Blue Veins Above Eye, Extends to Hairline. Can I Do Anything?

You should see an Oculoplastic surgeon who is the expert on eye related vascular issues.  They can advise on your risk profile for the procedure.

These veins are common, and I often see them on patients with lighter complexions or who have low body fat.  It's difficult to say for sure what might be the best option without seeing you in person, but laser treatment may be a good option.  Also in some cases a simple minor surgical procedure may be necessary.  I would not recommend sclerotherapy in this area.  The bottom line is that this should not involve any high risk procedures.   I hope this helps answer your question.

These are called temporal veins, forehead veins or periorbital veins and can be treated by lasers if small, sclerotherapy effectively or sometimes RF technology. We routinely treat such veins in our medical office. The largest of these veins may occasionally need microphlebectomy or microligation.
