Overview

Diabetic Retinopathy
Diabetic retinopathy is an eye condition caused by damage to the small blood vessels in the retina after prolonged or poorly controlled diabetes. It may begin without noticeable symptoms and can progress to blurred vision, floaters, bleeding, retinal detachment, or vision loss. Regular eye examinations can detect retinal changes early and help prevent severe vision problems.
Hepatitis C
Hepatitis C is a liver infection caused by the hepatitis C virus. It is transmitted primarily through contact with infected blood. Many people have few or no symptoms at first, but persistent infection can cause liver inflammation and, over time, serious complications such as cirrhosis or liver cancer. Acute hepatitis C may cause fatigue, nausea, abdominal discomfort, dark urine, or yellowing of the skin and eyes, although many people have no obvious symptoms. Some infections clear without treatment, while others become chronic. Chronic hepatitis C can progressively damage the liver if it remains untreated.

Diagnosis

Diabetic Retinopathy
Diabetic retinopathy is diagnosed through a comprehensive eye examination. An eye specialist examines the retina and optic nerve for leaking blood vessels, swelling, abnormal vessel growth, and other retinal changes. Dilated retinal examination, retinal photography, optical coherence tomography, and sometimes fluorescein angiography may be used to assess the severity and guide treatment.
Hepatitis C
Hepatitis C is diagnosed with blood tests. An antibody test can show whether a person has been exposed to the virus, while an HCV RNA test confirms whether active infection is present. Additional blood tests and liver assessment help evaluate liver health and the extent of disease. Testing generally begins with an HCV antibody blood test. If antibodies are detected, an HCV RNA test determines whether the virus is currently present. Further assessment may include liver enzyme tests, blood counts, fibrosis assessment, and imaging or other investigations when needed to evaluate liver damage and complications.

Prevention

Diabetic Retinopathy
The risk of diabetic retinopathy can be reduced by keeping blood glucose, blood pressure, and cholesterol within recommended ranges. Regular comprehensive dilated eye examinations are important even when vision seems normal. Taking prescribed diabetes medicines, following recommended lifestyle measures, avoiding smoking, and promptly addressing changes in vision can help reduce the risk of severe retinal damage and vision loss.
Hepatitis C
Hepatitis C can be prevented by avoiding contact with infected blood. Do not share needles, syringes, razors, or other items that may contain blood. Use properly sterilized medical and tattoo equipment and follow appropriate precautions when there is a risk of blood exposure. There is currently no widely available vaccine for hepatitis C. Prevention therefore depends on reducing blood exposure, using sterile injection and medical equipment, and ensuring appropriate infection-control practices. People with ongoing exposure risks should discuss testing and prevention strategies with a healthcare professional.

Risk Factors

Diabetic Retinopathy
Risk factors include having diabetes for many years, consistently high blood glucose levels, high blood pressure, abnormal cholesterol levels, pregnancy in someone with diabetes, smoking, and kidney disease. The risk generally increases as diabetes continues over time. Poor control of blood glucose, blood pressure, and cholesterol can accelerate retinal blood-vessel damage.
Hepatitis C
Risk factors include sharing needles or other injection equipment, receiving medical care with inadequately sterilized equipment, having a blood transfusion or organ transplant before modern screening was introduced, and other exposures to infected blood. Risk can also increase with certain sexual or occupational exposures. People who inject drugs or share injection equipment have an important risk of blood exposure. Other risks include accidental exposure to infected blood, nonsterile tattooing or piercing equipment, and certain healthcare exposures. People with previous transfusions or transplants before routine HCV screening may also have increased risk.
