We have had a member query regarding this concept.  

Can you please review the modelling of this concept as it is currently modelled as a 'separation' and a descendant of 'detachment' whereas other tears are modelled as 'ruptures'


There is also another concept in the same hierarchy 247158001 |Macular pigment epithelial detachment (disorder)| modelled the same way.  I am struggling to find any reference to 'macular pigment epithelial rip' but if rip is synonymous with tear then it would be correct to model with 125671007 |Rupture (morphologic abnormality)| such as for 95690009 |Retinal tear (disorder)|.  RPE detachment is modelled with 16640008 |Separation (morphologic abnormality)|.  As I can't find references to this rip, I am unsure if this is a tear or hole in the macula caused by RPE detachment, RPE detachment in the macular area or something else entirely but it looks like the concept needs improvement or inactivation if ambiguous.

It's an old concept that dates back to 1995 from NHS CV3.

I would appreciate your views.
