Blepharitis may cause redness of the eyes, itching and irritation of the eyelids in one or both eyes. Its appearance is often confused with conjunctivitis and due to its recurring nature it is the most common cause of "recurrent conjunctivitis" in older people. It is also often mistaken for "dry eye" by patients due to the gritty sensation that may occur, however lubricating drops do little to improve the condition.
As the infection progresses, the sufferer may begin to notice a foreign body sensation, matting of the lashes, and burning. Usually, the primary care physician will prescribe topical antibiotics for staphylococcal blepharitis. Unfortunately this is rarely an effective treatment.
Such a routine needs to be convenient enough to be continued lifelong to avoid relapses as blepharitis is often a chronic condition. But it can be acute, and one episode does not mean it is a life long condition.
