Blind canalicular marsupialization in complete punctal absence as part of a systematic approach for classification and treatment of lacrimal system obstructions.

The procedure of choice for epiphora caused by bipunctal and canalicular obstruction is conjunctivodacryocystorhinostomy. Despite its high success rate, it may result in multiple complications, such as extrusion, migration, and secondary obstruction. The author describes a simple alternative procedure to conjunctivodacryocystorhinostomy for patients with epiphora caused by bipunctal and proximal canaliculus complete occlusion and a systematic approach to treat lacrimal system obstructions.
