Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will determine whether certain factors in the blood are associated with the severity of diabetic retinopathy. Patients age 10 years and older with diabetes mellitus and diabetic retinopathy may be eligible for this study. Those enrolled will represent a range of diabetic retinopathy from minimal to severe. Participants will undergo the following procedures: * medical history * thorough eye examination * photographs of the eye * blood tests to measure blood lipids (cholesterol and triglycerides) and serum creatinine (for kidney function) * blood tests to measure levels of blood factors (cell adhesion molecules, chemokines and vascular endothelial growth factor) that may be related to the progression of diabetic retinopathy * blood pressure measurement * urinalysis This study may lead to a better understanding of how diabetic retinopathy develops and progresses.
