Painless and effective blepharitis treatment

Blepharitis is one of the most common eye conditions seen by eye-care professionals with the overall prevalence of patients reporting the condition approaching 50 per cent.1 Because the eyelid is one of the few body parts that rarely receives thorough cleansing, staphylococcal biofilm accumulates along the lid margins over time. Whether these bacteria originate on the lids or migrate up from the nasal cavity early in life remains unknown, but we do know that they tend to increase with age. This may partly explain why concurrent ocular surface disorders such as meibomian gland dysfunction and dry eye also tend to increase with age.

Despite its prevalence, blepharitis is largely ignored by clinicians because few treatments offer the potential for true success. Patients are often reluctant or incapable of performing lid scrubs with the necessary force and in the appropriate location to affect biofilms in a meaningful way. Ideally, treatment for blepharitis should consist of in-office therapy, performed at the time of diagnosis, and provide a mechanism to remove the inflammatory exotoxin-laden biofilm and stop progression to more severe forms of ocular surface disease.

Mechanical debridement of the lid margin has been advocated in the treatment of meibomian gland dysfunction and this technique may be helpful in removing biofilm to some degree. Unfortunately, this procedure can potentially induce microtrauma to the lid margin, allowing bacterial pathogens direct access to the underlying tissue. Scraping is inefficient and leaves behind residual bacteria, which allows the biofilm to ­re-establish itself quickly and easily.


Microblepharoexfoliation (MBE) is a new technique for removing biofilm from the eyelid margin. It is an in-office procedure performed by the optometrist using a patented instrument called BlephEx, a hand-held device that rotates a PVA sponge soaked in a commercial eyelid cleaning solution. With microblepharoexfoliation, the lid margins are debrided and exfoliated, and the meibomian glands are unroofed. With the sponge tip rotating at about 2,000 RPM, the biofilm and exotoxins are removed, and bacterial overload is debulked. The procedure is also likely to reduce the population of bacteria to below the quorum sensing numbers that induce virulence factor production.2

MBE is easy to learn and can be mastered after one or two procedures. The BlephEx device may be used with either hand and is held like a pen, cradled between the index finger and thumb. After soaking the disposable sponge tip in cleaning solution, the rotating head is applied to the base of the lashes with firm pressure, moving along the lid margin in small increments for 20 to 30 seconds.

After the first pass, the rotation of the sponge tip is reversed and the lid margin is retreated in a retrograde fashion, being sure to cover not only the lashes but also the lid margin back to the mucocutaneous junction. Both upper and lower lids are treated in a similar fashion, and a new tip is used for each eyelid to ensure elimination and disposal of accumulated bacteria.

Although the treatment is painless, many patients describe a tickling sensation due to the vibration of the rotating tip. For this reason, it is recommended to use a drop or two of 0.5% tetracaine before the procedure.

After the lids have been thoroughly cleaned, the excess surfactant is lavaged from the eye using balanced salt solution or sterile eye wash.

Home lid scrub therapy can and should be employed after MBE, but because this does not offer the same efficacy as BlephEx, biofilm will reaccumulate over time. The patient should understand that even in the absence of symptoms, low grade inflammation can cause a slow disruption of the normal lid and tear film anatomy. Repeated MBE treatments are important and should be performed every three to six months.
