INFLAMMATION OF THE EYELIDS.

The eyelids suffer more or less in all severe inflammations of the eye,
whether external or internal, but inasmuch as the disease sometimes
starts in the lids and at other times is exclusively confined to them,
it deserves independent mention.

Among the causes may be named: Exposure to drafts of cold air, or to
cold rain or snow storms; the bites or stings of mosquitoes, flies, or
other insects; snake bites, pricks with thorns, blows of whip or club;
accidental bruises against the stall or ground, especially during the
violent struggles of colic, enteritis, phrenitis (staggers), and when
thrown for operations. It is also a result of infecting inoculations, as
of erysipelas, anthrax, boil, etc., and is noted by Leblanc as
especially prevalent among horses kept on low, marshy pastures. Finally,
the introduction of sand, dust, chaff, beards of barley and seeds of the
finest grasses, and the contact with irritant, chemical powders,
liquids, and gases (ammonia from manure or factory, chlorin, strong
sulphur fumes, smoke, and other products of combustion, etc.) may start
the inflammation. The eyelids often undergo extreme inflammatory and
dropsical swelling in urticaria (nettlerash, surfeit) and in the general
inflammatory dropsy known as purpura hemorrhagica.

The affection will, therefore, readily divide itself into (1)
inflammations due to constitutional causes; (2) those due to direct
injury, mechanical or chemical; and (3) such as are due to inoculation
with infecting material.

(1) Inflammations due to constitutional causes are distinguished by the
absence of any local wound, and the history of a low, damp pasture,
exposure, indigestion from unwholesome feed, or the presence elsewhere
on the limbs or body of the general, doughy swellings of purpura
hemorrhagica. The lids are swollen and thickened; it may be slightly or
it may be so extremely that the eyeball can not be seen. If the lid can
be everted to show its mucous membrane, that is seen to be of a deep-red
color, especially along the branching lines of the blood vessels. The
part is hot and painful, and a profuse flow of tears and mucus escapes
on the side of the face, causing irritation and loss of the hair. If
improvement follows, this discharge becomes more tenacious, and tends to
