Blepharitis is an inflammation of the eyelids, often caused by bacteria, skin conditions, or blocked oil glands. Symptoms may include redness, swelling, itching, and crusty flakes at the base of the eyelashes. It can affect one or both eyelids and is usually a chronic condition that requires ongoing management. Treatment for blepharitis typically involves good eyelid hygiene, such as warm compresses and eyelid scrubs to remove debris and reduce inflammation. In some cases, doctors may prescribe antibiotic ointments or medications to help control the condition. Regular care can help alleviate symptoms and prevent flare-ups.
