d." This is a very serious disease and
a physician should be called.

Treatment. What to do first.--Confine the patient in a darkened room and
if the attack is severe in bed.

Local Treatment.--Dry or moist heat should be applied, according to the
ease they give. Leeches are good in severe cases placed near the outer
corner of the eye. Atropine usually made of about the strength of two to
four grains Atropine to an ounce of water; or one per cent (1 to 100) may
be used, and it should be dropped into the eye from three to six times a
day. The pupil must be dilated and kept so from the beginning to keep the
adhesions from forming between the iris and lens. If too much is used the
throat and tongue will feel dry, face will flush, and there will be
dizziness and a rapid pulse. Stop it until that effect is gone and then
cautiously use it again. The bowels should be kept open.

The diet should consist of milk to a great extent. Water of course can be
taken freely. Soups, broths, gruels, etc., can be used if desired; but
meats should be withheld for a time unless the patient runs down.

Caution.--If a person has any of the special symptoms above mentioned it
would be prudent to begin treatment at once. The great danger is permanent
adhesion of the iris to other parts, especially the lens, and the dilating
and contracting power may be lost.

INJURIES OF THE IRIS.--Concussion of the eyeball may produce an irregular
dilation of the pupil. This is due to paralysis of the sphincter muscle of
the pupil, but it generally disappears. The edge of the pupil may be torn
in the form of one or more rents, or the iris may be separated from its
root at its circumference, leaving a clear space, or it may be entirely
torn from its attachment.

Perforating wounds are accompanied by injury to the lens and other
structures; when the cornea is wounded it is often complicated by falling
of the lens. When a small foreign body passes through the cornea and iris
a small opening may be seen. The greatest danger from wounds is due to
infection and if it reaches the iris, it may produce violent iritis. If
the lens is displaced or absent the iris being without support, will
tremble with every movement of the eye. In some cataract operations, if
there is a loss of the "Vitreous" body a part of the iris may be folded
upon itself, thus enlarging the pupil in that point.
