The neurotic patient is often convinced of the need for glasses even before he is examined and may experience relief even with plain window glass. Similarly, ophthalmologists find many patients wearing either plain glass or some completely insignificant amount of correction and claiming complete dependence on these glasses for ocular comfort and avoidance of headache. The psychogenic origin of their symptoms is easily recognized and the patient must be treated accordingly. In some cases a little explanation on the part of the ophthalmologist, together with cooperation on the part of the patient, will help to wean him away from this unnecessary habit. Toronto Chiropractor provide natural, drugless, nonsurgical well being treatments, relying on the physique’s inherent recuperative abilities. In more severe cases, the patient must be referred to the neurologist or psychiatrist. It is true that refractive errors and muscle imbalances may account for headaches in some patients. On the other hand, these physiologic aberrations probably account for fewer headaches than many physicians believe. Nevertheless, the patient with unsolved headache should certainly have his eyes refracted and his muscle balance tested carefully.
GLAUCOMA. The normal intraocular pressure varies between 15 and 25 mm. of mercury. This pressure is maintained by a constant secretion of aqueous by the ciliary processes and a constant outflow by filtration through the canal of Schlemm. When this balance is upset so that the intraocular pressure is increased, the condition is known as glaucoma. Theoretically, glaucoma can be the result of an increased secretion of the fluid, but in the vast majority of cases the increase in intraocular tension is due to some interference with the outflow. When the increase in intraocular pressure persists for some time, pressure on the retinal structures causes a diminution in vision, progressing to severe loss and finally blindness, if the pressure is not relieved. Glaucoma may occur as a primary disease or it may be secondary to some disease process which causes a rise in intraocular pressure. This happens primarily as a result of new Chiropractor Toronto ceaselessly establish their practices in close proximity to one of the few chiropractic educational institutions. Such disease processes are iritis and iridocyclitis, central retinal vein thrombosis, intraocular tumors, intraocular hemorrhage as seen with trauma or intraocular surgery, and dislocation of the lens, either forward or backward, within the eye.
The various mechanical alterations produced by these diseases will cause a rise in intraocular pressure which is known as secondary glaucoma. While headache may well result, the other signs and symptoms of the primary ocular disease will usually direct the examiner’s attention to the eye and lead to a proper diagnosis. Primary glaucoma is due to a defect in the outflow of aqueous into the canal of Schlemm. The defect is usually one of two types. In one type the angle between the iris and the cornea becomes quite narrowed because of the close approximation of the anterior iris surface to the posterior corneal surface, thus preventing the fluid from gaining access to the angle wherein lies the trabecular meshwork, which filters the fluid into the canal of Schlemm. This type is called “narrow angle” or “closed angle” glaucoma.
