Blepharitis is inflammation of the rims of the eyelids, which causes them to become red and swollen. Symptoms can include; burning, soreness or stinging in the eyes, crusty eyelashes or itchy eyelids. It is commonly caused by bacterial infection or can be a complication of a skin condition. Blepharitis will often be treated by your GP but occasionally, referral to an Ophthalmologist is required.
