Pressing the corner of the eye creaking is a normal physiological phenomenon, is due to the tear ducts within the air bubbles caused by the pressure of the air bubbles rupture so as to emit a loud sound. Pressing the corner of the eye creaking sound is a very common situation, not due to disease, but due to physiological phenomena. The lacrimal duct is a normal physiological structure located in the eye and is responsible for the drainage of excess tears produced by the eye into the nasal cavity, where they are absorbed by the nasal mucosa. Sometimes it is possible for air to enter the tear ducts along with the tears, thus forming many small air bubbles in the tear ducts. When the inner corner of the eye is pressed, the tear duct will be squeezed, thus causing the small bubbles in the tear duct to burst under pressure, and a gurgling sound will be made.
