Final answer:
The excessive tearing from a blocked nasolacrimal duct in a newborn can be treated with methods such as massage of the lacrimal sac, warm compresses, or nasolacrimal duct probing.
Step-by-step explanation:
The excessive tearing from a blocked nasolacrimal duct in a newborn can be treated with several methods:
- Massage of the lacrimal sac: Gentle massage of the lacrimal sac can help to unblock the duct and facilitate the flow of tears. This can be done by applying light pressure upwards and towards the nose.
- Warm compresses: Applying warm compresses to the affected area can help to relieve inflammation and open up the blocked duct.
- Nasolacrimal duct probing: If other treatments are not successful, a healthcare professional may perform nasolacrimal duct probing to physically open the blocked duct.
