Patients will have mydriatic eye drops applied to dilate pupils for digital retinal photography/direct fundus examination; while awaiting mydriasis, they will undergo other care processes carried out by a well‐trained nurse, including foot/neuropathy screening; DN4 questionnaire to diagnose painful‐DPN; anthropometric measurement (weight and blood pressure); and biochemical testing (serum HbA1c, lipid profile, and renal function and urine albumin creatinine ratio). The gene discussed is ALB; the disease is neuropathy.
