    2. 2. Diabetic Eye Disease in Indiana <ul><li>Over 112,000 people in Indiana alone have diabetic retinopathy. </li></ul><ul><ul><li>That’s ~20% of diabetics. </li></ul></ul><ul><li>In Indiana, ~60% of diabetics receive an annual eye exam. </li></ul><ul><li>Each year - ~12,000 – 24,000 new cases of blindness. </li></ul>
    3. 3. Diabetes in Indiana
    4. 4. Diabetic Retinopathy in Indiana
    5. 5. Where does it affect the eye? <ul><li>Lens: variations in blood sugar can cause variations in the power of the lens. Uncontrolled diabetics are prone to intermittent blurry vision. </li></ul><ul><li>Retina: Diabetic Retinopathy is when the eye’s blood vessels become leaky and can ultimately bleed profusely. </li></ul>
    6. 6. Ocular Symptoms <ul><li>Blurred Vision- As the power of the lens changes, patients experience unstable blurred vision that fluctuates over weeks to months. </li></ul><ul><li>Diplopia- Retinal (macular) edema can produce a myriad of optical nuances. </li></ul><ul><li>Vision Loss- If retina is damaged, vision can be lost permanently. </li></ul>
    7. 7. When does Diabetes start affecting the Eye? <ul><li>Two determining factors: </li></ul><ul><ul><li>Blood Glucose Control </li></ul></ul><ul><ul><li>Duration of Diabetic Status </li></ul></ul><ul><ul><ul><li>As childhood obesity increases, type 2 diabetes begins earlier. </li></ul></ul></ul>

    46. 47. Questions??? <ul><li>POP QUIZ!!! </li></ul>
    47. 48. QUIZ #1 True or False <ul><li>People with diabetes are more likely than people without diabetes to develop certain eye diseases. </li></ul><ul><li>True. Diabetic eye disease includes diabetic retinopathy—a leading cause of blindness in adults—cataract, and glaucoma. The longer someone has diabetes, the more likely he or she will develop diabetic eye disease. </li></ul>
    48. 49. #2 True or False <ul><li>Diabetic eye disease usually has early warning signs. </li></ul><ul><li>False. Often there are none in the early stages of the disease. Vision may not change until the disease becomes severe. </li></ul>
    49. 50. #3 True or False <ul><li>People with diabetes should have yearly eye examinations. </li></ul><ul><li>True . Everyone with diabetes should get an eye examination through dilated pupils at least once a year. Because diabetic eye disease usually has no symptoms, regular eye exams are important for early detection and timely treatment. </li></ul>
    50. 51. #4 True or False <ul><li>Diabetic retinopathy is caused by changes in the blood vessels in the eye. </li></ul><ul><li>True . In some people, blood vessels in the retina may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. </li></ul>
    51. 52. #5 True or False <ul><li>People with diabetes are at low risk for developing glaucoma. </li></ul><ul><li>False. Glaucoma is almost twice as likely to occur in people with diabetes than in those without the disease. Glaucoma can usually be treated with medications or laser or other surgery. </li></ul>
    52. 53. #6 True or False <ul><li>Laser surgery can be used to halt the progression of diabetic retinopathy. </li></ul><ul><li>True. In laser surgery, a special beam of light is used to shrink the abnormal blood vessels or seal leaking blood vessels. Laser surgery has been proved to reduce the five-year risk of vision loss from advanced diabetic retinopathy by more than 90 percent. </li></ul>
    53. 54. #7 True or False <ul><li>People with diabetes should have regular eye examinations through dilated pupils. </li></ul><ul><li>True. An eye examination through dilated pupils is the best way to detect diabetic eye disease, in which drops are used to enlarge the pupils. This allows the eye care professional to see more of the inside of the eye to check for signs of the disease. </li></ul>
    54. 55. #8 True or False <ul><li>Cataracts are common among people with diabetes. </li></ul><ul><li>True. People with diabetes are twice as likely to develop cataracts and to develop them at an earlier age than are those without diabetes. Cataracts can usually be treated with surgery. </li></ul>
    55. 56. #9 True or False <ul><li>People who have good control of their diabetes are not at high risk for diabetic eye disease. </li></ul><ul><li>False. Even with good control of blood glucose, there is still a risk of developing diabetic eye disease. However, studies show that careful management of blood sugar levels slows the onset and progression of diabetic retinopathy. </li></ul>
    56. 57. #10-- True or False <ul><li>The risk of blindness from diabetic eye disease can be reduced. </li></ul><ul><li>True. With early detection and timely treatment, the risk of blindness from diabetic eye disease can be reduced. </li></ul>
