=Therapy.=—Diet should be bland; the eyes should be protected from irritants; yellow oxide ointment should be used in the eye once a day or 10% argyrol. The ointment is preferred. Moist warm compresses on the eye are comforting. A boric acid wash in almost all conjunctival trouble is good. If there is much irritation giving a suspicion of iris involvement a drop of atropine ½% should be used. The general regimes of living should be regulated. Osteopathic treatment should be directed toward building up the general health and correcting all lesions, especially that may have a specific bearing on the eye trouble. Such lesions will be found more often at the first, second and third thoracic, but may be anywhere from there to the occiput. Vernal Conjunctivitis This disease is known by many as =vernal catarrh= or =spring catarrh= of the conjunctiva. It is a chronic inflammation which sets up changes in the conjunctiva and tarsus. This disease may be confused with trachoma unless one observes closely. There are broad flat papillæ on the conjunctiva. These papillæ may readily be taken for granulations. They are larger than the granules in trachoma. They somewhat resemble the arrangement of cobble stones. The conjunctiva has a bluish-white filmy appearance called by some, milky shimmer. The disease was thought at first to appear only in the spring, hence the name vernal. Many cases continue through the year with exacerbations in the spring. It occurs more often in boys. Both eyes are attacked. It may heal and leave no trace. It may last from four to twenty years. =Causes.=—Almost all works on the eye say the cause is not known. De Schweinitz says, “Definite information in regard to the cause of this disease is lacking.” There may be a micro-organism which has not been discovered. I wish to call the attention of the osteopathic profession to the great fact that there are numbers of diseases of the eye as well as of other parts of the body about which the medical profession are entirely “at sea.” This gives valuable ground for scientific research by our profession. My experience with this disease is not sufficient for me to speak with any positiveness or finality as to its cause. The altered trophic parts and the very chronic condition existing leads me to the firm belief that we will ultimately find the cause as a mechanical lesion affecting the trigeminal or sympathetic (or both) nerve connections. Glare of light and local irritants act only as secondary causes. Nasal disease may be associated and act as a cause. =Symptoms.=—There is photophobia, some mucus, slight pericorneal injection, redness of the conjunctiva of both the bulb and lids; that of the lids is thickened and of dull pale color due to sub-epithelial hyaline thickening. The fact that there is no pannus, and flat granulations and recurrence with spring, marks it from trachoma.
