Blepharitis, flashers and floaters

If like me, Ophthalmology training in medical school seemed like a blur (and that was just the view through the fundoscope!), you’ll hopefully find this update on blepharitis and flashes and floaters helpful.


Taken from the BMJ 10 minute consultation series (BMJ 2012;345:e3328), this useful reminder summarises management of this common condition.


  • Look for bilateral, usually symmetrical scaly/crusty/erythematous eyelids, possibly with conjunctival injection and small yellow plugs on meibomian glands.
  • Rule out other pathology including:
    • Dermatological conditions around the eyes.
    • Chalazion (meibomian cyst).
    • Mis-directed eyelashes (trichiasis) or missing lashes (madarosis).


Blepharitis can be chronic, so ensure the patient understands that treatment may only control rather than cure symptoms.

  • Use warm water compresses to soften crust and scale.
  • Clean eyelids with cotton bud soaked in baby shampoo or bicarbonate of soda.
  • In resistant cases, use chloramphenicol/fusidic acid for presumed Staphylococcus infection.
  • Treat persistent meibomian cyst infections with oral doxycycline (100mg daily for 6w).

"I started using LocumDeck as one of our locums used it. It was easy to see her availability and when bookings are made I get confirmation of the booking and can view them on the calendar too. When invoices are sent, I can see it on the site, and digitally sign the pension form (this is one of the best bits!). It would be good if all locums used it, as then it would be so much easier for me to track my bookings and check their availability without emailing or texting them, waiting for a reply and then emailing back to confirm. It’s a great place for their documents to sit also. I can access it from home or my mobile which is useful as when I am not in surgery is when I usually need a locum!"
