'To rub or not to rub' - if you mention this in our professional field, everybody automatically starts talking about care systems. And while the general opinion on that issue pretty much has been set to 'rub', it seems that the discussion on whether eye-rubbing is related to the development of keratoconus remains in debate. Many in clinical practice report that eye rubbing and keratoconus are related: but is it a cause or a symptom? Certainly, about half of the keratoconic population appears to be atopic. But is that proof? Charles McMonnies wrote a thorough trilogy-review on the subject in three different peer reviewed journals covering Abnormal rubbing and keractasia (CLAO Journal), Mechanisms of rubbing-related trauma in keratoconus Mechanisms of rubbing-related trauma in keratoconus (Cornea) and Behaviour modification of chrinic habits of abnormal eye rubbing (CLAE). If eye-rubbing proves to be a valid theory, treatment of allergies and atopic conditions seems advised, and mabye non-steroidal anti-inflammatory drugs should be suggested for our keratoconus patients?

 

 
..than a thousand words. Javier González-Cavada from Madrid, Spain has produced a 70-picture (R)GP chart with all kinds of different (R)GP lens fits. It's a fantastic resource for teaching and training that covers anything from lens fits (flatter - steeper) to post-surgical fitting, orthokeratology and different complications.

The poster text is in Spanish, but for those of us who do'nt understand that - a picture tells more than a thousand words. Or, in Spanish: "Una imagen vale más que mil palabras".
