In case of cyclitis there is an exudate from the ciliary body into the posterior chamber. This may cause a total adherence of the iris to the crystalline lens. With the ophthalmoscope, opacities in the vitreous may be noticed. These are exudates. The tension of the eye is liable to increase a little at first but as the exudates absorb there is more or less softening. Vision is low. Also in cyclitis there is ciliary injection, photophobia, lacrymation and pain, similar to that of iritis. Pressure on the eye ball will reveal a very tender condition around the sclerocorneal junction or over the area of ciliary injection. The causes of iritis, cyclitis or iridocyclitis frequently are systemic conditions and infection such as syphilis, rheumatism, gonorrhea, tuberculosis, infectious diseases and metabolic changes, it may be of traumatic origin or sympathetic. Fuchs says “There are many cases of iritis for which no cause can be discovered and therefore which cannot be placed under these causes.” We agree with him and advance the theory of cervical and upper dorsal lesions or trouble in the sinuses, nose, nasopharynx or throat. No doubt osteopathy can throw some important light on the causes of diseases of the iris and ciliary body. The nose and throat should be examined in all these cases. =Treatment.=—Atropine must be used in the sore eye to put the iris and ciliary body at rest and dilate the pupil to draw it back from the lens so that adhesions may not form. Warm compresses will give much comfort. Sweating should be brought about. All fluid should be reduced to a minimum. Diet should be very moderate and the bowels kept unusually free. The eye should be protected by dark goggles. Thorough treatment of the neck and upper dorsal region with attention to the nose and throat should be given. Constitutional treatment should be given according to the indications mentioned under causes. If annular synechia or total posterior synechia form or there is atrophy of the eyeball operative work may be needed. Also for injuries, tumors, anomalies and so forth of the iris see the latest medical works on this subject. Diseases of the Choroid The =choroid= is the vascular tunic of the eye. With the iris and ciliary body it forms the =uvea=. The iris and ciliary body are rich in nerve terminals and when inflamed; pain is a prominent symptom. The choroid has no sensory nerve terminals. When it is involved alone; pain is not present however severe the pathology. Embryologically Descemet’s membrane is a part of the uvea. When the uveal tract is diseased we frequently note symptoms of a descemetitis as a turbidity of the anterior chamber and spots on Descemet’s membrane. When one part of the uvea is inflamed the tendency is to pass to the other parts because of the intimate blood supply. Choroiditis There are many forms of choroiditis given by writers according to the clinical picture and the pathology.
