Traction Alopecia from Tight Eyeglasses?

Hello,

from 2010 until September 2011 I was wearing eyeglasses that were too tight, and I suppose the tightly fitted frames lead to a pressure-induced alopecia at both lateral scalp sides, decreasing the blood flow passing through the external carotid artery. I have attached a photo which shows the right side of my scalp, and which shows the reduced hair density.

Is this due to an ischemic process? How do I know if the alopecia is scarring and if this process is reversible? Up until now the hair hasn’t regrown. Thanks a lot

I would think that it is almost impossible to reduce the blood supply enough in that area to produce ischemic changes. The fact that your hair is thin there could be the result of constant rubbing of your eyeglasses if they are as tight as you seem to think. Get glasses that don’t rub and see what happens. Give it 6 months to see if it improves.
