Lacrimal gland generally does not need to be unblocked, clinically, tear duct unblocking is more common, patients can be treated by massage, surgical treatment, such as tear duct probing surgery, tear duct placement, etc.. Lacrimal duct obstruction is a common disease in ophthalmology, which occurs in the elderly, and can lead to the patients’ lacrimal ducts not being smooth, which can’t make the excess tears in the eyes drain into the nasal cavity, and make the patients suffer from the symptom of watery eyes. Currently, patients can have their tear ducts unblocked through surgical treatments to relieve the symptoms of tearing, such as tear duct probing surgery and tear duct placement. In addition to surgery to unblock the tear ducts, children with tear duct obstruction can also have eye massages to promote the unblocking of the tear ducts. It is recommended that patients with lacrimal duct obstruction should consult a doctor to evaluate their condition and choose the appropriate treatment according to the doctor’s instructions.
