Hi Prabhu, Welcome to HealthcareMagic Forum.
Your Mother is suffering from Epiphora
as a result of Nasolacrimal Duct
Blockage. In adults it could be due to Infection, Injury
. Until the cause is treated the symptoms will persist.
Take her to Ophthalmologist so that he can examine her eye and suggest Eye exam, Special fluorescein
stain testing to see how tears drain and X-ray studies to examine the tear duct. The exact cause has to be ruled out. You can do some gentle massaging over the area twice or thrice daily. Using a clean finger, rub the area from the inside corner of the eye toward the nose. This may help to open the tear duct. Tear duct blockage may increase the risk of eye infections. She may need antibiotic eye drops.
