Tearing: lacrimal obstructions.

Tearing disorders are relatively common. Comprehensive consideration of the entire tearing system can assist the diagnosis and treatment of tearing problems to improve, if not cure, the condition. The general symptom complaint of "tearing or a feeling of wetness/irritation" most commonly relates to a dry or irritated eye, which usually responds well to medical therapy or punctal occlusion. True tearing from a lacrimal obstruction, however, is usually treated surgically. With a thorough understanding of the anatomy and physiology most tearing problems can be systematically analyzed, diagnosed, and treated with a high degree of satisfaction to the patient and physician.
