88 VETERINARY OPHTHALMOLOGY. 



Under symptoms^ will find photophobia and lachry- 

 niation, frontal pains of a lancinating nature, which 

 are alioays aggravated at night, the degree of pain 

 being some indication of the severity of the case. 

 The lids will be involved to some degree, usually 

 but slightly, however. Careful examination will re- 

 veal a dull, rusty appearing iris, with often turbidity 

 of the aqueous. The iris from infiltration will re- 

 spond to light in a sluggish manner. There Avill be 

 conjunctival and sub-con jnnctival injection, which is 

 represented by irregularly scattered vessels, which 

 may be moved with the conjunctiva by rubbing on the 

 lower lid, remember, and these vessels may be so en- 

 larged and engorged as to present chemosis. The point 

 wnll be the rosy zone of vessels surrounding the cornea, 

 of a delicate pink — not decidedly red, but a pretty deli- 

 cate pink. The lines radiate in a mathematical manner, 

 i.e., with regularity and precision. They are not 

 affected by movement of the lower lid with the finger as 

 are the conjunctival vessels. The degree of this 

 zone-like injection is a criterion as to the severity of the 

 attack. Adhesions will be noticed, and may be slight 

 or very pronounced, from a slight synechia to complete 

 occlusion of the pupil. If they are not seen or easily 

 diagnosed, the instillation of atropine will discover 

 any, no matter the degree, by irregularities of the 

 pupil. (See Fig. 46.) Not wise to expect resolution 

 this side of six weeks. Maybe met within one or both
