| Concept | Classification of age related macular degeneration |
|---|
| Description | Classifies the condition and argues the diagnostic decision for age-related macular degeneration. |
|---|
| Use | Provide details about grading or staging of age-related macular degeneration. It is useful to specify the overall diagnoses provided using the "problem/diagnosis" archetype. |
|---|
| Purpose | Register the stage of age-related macular degeneration for a patient at a given time. |

| AMD classification | AMD classification: Clinical grade determined for age-related macular degeneration.
- at0005::No AMD [No or a few (<5) small drusen (<63 micrometres in diameter).]
- at0006::Early AMD [Many small drusen or a few intermediate-sized (63-124 micrometres in diameter) drusen, or macular pigmentary changes.]
- at0007::Intermediate AMD [Extensive intermediate drusen or at least one large (≥125 micrometres) drusen, or geographic atrophy not involving the foveal centre.]
- at0008::Dry advanced AMD atrophic [Geographic atrophy involving the foveal centre.]
- at0009::Exudative or wet AMD [Choroidal neovascularisation or evidence for neovascular maculopathy (subretinal haemorrhage, serous retinal or retinal pigment epithelium detachments, lipid exudates, or fibrovascular scar).]
[SNOMED-CT::414173003 | Exudative age-related macular degeneration] - at0021::Ungradable [Patient ungradable due to the low quality of acquisitions or uncertainty of the evaluator.]
[SNOMED-CT::408313004 | O/E - non-referable retinopathy]
|
|---|
| Diagnostic criteria | Diagnostic criteria: Clinical findings supporting the diagnose or grading.
- at0010::Small drusen [Drusen < 63 µm in diameter.]
- at0011::Intermediate drusen [Drusen 63-124 µm in diameter.]
- at0012::Numerous intermediate drusen [More than x drusen 63-124 µm in diameter.]
- at0013::Large drusen [Drusen ≥125 µm in diameter.]
- at0014::Geographic atrophy [A sharply demarcated, usually round or oval, area of atrophy of the RPE not involving the center of the fovea.]
- at0015::Geographic atrophy involving foveal center [Geographic atrophy of the RPE involving the foveal center.]
- at0016::Choroidal neovascularization (CNV) [Pathologic angiogenesis originating from the choroidal vasculature that extends through a defect in Bruch's membrane.]
- at0017::Serous or hemorragic detachment [Serous or hemorragic detachment of the neourosensory retina or RPE.]
- at0018::Retinal hard exudates [Hard exudates resulting from chronic intravascular leakage.]
- at0019::Fibrovascular proliferation [Subretinal and sub-RPE fibrovascular proliferation.]
- at0020::Disciform scar (subretinal fibrosis) [Subretinal fibrovascular tissue that usually becomes more fibrous within a few years and that is often the end result of CNV.]
