3o6 VETERINARY HOMCEOPATHY. 



tions where stagnant water is found in abundance. The onl>' 

 satisfactory method of treatment in such cases is to puncture the 

 eyeball and allow the parasite to escape with the aqueous humor; 

 this operation, however, should not be attempted by a layman, or 

 permanent injury to the organ would most probably be the result. 



Fungus H^Ematodes is a form of disease that we have on several 

 occasions met with; it consists of a dark vascular tumor, of a 

 malignant character, that forms at the back of the eye, and unless 

 arrested spreads until the whole of the eyeball and sometimes the 

 bones which help to form the socket of the eye are involved; the 

 cases that have come under our notice were all so far advanced 

 that we made no effort to treat them medicinally, but performed 

 the operation of removal of the whole organ; and after the heal- 

 ing of the parts was completed one case was furnished with an 

 artificial eye that answered the purpose of concealing the unsightl}^ 

 appearance which an empty socket presents. 



Could the disease be discovered in its earlier stages, and before 

 it had invaded the organ too far, we should think thaXPhosphonis 

 3x and Hydrastis ix might be administered with some good pros- 

 pect of arresting further development and so affecting a cure. 



Cataracts are opacities of the crystalline lens or its capsule,, 

 which prevent the rays of light from passing on to the retina and 

 thus produce complete blindness or imperfect sight; it is under 

 the latter condition that horses are rendered somewhat dangerous, 

 especially to inexperienced drivers, from the tendency to shy, a 

 habit which is due to the inability of the animal to properly dis- 

 cern various objects on the road. In this country cataracts are 

 attributed to frequent attacks of ophthalmia; whether this is cor- 

 rect or not we are unable to say; but we confess to being some- 

 what sceptical about it ; on the other hand it is generally admitted 

 that cataracts of one or both eyes develop independently of any 

 preceding inflammation; it is hardly possible to positively diagnose 

 the presence of cataracts without the aid of the ophthalmoscope; 

 the majority of veterinary surgeons claims to be able to recognizp 

 the condition without the aid of this instrument, but for our own 

 part we prefer to rely upon more positive evidence than is obtain- 

 able by trusting to our unaided sight. In the human subject 

 cataract is said to be due to various cau.ses, viz. , to diabetes; to 

 old age; in association with some established constitutional disease;
