(DCR) surgery is a procedure that aims to eliminate fluid and mucus retention within the lacrimal sac, and to increase tear drainage for relief of epiphora (water running down the face). A DCR procedure involves removal of bone adjacent to the nasolacrimal sac and incorporating the lacrimal sac with the lateral nasal mucosa in order to bypass the nasolacrimal duct obstruction. This allows tears to drain directly into the nasal cavity from the canaliculi via a new low-resistance pathway.
Symptoms:
- Tearing (Epiphora)
- Mucopurulent discharge
- Mattering of lashes and lids, crusting in the morning
- Pain
- Blurred vision from tears
- Bloody tears
- Dacryocystitis (abscess infection of the lacrimal sac in the inner corner of eye area)
