Patient's question:
The baby is 3 years old now. I've noticed that he's been crying a lot recently, and I don't know why. Should I use eye drops?Doctor's answer:
There is a channel between the eyes and the nose called the lacrimal duct, which mainly functions to drain excess tears from the eyes into the nasal cavity. Under normal circumstances, the eyes continuously secrete tears, primarily to lubricate the eyeball. However, when people cry, a lot of tears flow out directly. At the same time, many tears flow into the nasal cavity, similar to a runny nose. If so, I suggest we go to the hospital to check if there is a serious problem.
