Pronounced: Dak-re-o-sis-ti-tisEn Español (Spanish Version)
The lacrimal sac helps drain excess tears from the eye. The sac starts near the inner corner of the eye and runs along the side of the nose. Tears move through tear ducts into this sac. The tears are then passed out into the nasal passages.
Dacryocystitis is swelling and irritation of this sac, which may also be infected.
Dacryocystitis is caused by a blocked tear duct. Tears become trapped in the sac and form a pool. Bacteria can then begin to grow in the tear pool and create an infection. Both the trapped tears and infection will cause swelling and irritation.
