Common presenting symptom of acquired NLDO managed with DCR?

Explanation:
Blockage of tear drainage causes tears to spill over the eyelids rather than draining into the nose. In acquired nasolacrimal duct obstruction, the most common presenting symptom is excessive tearing, or epiphora, which is what prompts evaluation and treatment with dacryocystorhinostomy to restore a drainage route. Diplopia (double vision) suggests eye misalignment or nerve issues, not NLDO. Ptosis is eyelid droop, and photophobia is light sensitivity—neither are typical symptoms of NLDO. DCR creates a new pathway for tears to drain into the nasal cavity, directly addressing the epiphora.
