The bruising of your eyelid is definitely from blood leaking into your skin. The causes include rupture of blood vessels most likely the size of
arterioles or venules (in between artery/vein and capillary size), an embolic event which is like a very small clot that got stuck there, or leaking
blood from the vessels due to edema/swelling of the area from an allergic reaction (most likely from contact dermatitis caused by plant or chemical)
or from a coagulation disorder...
The rupture of the blood vessels would most likely occur from blunt trauma or shearing force (like rubbing or scraping the eye). Based on your
history, this is a likely possibility as you were asleep when the problem was developing and it could have been self-inflicted injury.
The embolism possibility seems highly unlikely as there is probably no cause as you don't really complain of other symptoms that may have done this
(i.e., chest pain/flutters/palpitations/shortness of breath/anxiety [atrial fibrillation, pulmonary embolism], calf pain or thigh pain [DVT], etc.)
Leaking blood from edema seems a likely cause as you sound like you had contact dermatitis around the area of the affected eye. The scratches,
itching, rash, swelling prior (if I read your history correctly) was definitely contact dermatitis and I've seen delayed bruising from this cause,
especially in the face due to the fascial planes, several times before. I wouldn't think a coagulation disorder would be a cause as you didn't
mention spontaneously bleeding gums, unexplained bruising, or frequent and heavy nosebleeds.
Also, more than one factor could have been causative, rather than one explanation... I'd probably guess the contact dermatitis combined with a
shearing force like rubbing the eye while asleep. I hope this helps and of course, if you aren't getting better or having further problems, consult
your primary care provider.
