Dermatologic skin problems can cause blepharitis.
This includes rosacea and seborrheic dermatitis. The condition can be mild or severe – chronic or occasional.
Whether the cause of your blepharitis is seborrhea or rosacea, the symptoms are similar.
They include redness, swelling and irritation of the eyelash line. Your eyes can feel gritty and irritated. There may be a greasy feel to the skin with crust and scale situated along the lash line, and that gets stuck to your eyelashes.
The condition involves the skin, eyelash follicles and lash line oil glands. There are many oil glands along the lash line and they become inflamed when you have blepharitis. Eyelashes may fall out or grow haphazardly because of the inflammation.
It is important to see a doctor if simple hygiene measures I mention below do not improve your blepharitis because infection and eye damage can occur when the lash line is chronically inflamed.
How do you know if your blepharitis is due to seborrhea, rosacea or another cause?
Seborrheic blepharitis usually happens when you have really severe dandruff in the more usual areas like your scalp and face, but it can also happen by itself. As with the other manifestations of dandruff, we don’t know the cause of seborrheic blepharitis.
Additionally, the condition tends to clear and then relapse. To learn more about seborrheic dermatitis, click here.
Rosacea blepharitis usually happens in the company of rosacea, which is another common facial rash. Rosacea occurs more on the “apples” of the face such as the cheeks, mid-forehead, chin, and nose. It can involve pimples or red bumps, flushing, facial sensitivity, and stinging. It can also be accompanied by enlargement of oil glands.
