PUNCTAL OCCLUSION is a simple procedure that is both overused and underused. There are several techniques for performing punctal occlusion, and the indication for the punctal occlusion influences the approach used. At one end of the spectrum, punctal occlusion is an essential part of the management of severe cases of dry eyes resulting from an aqueous deficiency associated with rheumatoid arthritis. However, epiphora can be a very troublesome complication that may require surgical correction when punctal occlusion is performed in patients who have symptoms of ocular surface disease not caused by aqueous tear deficiency.1
