Recurrent Ophthalmia. 
During the latter part of 1909 and first part of 1910 we 
had a horse referred to us suffering with recurrent ophthalmia 
or moon blindness. This affection, as suggested by its name, 
is supposed to have some relation to the lunar periods. Some 
points in our work showed that such may be the case. Attacks 
appeared not infrequently at the time of full moon, and in our 
only experimental infection 28 days elapsed between inocula- 
tion and a general ocular inflammation. 
This affection manifests itself as a conjunctivitis early in 
the attack but rapidly progresses to an iridocyclitis and lastly 
to a panophthalmitis. After each attack the ball is smaller 
until it is so shrunken as to be sightless from chronic thicken- 
ing and opacities. The causation is not known. The disease 
behaves not unlike an infectious one, remaining in a stud for 
years at a time. Not every horse may be affected. It has 
been connected with dampness, bad fodder, overwork and the 
like. Again others have connected it with malaria or rheu- 
matism. Potapenke, Vigezzi, Koch and others have found 
various micro-organisms, no two of which seem to be the 
same. Even an animal organism like malaria has been 
described. [Whether or not malaria has anything to do 
with the disease, it must be said that our horse was favorably 
affected in regard to temperature as well as to the eye condition 
by repeated subcutaneous injections of Quinine Bisulphate.
