Significant depression of the lower eyelid should be ruled out as being caused by a fracture of the inferior orbital wall following eye trauma. Lower eyelid depressions may also appear if systemic wasting disease has caused a reduction in orbital fat or if aging factors have caused eyelid skin laxity. This symptom may also occur if too much fat is extracted after liposuction of the lower eyelid. In addition, orbital vascular varices or orbital metastatic adenocarcinoma may also present with a similar phenomenon. If the sunken lower eyelid is caused by aging or trauma, it can be observed for the time being, but if you feel that it affects your beauty, you can consider fat implantation surgery to correct the problem.
