Fat augmentation to delicate eyelid area?

I'm sorry to hear about your condition and the distress it's causing you. In terms of addressing the visible veins and loss of adipose tissue in the periorbital area, including the upper lids, fat injection is a potential solution that your plastic surgeon can consider.
The injection of fat, also known as fat grafting or fat transfer, involves taking fat from another part of your body, such as the abdomen or thighs, and injecting it into the targeted area to add volume and improve contour. In the upper lids, fat can be injected into the upper part of the lids to address loss of volume and provide a more youthful appearance.
Regarding the part of the lid that covers the eyeballs, known as the globe or cornea, it is generally not recommended to inject fat directly into this area. This is due to the delicate nature of the tissues surrounding the eye and the potential risks associated with injecting fat into the eyeball or its immediate surroundings.
However, there are other surgical options that may be considered to address visible veins or volume loss in the periorbital area, such as skin or muscle tightening or repositioning, or dermal fillers. It's important to consult with an experienced plastic surgeon who can evaluate your condition, discuss your goals and concerns, and recommend the best course of treatment for your individual needs.
