Demodex without collarettes? Or few?

I ve spoken with 10 ophthalmologists in the last 5 months. The majority of them told me my eyelashes were clean and that I was loosing them due the inflammation ( blepharitis/rosacea ) BUT 2 of them told me that demodex brevis living inside the follicles show now signs outside and make the eyelashes to fall + ruining mebium. I don't know what to think!
