What is a blepharitis assessment?
Blepharitis is a chronic inflammatory condition affecting the eyelids that is extremely common in the UK. It causes symptoms including red, swollen, or itchy eyelids, crusty or flaky debris at the base of the eyelashes, a gritty or burning sensation, and in many cases contributes to or worsens dry eye disease. Although blepharitis is rarely sight-threatening, it is often uncomfortable and persistent, requiring ongoing management rather than a one-off cure.
A blepharitis assessment involves a detailed examination of the eyelid margins, eyelashes, and meibomian glands under magnification using a slit lamp. Your optometrist will look for signs of bacterial overgrowth, Demodex mite infestation (a surprisingly common contributor), meibomian gland dysfunction, and any associated skin conditions such as rosacea or seborrheic dermatitis. Understanding the specific type of blepharitis you have is essential for choosing the right treatment approach.
Treatment is tailored to the cause and severity and may include a daily lid hygiene routine (warm compresses and lid scrubs), antibiotic ointments or drops, anti-inflammatory treatments, and in-practice procedures such as BlephEx (mechanical lid debridement) or thermal pulsation therapy (LipiFlow). Many opticians now run dedicated blepharitis and lid health clinics as part of their dry eye services, offering a level of specialist care that was previously only available in hospital settings.
