Identified from intial search terms outside of OpenCodelists: "visual" "vision" "diplopia" "blind" "amblyopia" "scotoma" "blur" "photophobia"

Clearly irrelevant codes excluded (with review by a second clinician)

Candidate codelist reviewed outside OpenCodelists by two clinicians. As we reviewed our candidate codelist outside openCodelists, we did not benefit from the tree structures that might have identified additional codes. However, we assume that these are likely to be codes that are not used frequently, e.g., eponymous syndromes.

Excluded visual disturbances due to clear cause (e.g., toxicity). Excluded amblyopia, as usually a developmental problem. Excluded codes related to abnormal visual screening tests as these are usually done in childhood and so may represent congenital or developmental problems. Excluded congenital problems (e.g., coloboma). Excluded disorders of visual pathways and central disorders. Excluded visual tests.
