Discussion: The condition known as "Dropping Eye" (Zhui Jing) occurs when the eye is exposed to pathogenic wind, causing the blood vessels to suffer from cold. The cold qi penetrates and rushes into the pupil. The wind-cold qi follows the traction of the eye tendons, pulling the eyeball and pupil downward, which is termed "Dropping Eye." If left untreated for a long time, the pupil becomes damaged and sunken, eventually leading to blindness.
