In the EDQM the Intended sites are in a flat list with no hierarchy. Whilst ‘Ocular’ is an Intended site in EDQM, Intraocular, Intracameral and Intravitreal are not Intended sites in EDQM.
In EDQM Intraocular, Intracameral and Intravitreal are instead Routes of Administration.
The placing of these in a hierarchy is something SNOMED CT has done, and is not from EDQM.
I’d also note that we don’t exactly replicate EDQM. For example in SNOMED CT:
In EDQM the same ‘Pharmaceutical dose form’ has the EDQM characteristics:
The key difference here is in EDQM, it has an Intended site of ‘ocular’ but in SNOMED CT it has a Has dose form intended site of ‘intraocular’.
So we are already different from the EDQM model.
