  1. 1. DIABETIC RETINOPATHY PRESENTED BY:KUSHAL KAPOOR B-TECH (IT) 1147413018
  2. 2.  Diabetic retinopathy  Diabetic retinopathy epidemology  Risk factors  Diagnosing diabetic retinopathy  Stages of diabetic retinopathy  Diabetic retinopathy treatment  Prevention  conclusion
  3. 3. DEFINITION: PROGRESSIVE DYSFUNCTION OF THE RETINAL BLOOD VESSELS CAUSED BY CHRONIC HYPER GLYCEMIA.
  4. 4.  DR can be a complication of diabetes type 1 or diabetes type 2.  Initially DR is asymptomatic , if not treated though it can cause low vision or blindness.
  5. 5.  After 20 years of diabetes ,nearly 99% of patients of type 1 diabetes and 60%of type 2 have some degree of diabetic retinopathy.  33% of patients with diabetes have signs of diabetic retinopathy.
  6. 6. PREVALENCE OF DIABETIC RETINOPATHY AFTER 20 YEARS OF DIAGNOSIS
  7. 7.  RISK FACTORS OF DIABETIC RETINOPATHY ARE:- •HIGH BLOOD SUGAR •HYPERTENSION •HYPERLIPIDEMIA
  8. 8.  DIABETES CAN CAUSE VISION IN BOTH EYES TO CHANGE EVEN IF YOU DO NOT HAVE RETINOPATHY  RAPID CHANGES IN BLOOD SUGAR LEVEL ALTER THE SHAPE OF YOUR EYES LENS AND THE IMAGE ON THE RETINA WLL BECOME OUT OF FOCUS  YOU CAN REDUCE EPISODES OF BLURRED VISION BY MAINTAINING GOOD CONTROL OF YOUR BLOOD SUGAR
  9. 9.  PEOPLE WITH DIABETES SHOULD SEE THEIR OPTHALMOLOGIST IMMEDIATELY IF THEY HAVE HAVE VISUAL CHANGES THAT:-  AFFECT ONLY ONE EYE.  LAST MORE THAN A FEW DAYS.  ARE NOT ASSOCIATED WITH A CHANGE IN BLOOD SUGAR
  10. 10. Having difficulty with fine details (e.g. when reading or watching television)  Having difficulty in outdoor travel.  Experiencing visual fluctuation from hour to hour or day to day.  Seeing images as rippled (e.g. straight lines appears bent).  Experiencing blurred ,hazy or double vision.  Losing some visual fields.  Having difficulty seeing at night , or at low light.  Being particularly sensitive to glare and light.  Having difficulty focussing. 
  11. 11.  1. Mild Nonproliferative Retinopathy  2.Moderate Nonproliferative Retinopathy  3. Severe Nonproliferative Retinopathy  4.proliferative Retinopathy
  12. 12.  This happens when the tiny blood vessels of the retina begin to swell.  Characteristics: Microanuerysms only
  13. 13. NO RETINOPATHY
  14. 14. MILD PROLIFERATIVE DIABETC RETINOPATHY
  15. 15. Characteristics: Microaneurysms  Hard exudates  Flamed shaped hemorrhage  Damage to the blood vessel growth.
  16. 16. MODERATE NON-PROLIFERATIVE DIABETIC RETINOPATHY HARD EXUDATES MICROANUERSMS
  17. 17. Any of the following:     More than 20 intraretinal hemorrhage in each of four quadrants Definite venous beading in two or more quadrants Prominent Intraretinal Microvascular Abnormalities (IRMA) in one or more quadrants And no signs of proliferative retinopathy
  18. 18.  Blood supply is blocked causing the need to signal the need for new blood vessels
  19. 19. SEVERE NON-PROLIFERATIVE DIABETIC RETINOPATHY VENOUS BEADING
  20. 20.  The retina sends signals so new blood vessels are created . These blood vessels are abnormal and more likely to hemorrhage due to the thin walls of the blood vessels . The walls of these blood vessels are weak and soon became to haemorrhage.
  21. 21. characteristics: Neovascularization  Vitreous hemorrhage
  22. 22. Proliferative diabetic retinopathy
  23. 23.  Treatment of diabetic retinopathy The best measure for prevention of loss of vision from diabetic retinopathy is strict glycemic control
  24. 24.  Once Dr threatens vision treatment can include:Laser therapy to seal leaking blood vessels (focal laser) Laser therapy to reduce retinal oxygen demand (scatter laser) Surgical removal of blood from the eye (vitrectomy)
  25. 25. 90 PERCENT OF DIABETIC EYE DISEASE CAN BE PREVENTED SIMPLY BY REGULAR EXAMINATION ,TREATMENT AND BY CONTROLLING BLOOD SUGAR
  26. 26. CONT:PRIMARY PREVENTION  STRICT GLYCEMIC CONTROL BLOOD PRESSURE CONTROL SECONDARY PREVENTION ANNUAL EYE EXAMS TERTIARY PREVENTION RETINAL LASER PHOTOCOAGULATION VITRECTOMY
  27. 27. Diabetic retinopathy is preventable through strict glycemic control and annual dilated eye exams by an opthalmologist
