74 VETERINARY OPHTHALMOLOGY. 



often a cloudiness which will be prominent during' 

 convalescence will clear up to a very satisfactory de- 

 gree. But the reverse may obtain. During the heal- 

 ing process vessels may be seen traversing the cornea, 

 but this is physiological and necessary to absorption. 

 Suppurative inflammation may result from many and 

 identical causes with other forms, and is the dread of 

 operators. Bruised and lacerated wounds are also apt 

 to give rise to suppuration. Cases of severe conjunc- 

 tivitis sometimes result so. 



Treatment includes the ordinary remedies for kera- 

 titis, remembering to avoid all irritants. Even large 

 hypopyon are absorbed, and it is very seldom necessary 

 to evacuate. Paracentesis may be frequently repeated 

 in cases of increased tension. Hot fomentations are 

 often useful, especially in asthenic cases, where there 

 is danger of death of tissue. In deej) ulcers it is better 

 to perform paracentesis through their base than to 

 permit spontaneous perforation. In ulcers that are 

 stqyerjicial and indolent, Scemisches operation is indi- 

 cated and performed as follows : 



Introduce (after cocaine) a spring speculum ; grasp 

 the conjunctiva opposite point of counter puncture 

 with fixation forceps, (fig. 37) enter the cornea at right 

 angles with a Graefe's knife (fig. 38) thus dividing the 

 minimum amount of tissue ; then turn the knife in- 

 ward, avoiding the iris and lens. Make this primary 

 incision inside the ciliary region, on account of risk
