1 | Diagnosis | superior or inferior hemi retinal vein occlusion | Yes | N/A | AB comment: 232043000 = Hemispheric retinal vein occlusion. Do you also want to request quadrants for BRVO? DH comment: Terms for superior HRVO and inferior HRVO desirable (as we have graphic entities that describe both). | David Haider | EWooler - Question: These can be added, but can I confirm the body structures where the occlusion occurs? In SNOMED we have:
superior hemi-retinal vein occlusion (70116008 + 39078001 ) inferior hemi-retinal vein occlusion (42578008 + 84228009 ) superior nasal retinal vein occlusion (70116008 ) superior temporal retinal vein occlusion (39078001 ) inferior nasal retinal vein occlusion (42578008 ) inferior temporal retinal vein occlusion (84228009 ) | |||||||||
2 | Diagnosis | Dome Shaped Maculopathy | No | N/A | I submitted a request for this, but it has not currently been accepted. Dec 2021 Update: My submission to SNOMED has now been accepted and new SNOMED code for DSM has now been created: 1366121000000108 | David Haider | complete | EWooler 26/02/24 This is a UK extension concept and not currently in the International release. I can request this is promoted from the UK extension. Though the PT would be Dome shaped macula with a synonym of Dome shaped maculopathy. | ||||||||
3 | Diagnosis | Partial thickness macular hole | Yes | 677921000119101, 677871000119105, 677971000119100, | There are codes for left, right and bilateral partial thickness macular hole, but no non-lateralised term like these is for most other diagnoses. Our workaround has been to use 312701008 to represent partial thickness / lamellar hole. But this term is slight different, and used for Stage 1 / Impending macular hole. The difference is small, but present. | David Haider | EWooler 26/02/24 This can be added. Will advise when completed. | Completed and release date 1 November 2024. | ||||||||
4 | Diagnosis, Finding | asymmetric optic disc cupping (anisoexcavation) | Yes | 12451000 | We map this to the generic 'Optic cupping' finding in SNOMED as we have not found a closer match. | Alex Brown, Medisoft | Completed with anticipated release date of 1 Dec 2024 | |||||||||
5 | Diagnosis | We have individual diagnoses for various secondary closed angle glaucoma due to: ROP, silicone oil, uveal effusion - increased choroidal venous pressure, uveal effusion - scleritis, uveal effusion - other, plateau iris, wound leak, aqueous misdirection, congenital anomaly, epithelial ingrowth, gas in vitreous, intraocular tumour, lens dislocation. | Yes | 21571006 | We map all of these secondary closed angle glaucoma diagnoses to the parent term 'secondary angle-closure glaucoma' in SNOMED. | Alex Brown, Medisoft | EWooler 26/02/24 Questions: Some of these exist 715144004 |Glaucoma caused by silicone oil (disorder)| including left, right and bilateral. But do not state open or closed. 15995591000119109 |Glaucoma of left eye due to plateau iris (disorder)| but again do not state open or closed. Congenital - currently editing content in this area as some existed but and modelled as congenital but without that word in the description so are being updated: Glaucoma due to congenital chamber angle anomaly - including left/right/bilateral 1231271005 |Glaucoma due to and following retinopathy of prematurity (disorder)| - no lateralised content yet. Does not currently state open or closed. Is it always closed angle? If the group can confirm the list to be added and if the current concepts are still relevant even though they do not state open or closed and we can add subtypes to these.

6 | Diagnosis | We have individual diagnoses for various secondary closed angle glaucoma due to tumours/cysts: ciliary body cyst iris cyst uveal effusion - tumour related | Yes | 27735002 | We map all of these secondary closed angle glaucoma diagnoses to the parent term 'Glaucoma associated with tumors AND/OR cysts' in SNOMED. | Alex Brown, Medisoft | EWooler - Questions: Existing 788947003 |Glaucoma due to intraocular neoplasm (disorder)| including left/right/bilateral. This is modelled as open angle. Is a closed angle version also required? 275477002 |Glaucoma due to ocular cyst (disorder)| including left, right and bilateral. Content also added for ciliary and iris cysts for release 1 July 2024 27735002 |Glaucoma associated with tumors AND/OR cysts (disorder)| does not now conform to editorial guidance so I would like to inactivate and replace pointing to replacements Existing 788947003 |Glaucoma due to intraocular neoplasm (disorder)| and 275477002 |Glaucoma due to ocular cyst (disorder)|

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)| ?

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.

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.

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?

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.
