Lacrimal Obstruction

Common Conditions and Surgical Repair. An operation bypassing a blocked tear duct, termed Dacryocystorhinostomy (abbreviated as DCR, creates a new passage from the tear sac directly into the nose ( F).

Punctal Stenosis is narrowing of the punctum (B). This may prevent tears from entering the normal drainage pathway. This can be addressed through a small snip incision to enlarge the punctum termed, Punctoplasty.

Dacryocystitis: Blockage of the tear duct results in stagnation of the tears in the tear sac, and the potential for infection in the tear sac shown below. This is typically treated with oral antibiotics or in advanced cases, like that shown below, surgical drainage. A dacryocystorhinostomy (DCR) described above can prevent an infection from reoccurring and solve chronic tearing.
