ŒDEMA OF EYELIDS.

In anthrax, malignant œdema, disease of heart, kidney or liver,

distomatosis, trichiniasis, wasp stings, urticaria, petechial fever.

Treatment: correct general disorder, remove local irritant, antiseptic

astringents.

An œdematous condition of the eyelids with or without inflammatory

conditions may be due to local disease or it may be the result of more

general disorder. In anthrax districts any of the herbivora, but

especially cattle and sheep, are liable to a diffuse anthrax of the

eyelid with a special petechial or brownish condition of the palpebral

conjunctiva. Malignant œdema and other local bacteridian affections

affect the loose textures of the eyelid in a similar manner, but with

extrication of gas and crackling under pressure. Such cases are

complicated by local inflammation. When in the absence of inflammation

the lids pit on pressure, one should seek for some disease of the heart,

kidney or liver, also for indications of similar dropsical effusions in

other parts of the body. Distomatosis and, to a less extent, pulmonary

and duodenal strongylosis are especially common factors in sheep. In

distomatosis (liver rot) a simultaneous dropsy is often present in the

intermaxillary space, the chest or the abdomen. The puffiness of the eye

is especially marked in the palpebral conjunctiva, and is exposed by

everting the eyelid over the tip of the finger. In trichinosis in man

and less frequently in swine, dropsy of the eyelid is often present at

the end of the first week. Other swellings of the lids partaking more of

the nature of inflammation, result from the stings of wasps, hornets and

other insects, from urticaria (in horses especially) and from petechial

fever in solipeds.

In _treating_ such cases the general disorder, if present, must be first

attended to, then the removal of any local irritant, and finally the

antagonizing of any local inflammation or infection. Astringent and

antiseptic lotions are especially called for.
