| ID | Type of data (e.g. diagnosis, finding, procedure) | Date reported | Originally reported by | Definition (including details of the body structure(s) involved if not obvious from the name) | Description of data | Is there a SNOMED code which is related but does not sufficient | Existing SNOMED CT code | Any other terminology or classification where the term exists | If so, details | Any other info | Suggestion/proposal - Ideas of the best way this issue could be addressed | Peer-reviewed reference(s) to support proposal (published within last 10 years) | Author of log | Reported to SNOMED (dated and details) | Named and dated updates | Resolved (dated and method of resolution) |
| 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 | ||||||||||
| 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 | |||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
| 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 | ||||||||||
