Diabetic Retinopathy It is estimated that more than 2.5 million people worldwide are affected by diabetic retinopathy.

Diabetic retinopathy is the leading cause of vision loss in adults of working age (20 to 65 years) in industrialized countries.

Largely preventable

Prevention of Diabetic Retinopathy

Annual dilated eye examination

– Retinal lesions occur in up to 90% of individuals at 20 years

Glycemic control Limits risk of retinal disease, slows rate of

progression

Benefits observed in both Type 1 and Type 2 diabetes

Blood pressure control

Treatment of Diabetic Retinopathy

– Glucose control

– Blood pressure control

– Photocoagulation

Diabetes-related Kidney Disease

Diabetes is the largest cause of kidney failure in developed countries and is responsible for huge dialysis costs.

Type 2 diabetes has become the most frequent condition in people with kidney failure in countries of the Western world.

Cardiovascular Disease (CVD) in Diabetes*

Heart disease and stroke account for about 65% of deaths in people with diabetes.

Adults with diabetes have heart disease death rates about 2 to 4 times higher than adults without diabetes.

The risk for stroke is 2 to 4 times higher and the risk of death from stroke is 2.8 times higher among people with diabetes

Additional Therapies to Reduce Cardiovascular Disease

Encourage active lifestyle & healthy diet

Lower LDL cholesterol levels:

– Primary Prevention (CARDS study)

– Target LDL <100 mg/dL all individuals with type 2 diabetes

– If diabetes and CVD target LDL < 70 mg/dL

Control blood pressure <130/80 mmHg

Daily aspirin therapy

Vibration Sensation

• Vibration Detection/Perception Threshold has been shown to predict the development of foot ulcers1

• The tuning fork (128 Hz) is a practical tool to screen

vibratory sensation loss

Neurological ExamVibratory Sensation

Vibratory Sensation Testing

Help patient differentiate vibration vs. pressure Fork on unsupported DIP joint of 1st toe When vibration sensation on toe ceases, compare to

examiners distal forefinger in seconds If this is normal, no need to do monofilament test

Normal = 0-10 seconds

Abnormal = Greater than 10 seconds

Absent = No vibration sensed

Prevention is Essential!!

•Maintain good diabetes control•Practice good foot care habits•Check feet every day•Treat problems right away•Have regular health check-ups

Provide ongoing patient education

Good Foot Care Habits

Keep feet clean and dry

If skin is dry, use a lotion daily

Protect feet from hot and cold

Trim toenails weekly

Nail Care

• Trim after washing a drying feet

•Use a nail clipper (or nipper) and trim straight across

•Do not cut too short or cut into nail corners

•Have a podiatrist or foot specialist trim nails if the patient cannot see or reach their nails OR if fungal nails present

Good Foot Care Habits

Keep feet clean and dry

If skin is dry, use a lotion daily

Protect feet from hot and cold

Trim toenails weekly

Wear shoes and socks at all times

Appropriate Footwear

Wear shoes that fit well

Avoid open toed sandals, high heels and pointed toe shoes

Do not go barefoot especially if neuropathy present

Foot Self Inspection

Inspect feet daily

Check top and bottom of each foot, toes and nails and inside shoes

Use a mirror if unable to see feet well

Have someone check for you if unable

Contact doctor if concerns

Essentials of Foot Care

Comprehensive Foot Examination by HCP Annually– Patients with neuropathy - visual inspection of feet at every visit with

a health care professional

Advise patients to:– Inspect their feet daily

– Use lotion to prevent dryness and cracking (not between toes)

– File calluses with a pumice stone (no razors!)

– Cut toenails straight across or see podiatrist

– Always wear (natural fiber) socks and well-fitting shoes

– Notify their health care provider immediately if any foot problems occur
