What is the primary purpose of DCR?

• A. To bypass the nasolacrimal duct and establish drainage from lacrimal sac to nasal cavity
• B. To enlarge the lacrimal gland
• C. To remove the lacrimal sac
• D. To surgically close the tear duct

Answer: (C)

Dacryocystorhinostomy is done to restore tear drainage by bypassing a blocked nasolacrimal duct. It creates a direct opening between the lacrimal sac and the nasal cavity, so tears can drain into the nose again. The lacrimal sac is preserved and remains part of the drainage system; the goal isn’t to remove it. This procedure doesn’t enlarge the lacrimal gland or close the tear duct, and it isn’t about removing the lacrimal sac. By establishing this new route, the blockage is bypassed and drainage is reestablished.
