLOGY. 69 



inflammation of adjacent parts, etc. ; is one of the most 

 frequent diseases of the eye. It leads to vascularization, 

 cell proliferation and suppuration, each of these con- 

 ditions being more or less prominent according to the 

 kind of inflammation present. Attending these con- 

 ditions we find the vision is impaired, ciliary irritation, 

 which is aliomjs ominous (a zone of fine vessels appearing 

 around the corneal margin), pain, photophobia, lachry-. 

 mation, conjunctival congestion and contraction of the 

 pupil. The cornea will be turbid and swollen. If 

 ulcerated, it becomes thinned, and perhaps rupturing 

 permits deeper parts to become prolapsed or escape. 

 If thinned or softened it may bulge forward from 

 intra-ocular pressure, forming staphyloma. After 

 recovery, indelible opacities 

 and alterations of curvature 

 may remain, with correspond- 

 ing loss of vision. In treating 

 acute corneal inflammations it 

 Is the cardinal rule to avoid 

 all irritants and caustics and 

 to pay special attention to 

 hygiene and general health. ^" 



Atropine, darkness, and rest of the eye are always 

 proper. Cold and local bleeding may be tried if symp- 

 toms are very acute. When the disease does not 

 improve under this treatment, or becomes chronic, the 

 proper treatment requires special experience. Where
