=Treatment.=—Often the treatment is troublesome and the case is very obstinate according to old school methods. Rest, hygiene, general health and habits are looked after. The cause must be found or the treatment cannot be specific. These are the different forms of eye strain as ordinarily classified. Now as we study the reflex symptoms from these and attempt to trace out the reflexes from an osteopathic point of view, we may find some more definite causes of these conditions and consequently some methods of treatment not found in standard text books might naturally suggest themselves. Reflex symptoms that have been traced to eye strain by ophthalmologists are as follows: Constipation, indigestion, heartburn, nausea, vomiting, nervous attacks, fear of impending calamity, irritability, despondency, insomnia, restless sleep, epilepsy, nervous twitchings and enuresis. All these symptoms have been seen to disappear after eye strain was corrected. There is no absolute way of proving that all these symptoms have existed because of eye strain. The existence and disappearance of some of them at the time of treatment for eye strain may be a coincidence. It is evident that eye strain in varying degrees may produce a train of symptoms similar to many above mentioned. A patient, nervous, anxious, uneasy, and despondent, constipated, and having some indigestion, showed on examination contractures and tenderness at the third dorsal. It was found he was suffering from eye strain from overuse of glasses that were too strong for him. The eyes were refitted. He was wearing a (R)+4.50 D. S. = +.50 cyl. Ax. 180. (L)+4.50 D. S. = +.50 cyl. Ax. 90 for close work and a (R)+2.00 D. S. = +.50 cyl. Ax. 180 (L)+2.50 D. S. = +.25 cyl. Ax. 90 for distance. The new glasses were—Reading— (R)+3.00 D. S. = +.25 cyl. Ax. 180 (L)+3.00 D. S. = +.25 cyl. Ax. 180 Distance: (R) + 1.50 D. S. = +.25 cyl. Ax. 180 (L) + 1.50 D. S. = +.25 cyl. Ax. 180 He was fitted two years previously. At that time the stronger glasses were correct. Eyes change more or less constantly, especially between the ages thirty-five to fifty-five years. When glasses are fitted, a weak ciliary muscle after a rest may become stronger and allow weaker glasses to be worn. If a young person is fitted for myopia, in a few years he may discard his glasses as presbyopia develops. A person fitted correctly, who has a strong ciliary muscle may not be able for awhile to see as well with the glasses as without them. After they are worn awhile the ciliary muscle will cease its efforts to accommodate so much and the glasses give the desired effect. In some cases the doctor’s reputation to fit glasses properly may suffer at the hands of such people who sometimes refuse to take glasses, or after getting them refuse to wear them.
