Sunken upper eyelids/Upper eyelid hollowness can be due to the following:
1. Genetics
2. Aging-related atrophy/loss of upper eyelid fat tissue
3. Iatrogenic causes such as post eyelid surgery volume loss, especially eyelid surgeries that were done in the past where surgical techniques and equipment were not as advanced as recent years.
4. Aponeurotic ptosis where there might be thinning of the upper lid, deepening of the eyelid sulcus and a raised upper lid crease resulting in the upper eyelid loking sunken/hollow.
Treatment options will include:
1. Filler injections to correct the hollowness/volume deficit by an experienced doctor who is proficient with fillers over this area of the face
2. Fat grafting or transpositioning of upper eyelid fat pads by a plastic surgeon
3. Surgical repair by an eye surgeon if it's due to aponeurotic ptosis of the eye
