7 | Diagnosis |
|
|
| We have individual diagnoses for various secondary open angle glaucoma due to: silicone oil, acute anterior uveitis, chronic anterior uveitis, intermediate uveitis, ocular surgery or laser, panuveitis, trauma, retinal detachment, siderosis, tumour infiltration. | Yes |
|
| 21928008 | We map our secondary open angle glaucoma diagnoses to the parent term 'secondary open angle glaucoma' in SNOMED, apart from for 'secondary open angle glaucoma (steroid induced)' for which there is a specific distinct code. |
|
| Alex Brown, Medisoft | EWooler - Questions 715144004 |Glaucoma caused by silicone oil (disorder)| is modelled as open angle. I can include this in the descriptions if there is also a closed angle version. 1285335004 |Open angle glaucoma due to ocular surgery (disorder)| exists with lateralised content. 1111391000000107 |Open angle glaucoma due to ocular trauma (disorder)| exists with lateralised content. 788948008 |Glaucoma due to retinal detachment (disorder)| exists but not modelled as open or closed. Is this always open? Can add if the group agree but do they all need open and closed angle versions? Glaucoma due to acute anterior uveitis - can this be closed as well as open angle? Glaucoma due to chronic anterior uveitis - can this be closed as well as open angle? Glaucoma due to intermediate anterior uveitis - can this be closed as well as open angle? Glaucoma due to ocular laser surgery - can this be closed as well as open angle? Glaucoma due to panuveitis - can this be closed as well as open angle? Glaucoma due to siderosis - can this be closed as well as open angle? How is glaucoma due to tumour infiltration different from 788947003 |Glaucoma due to intraocular neoplasm (disorder)| ? - IR 16/10/24 - am hoping most of these will be covered by our glaucoma work.

8 | Diagnosis |
|
|
| glaucoma suspect | Yes |
|
| 23986001 | SNOMED doesn't seem to offer 'glaucoma suspect' data items, so we currently map these to the non-suspect equivalent. Have found some reference in our old notes to a SNOMED code for glaucoma suspect but this doesn't seem to exist in my browser: 232079008 |
|
| Alex Brown, Medisoft | EWooler 26/02/24 232079008 |Glaucoma suspect (situation)| was inactivated and replaced with: 833278008 |Glaucoma suspect (disorder)| which also has 14 subtypes e.g. 1003488007 |Angle closure glaucoma suspect (disorder)|, 1003530008 |Glaucoma suspect caused by corticosteroid (disorder)|, 1003614009 |Open angle glaucoma suspect (disorder)|
|
| Completed as replacement concepts already exist. |
9 | Diagnosis |
|
|
| normal pressure glaucoma suspect | Yes |
|
| 50485007 | SNOMED doesn't seem to offer 'glaucoma suspect' data items, so we currently map these to the non-suspect equivalent. |
|
| Alex Brown, Medisoft | EWooler - Question. The current definition in SNOMED for 833278008 |Glaucoma suspect (disorder)| includes elevated IOP: At least 1 of these in 1 eye: optic nerve or nerve fiber layer suggestive of glaucoma; abnormal visual field consistent with glaucoma; an elevated IOP > 22 mm Hg. Can add if group agrees needed. - IR 16/10/24 - the current term is sufficient
|
|
|
10 | Diagnosis |
|
|
| primary juvenile glaucoma suspect | Yes |
|
| 71111008 | SNOMED doesn't seem to offer 'glaucoma suspect' data items, so we currently map these to the non-suspect equivalent. |
|
| Alex Brown, Medisoft | EWooler -Question This concept was in the earlier versions of the EGS Terminology and Guidelines for Glaucoma but is not in the latest version. Would be useful to understand why this is and if it should be added? - IR 16/10/24 - Congenital glaucoma will need input from someone with more experience in this
|
|
|
11 | Diagnosis |
|
|
| We have indivudal diagnoses for various congenital glaucomas: Broad thumb syndrome chromosomal abnormality | Yes |
|
| 204113001 | We map these congenital glaucoma diagnoses to the parent term 'congenital glaucoma' in SNOMED, there are child options of this term but not an exact match that we are aware of. |
|
| Alex Brown, Medisoft | Ewooler - Question Broad thumb syndrome is now referred to as Rubinstein-Taybi syndrome. We can add a concept for glaucoma in this syndrome if agreed by the group. Regarding chromosomal abnormalities is it possible to narrow these down to specific chromosome abnormality syndromes? - IR 16/10/24 - Congenital glaucoma will need input from someone with more experience in this
|
|
|
12 | Diagnosis |
|
|
| rubeotic glaucoma associated with central retina artery occlusion | Yes |
|
| 232086000 | We map this to the parent term 'neovascular glaucoma' in SNOMED. There are some child options in SNOMED but not for this specific cause. |
|
| Alex Brown, Medisoft | There is 1285643003 |Neovascular glaucoma due to central retinal vein occlusion (disorder)| which has a synonym of Rubeotic glaucoma due to central retinal vein occlusion. We could add an artery version if agreed by the group. |
|
|
13 | Diagnosis |
|
|
| risk of angle closure glaucoma | Yes |
|
| 314018004 | We map this to the parent term 'At risk of glaucoma' in SNOMED, which may be sufficient. |
|
| Alex Brown, Medisoft | 314018004 |At increased risk of glaucoma (finding)| and could add At increased risk of angle closure glaucoma. |
| Completed with anticipated release date 1 November 2024 |
14 | Diagnosis |
|
|
| closed angle glaucoma (intumescent lens) | Yes |
|
| 392300000 | I think this mapping is fine but not sure if there is scope for this to be added as an explicit synonym to SNOMED? |
|
| Alex Brown, Medisoft | Ewooler - Question Could add a synonym here if this is truly a synonym of 392300000 |Phacomorphic angle closure glaucoma due to disorder of lens (disorder)|. Though there is an existing concept - 95724003 |Intumescent cataract (disorder)| - IR 16/10/24 - synonym could be added to the current term (392300000)
|

|
15 | Diagnosis, Finding |
|
|
| no evidence of glaucoma no evidence of glaucoma or ocular hypertension | No |
|
| N/A | Assumed it was an editorial decision that SNOMED CT does not support negatives and these should be handled via qualifiers, however a handful of 'no evidence of…' findings exist relating to neoplasms. |
|
| Alex Brown, Medisoft | We do have 1109141000000102 |No evidence of glaucoma (situation)| with left and right versions. But you are correct that negation is out of scope for the terminology and software vendors are encouraged to store this in the information model. |
|
|
16 | Finding |
|
| is the natural formation of new blood vessels in the form of functional microvascular network, capable of perfusion of red blood cells, that form as collateral circulation in response to local poor perfusion or ischemia | Neovascularization | Yes | Retinal neovascularization (disorder)
