Severity of diabetic retinopathy was graded according to the diabetic retinopathy Fukuda classification⁶ and mapped to the international classification for diabetic retinopathy (ICDR) using the Diabetic Retinopathy Clinical Practice Guideline from the Japanese Society of Ophthalmic Diabetology⁷.

Grading for arteriosclerotic changes in the retina from color fundus photographs based on the Scheie classification⁸, a clinical grading scale describing vascular narrowing and arteriovenous crossing changes.

Grading for hypertensive retinopathy changes in the retina from color fundus photographs grading based on the Scheie classification⁸, a clinical grading scale describing hemorrhages and other hypertensive signs.

Clinical recommendations provided by a medical professional after annual exam. Individual recommendations provided after evaluating results from a subject’s fundus image, visual field, visual acuity, hematology, blood pressure, lipids, glucose metabolism, immunity, liver function, lung function, uric acid, urinalysis, body mass index and hearing.

Recommendations are classified into seven categories. No abnormal findings were observed; Minor findings were noted, but they are not of concern; Subject must pay attention to lifestyle habits and monitor any changes in symptoms; Subject should receive regular health guidance from an occupational physician or public health nurse; A detailed examination at a medical institution is necessary for the findings indicated; Subject should follow their primary doctor’s instructions and continue treatment; A re-examination is needed for the findings indicated.

Hearing test results at four different frequencies: 500Hz, 1000Hz, 2000Hz, and 4000Hz.

Laboratory test results from blood or serum samples spanning biochemical, metabolic, immunological, and serological markers used to assess overall health, including lipid, metabolic, infectious disease, enzyme, kidney, and liver function.

Laboratory measurements assessing blood cell counts and morphology, including red and white blood cell parameters, differential leukocyte counts, hemoglobin indices, hematocrit, and platelet levels.

Measurements and indicators capturing body composition and anthropometrics, including weight, fat distribution and height-based metrics.

Ophthalmic assessments, including visual acuity, visual field and optic nerve head status.

Self-reported survey responses on marital status, average sleep, smoking status, alcohol consumption, medical history, surgical history, family history and medication status.

Urinalysis measurements evaluating kidney function, hydration status, and urinary abnormalities, including urine chemistry values, albumin, creatinine, and tests for the presence of blood, glucose, ketones, cells, casts, bacteria, and other indicators of urinary tract or metabolic conditions.

Physiological measurements of respiratory function and cardiovascular status, including spirometric measures of lung capacity and airflow, as well as pulse rate, and systolic and diastolic blood pressure readings.
