DacryocystitisDacryocystitis is an inflammation of the lacrimal sac at the inner corner of the eye. It usually results from blockage of the duct that carries tears from the tear sac to the nose. Dacryocystitis may occur suddenly (acute) or be longstanding (chronic). In acute infection, the area around the lacrimal sac is painful, red, and swollen. The blocked duct harbors bacteria and becomes infected. Slight pressure applied to the lacrimal sac may push pus through the opening at the inner corner of the eye, near the nose. Sometimes, an infection causes fluid to be retained in the lacrimal sac; a large fluid-filled lacrimal sac is called a mucocele. Babies often have recurrent episodes of infection; however, in most cases, the problem resolves as the child grows. In adults, the infection may originate from an injury or inflammation of the nasal passages. In many cases, however, the cause is unknown. Tears drain into little openings (puncta) in the inner corners of the eyelids. This is the location of the lacrimal sac, which is part of the nasolacrimal duct (tear drainage system). This condition most commonly presents when there is obstruction in the tear drainage pathways or a stone in the lacrimal sac. This condition is treated with oral or IV antibiotics depending on the severity, sometimes with hospitalization. Surgical correction of the underlying abnormality, if present, is usually necessary once the infection has resolved. This would typically involve a procedure known as dacryocystorhinostomy (DCR).
