Only the general symptoms are of importance in eye derangements. The special belong to ophthalmology. Photophobia (dread of light) may be due to hysteria, a brain lesion, or an inflammatory disease of the eye.

Ulceration of the cornea is often an index to the state of the blood--often indicates heavy meat-eating, with consequent toxins in the blood.

Dropping of the upper eyelid may mean paralysis of the third pair.

Protrusion of eyeballs, with heart symptoms, indicates exophthalmic goiter. If but one eye protrudes, it indicates a tumor behind the eye.

Long vision, with lost accommodation of light, means ataxia or paralysis. This is the Argyll-Robertson sign. A bright spot before the eyes (scotoma), with loss of power to contract the pupil before a light, may indicate optic neuritis or tabes. If no other symptoms of tabes can be found, it is an eye lesion.

If a person, deaf in one ear, can hear a watch tick, or a tuning fork, placed on top of his head, equally well with both ears, the disease is not central.

When taste and smell are diminished, it is probably due to toxin poisoning, including tobacco, alcohol, coffee, and tea.

A headache is rare indeed that will not get well after the patient corrects his eating and other habits.

A crisis of tears differentiates a hysterical from an epileptic paroxysm.

Purulent ophthalmia is often an indication of gonorrheal infection.

Halos of light, or scintillations passing from a light, indicate indigestion in children.

There are many eye lesions that will pass away when all stimulants are given up. Toxin poisoning must be overcome by eating in keeping with the digestive power. Venereal abuse brings on enervation of the eye and brain, and, unless corrected, no cure can be made. Adopting glasses for many eye defects caused by excesses in sensuality is the height of nonsense.

When noises disturb and prevent concentration, in those who are trained to concentrate or give attention, the nerves are on edge, and the cause is overstimulation--overeating, coffee, tea, tobacco, alcoholics, excessive venery.

If, by applying the ear or stethoscope to the patient's ear, the physician can hear a crackling sound when the patient swallows with his nose and mouth closed, it indicates that the tympanum is intact.

Taste and smell are often much impaired by catarrh.

It can be said that all the special senses are more or less impaired by a style of eating that builds toxin poisoning.
