Visual acuity
🟦 Long-term type 2 DM can cause diabetic retinopathy, cataracts, and glaucoma, leading to progressive vision loss.
🟦 Assessing visual acuity helps detect early decline and triggers referral for a dilated eye exam.
🟦 Vision changes may be subtle and develop gradually, so routine assessment is essential.
🟦 Early detection supports timely treatment to prevent permanent visual impairment.
🟦 Visual assessment is a direct screening for a major microvascular complication of diabetes.
Sensation in feet and legs
🟦 Diabetes commonly causes peripheral neuropathy, which reduces protective sensation in the lower extremities.
🟦 Loss of sensation increases risk for unnoticed injuries, ulcers, and infection.
🟦 Sensory testing (monofilament, light touch) identifies neuropathy early.
🟦 Detecting neuropathy supports preventive foot care and reduces risk for amputation.
🟦 This assessment targets a key long-term nerve complication of diabetes.
Skin condition of lower extremities
🟦 Diabetes can impair circulation and wound healing, increasing risk for skin breakdown and diabetic foot ulcers.
🟦 Inspecting skin identifies dryness, cracks, calluses, color changes, or open areas early.
🟦 Even small wounds can progress due to impaired healing and decreased sensation.
🟦 Early intervention prevents infection and severe tissue damage.
🟦 Skin checks support prevention of long-term vascular and neuropathic complications.
Serum creatinine and blood urea nitrogen (BUN)
🟦 Long-term DM can cause diabetic nephropathy, leading to declining kidney function.
🟦 Creatinine and BUN help assess renal filtration status and identify worsening kidney impairment.
🟦 Kidney damage may be present before symptoms appear, so lab monitoring is critical.
🟦 Abnormal results guide medication dosing, diet changes, and nephrology referral.
🟦 This assessment screens for a serious microvascular renal complication.
Signs of respiratory tract infection
🟦Infection monitoring is important, but it does not specifically evaluate long-term diabetic complications.
🟦It reflects acute illness risk rather than chronic neuropathy, retinopathy, or nephropathy.
