What causes distichiasis?
In most cases, distichiasis is congenital, which means it’s present at birth. It can be caused by a genetic mutation that’s linked to heart problems. You can also get distichiasis later in life if your eyelids are inflamed or injured.
How common is distichiasis in dogs?
Distichiasis is quite common in dogs. Distichiasis is a condition in which extra hairs grow out of the eyelash area. It happens when there are two or more hairs growing out of a Meibomian gland opening. (Meibomian glands are located along the margin of the eyelid.)

What causes blepharophimosis?
BPES is caused by a mutation in a gene called FOXL2, which controls the production of the FOXL2 protein. This protein, in turn, is involved in the development of the muscles in the eyelids as well as the growth and development of ovarian cells.
