Sunken eyes may be related to orbital violent fracture, consumptive diseases, postoperative tumors and so on. 1. Violent orbital fracture: when orbital impact increases orbital pressure, the weak orbital bone wall ruptures, and intraorbital tissues are herniated or embedded, resulting in sunken eyes. 2. Consumptive diseases: if it is bilateral eyeball invagination, it is usually accompanied by consumptive diseases, such as liver cancer, stomach cancer and other related diseases. It causes excessive wasting of the body, which leads to the reduction of intraorbital fat, and then the eyeballs will be sunken in. 3. Postoperative tumor: if there is benign tumor in the orbit, it will press the orbital fat for a long time, resulting in orbital fat atrophy. When the tumor is removed from the orbit, due to the decrease of orbital content, the eyes will also be sunken in. When eyes are sunken in, it is recommended to consult a doctor in time, follow the doctor’s instructions and then conduct further relevant examinations, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
