Inflammation of the tear discharge system in the corner of the eye next to the nose, usually caused by a blockage of the tear duct (as in new-born babies). In older people, inflammation of the tear duct usually leads to chronic inflammation. The symptoms are continual watering of one eye, and pus in the eye. Pus is released when there is pressure in the corner of the eye next to the nose. Chronic inflammation of the lachrymal sac can develop into acute inflammation, with a painful red swelling occurring in the corner of the eye. The eyelids also swell up as a result of the inflammation, and the patient may have a fever. The treatment of inflamed lachrymal sacs in new-born babies consists of administering antibiotic eye drops and massaging the blocked tear duct several times a day. If this is not sufficient, an ophthalmologist can unblock the tear duct by rinsing or by using a probe. When chronic inflammation of the lachrymal sac occurs in older people, the same approach is adopted. However, an operation is sometimes necessary. If acute inflammation of the tear duct arises, the patient must remain in bed and antibiotics are administered. Compresses are applied to the inflammation. The abscess may possibly be lanced. After this, an operation is usually required to form a new tear duct.
