and posterior ciliary, which come from the ocular 

 branch of the ophthalmic, which in turn comes from 

 the internal carotid. The nerves are from the ciliai'y, 

 which contain ganglion cells containing sensitive, motor 

 and sympathetic filaments, and these pass to ciliary 

 body, iris and cornea. These nerves, you understand, 

 come from the ophthalmic division of the fifth, and 

 the fifth is peculiar in its origiu^to wit., from the floor 

 of the fourth ventricle and side of the pons and the 

 Gasserion Ganglion (this is seusoj'y), and from the floor 

 of the fourth ventricle and side of the pons for its 

 motor root. Contains also sympathetic filaments. The 

 ophthalmic branch enters by the sphenoidal fissure. 



Cyclitis. — Inflammation of the ciliary body. The 

 ciliary body is seldom involved alone. Usually the con- 

 tiguous parts participate. Is as a rule an extension of 

 iritis ; choroiditis. . If the result of operation, or injury, 

 then it may be alone involved. 



Under Symptoms will have ciliary injection accom- 

 panied by chemosis, pain. The eye will be intolerant of 

 touch, and that is the symptom. The iris will appear 

 rusty. This may go on to inflammation of all parts of 

 the eye^panophthalmitis. Prognosis is not good. 



Teeatment — .Hot fomentations, local bleeding, atro- 

 pine, anodynes, etc. If the attack prove rebellious, as is 

 often the case, enucleation, for the safety of the other 

 eye, which, through sympathy, may participate. Injuries 

 are dangerous, principally because of giving origin to
