old people cry
Introduction
Introduction Older friends often complain that "tears" are like "ghosts", and they meet unexpectedly and linger. Going out for morning exercises is filled with tears. When reading or talking, there is no reason for tears and tears. When riding a bicycle, there is a sudden tears of tears and it is dangerous. Some elderly friends continue to wipe their eyes because of repeated tears, which eventually leads to red, swollen, painful, and even erosive eyelids. In order to eliminate the symptoms of tearing, some elderly friends purchased various eye drops, including hormonal eye drops, and the results were not satisfactory. In fact, these worries and fears are not necessary.
Cause
Cause
Clinical data show that about 90% of the elderly have tears that are functional abnormalities. Although these elderly people shed tears, they flushed the lacrimal passages and there was no obvious abnormality in the eyes. The reason is because the eyelids of the elderly are slack and the muscles undergo degenerative changes. On the one hand, these senile changes can lead to abnormal position of the punctum, and on the other hand, the function of the active "pump" can be reduced. "Exportation is not correct" and "discharge is weak" is the main cause of tearing in the elderly. In addition, because the white of the eye (conjunctiva) is loose, the tears can not be properly distributed and flowed directly to the outside of the eye, which is also an important reason for the elderly to cry.

First of all, to rule out eye diseases. Including the lacrimal gland itself disease, trichiasis and so on. In addition, the tears caused by obstruction of the lacrimal passage are excluded, and elderly friends can go to the hospital to wash the lacrimal passage to confirm the diagnosis, or they can make their own preliminary judgment. If the lacrimal passage is completely blocked, the tears will continue to flow along the face; if it is inflamed, redness and pus will appear. The functional abnormalities, and occasionally tears appear, can be relieved by themselves. If it is a lacrimal gland disease, trichiasis, obstruction of the lacrimal duct, etc., it is necessary to go to the hospital for active treatment.
