From Heritage:

var·ix (v²r“¹ks) n., pl. var·i·ces (-¹-s¶z”). 1. An abnormally dilated or swollen vein, artery, or lymph vessel.

Small capilaries on your eyes, face and nose can break if you are having a really hard time of it. This does not happen to women who are 'imagining' it, or women who 'it's all in their heads'.

I also don't think we use microvarcies much in Englsih. They are usually called spider veins - or telangiectasias for more formal name

Spider veins are the thread-like colored veins most often seen on the surface of the skin. They are most often not as painful as enlarged varicose veins but they are still liable to bleed and worsen without treatment. Spider veins occur most commonly in the legs but are often seen in the face and elsewhere. These spider veins, medically referred to as telangectasias, will not worsen to the point where they will ever become the large bulging varicose veins


Whether you're a man or a woman, you may have noticed fine, little red veins on the nose, chin, or cheeks that weren't there before. These are telangiectasias or facial spider veins, and they appear on both men and women as a normal part of aging. They can also result from pregnancy, childbirth, birth-control pills, estrogen-replacement therapy, sun damage, rosacea, and even corticosteroids. Although not usually a medical problem, telangiectasias can be an aesthetic one that make-up usually doesn't cover adequately.

Varicose Veins
This painful condition, called varicose veins, is extremely common, especially in women. Leg swelling, itching, burning, aching, and the appearance of small branching "spider" veins often accompany this vascular condition.

Heredity is the primary risk factor for developing varicose and spider veins. However, pregnancy, extended periods of standing, obesity and aging can also contribute.
