It is in the upper, outer corner of my lid underneath brow on bone.
To wholeheartedly disagree with the previous answer, I would absolutely not recommend performing sclerotherapy in this area. I have personally treated hundreds of patients' legs with sclerotherapy, but have only treated 1 temple vein (with extreme caution), if that tells you anything. The risk here is that the injected product could migrate into the veins and arteries of the veins feeding the eye and retina, causing blindness or other eye injury. I think phlebectomy (removal with a hook) could be an option, but you should be properly evaluated in person.
The pictured vein can be safely treated by several methods including sclerotherapy, topical laser or removal through tiny incisions. I would use sclerotherapy.
