The Dryness Cycle
Unlike seborrheic blepharitis, this form is driven by a lack of oil production, leading to cracked, irritated, and xerotic lid skin.
Symptom Profile
Patients often experience a burning sensation, the feeling of a foreign body in the eye, and crusting along the lashes that feels brittle.
Tissue Changes
Chronic xerotic inflammation can lead to "tylosis," a thickening and scarring of the eyelid margin that may cause the lashes to turn inward.
Therapeutic Approach
Management involves intensive lid hygiene, warm compresses, and the use of preservative-free ointments to provide a long-lasting moisture barrier.
Frequently Asked Questions About Xerotic Blepharitis
Why is it worse in the morning?
Tear production drops during sleep, and the lack of eyelid movement allows dryness to peak, often causing the lids to feel stuck upon waking.
Can makeup cause this?
Makeup can exacerbate it if not removed properly, but the xerotic aspect refers to a deeper physiological lack of moisture.
Is it permanent?
It is a chronic condition that requires ongoing management, but symptoms can be effectively controlled with a consistent eyelid care routine.
