My dog is fine with everything except tears and the corners of my eyes are like two sinks. The lacrimal gland is an accessory organ of the eye. Its main function is to secrete tears to moisten the eyeball. Under normal circumstances, the lacrimal gland secretes tears to moisten the eyeball and then enter the nasal cavity through the nasolacrimal duct, and will not flow out from the corner of the eye. However, if there is a foreign body or proliferative blockage and inflammation, the above situation will occur.

The auditory nerve and facial nerve are alternately distributed on the face, which is a very sensitive area. Because the pain in the deep part of the ear canal will extend to the area around the eyes, it will also stimulate the secretion of the lacrimal gland.
