What could cause persistent swelling, dryness, and itching of the upper eyelid skin?

Hello,

Welcome to icliniq.com.

Thank you for your query.

Your symptoms are suggestive of meibomian gland dysfunction (MGD) which is the inflammation of meibomian glands present in the eyelids. The function of these glands is to produce sebum to keep the eyes moist. These glands may sometimes get blocked or stop producing good sebum and instead produce bad sebum which leads to dryness and other symptoms. I suggest you follow a few instructions like use warm compresses. Apply azithromycin ointment twice daily along your eyelid margin. Use lubricating eyedrops like Refresh Tears four times a day. This will help you. Having said that, this is a provisional diagnosis. Consult your local ophthalmologist if there is no relief or if the condition worsens. I hope this has helped you. Thank you.
