The retinal vasculature can be imaged and quantified using special dyes. This study will test whether the pattern of the retinal vasculature changes in patients with different levels of diabetic retinopathy can be quantified using computerized image analysis. In addition, the study will evaluate whether new drugs to treat diabetic retinopathy will be able to reverse these vascular changes.', 'detailedDescription': 'In this study, we are studying whether vascular density decreases during diabetic retinopathy prior to the pathological neovascularization seen in proliferative disease that results in blindness in more than 50 percent of patients, and whether the adverse, early vascular remodeling and neovascularization can be reversed by anti-angiogenic therapeutics. We have shown that vascular density decreases during early stages of diabetic retinopathy, prior to the pathological neovascularization that defines proliferative retinopathy, and that this change may be reversible with new anti-angiogenic therapeutics. To test this hypothesis we will determine (1) how blood vessels remodel and whether vascular density truly decreases during diabetic retinopathy and (2) how the anti-angiogenic steroid triamcinolone acetonide affects vascular density and pattern during human diabetic retinopathy and in our experimental model, the avian CAM model.\n\nTwenty patients (n = 20) for each of the 4 NPDR stages will be enrolled. In addition, a control group of 20 normal subjects will be recruited from the same clinical practice that do not have diabetes and no evidence of any vascular disease, for a total of 100 patients in the clinical trial.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n\\- Presence of mild, moderate, severe, or very severe non-proliferative diabetic retinopathy (defined as ETDRS level \\>10) in at least one eye (based on ETDRS criteria)\n\nExclusion Criteria:\n\n* Any condition that might impair the patient's ability to give informed consent\n* Any condition or media opacity that might impair the patient's ability to perform vision tests, color fundus photographs or fluorescein angiography\n* Severe allergy or other contraindication to sodium fluorescein dye\n* Participating in any other ophthalmic clinical trial"}, 'identificationModule': {'nctId': 'NCT00411333', 'briefTitle': 'Vascular Remodeling and the Effects of Angiogenic Inhibition in Diabetic Retinopathy', 'organization': {'class': 'NIH', 'fullName': 'National Eye Institute (NEI)'}, 'officialTitle': 'Vascular Remodeling and the Effects of Angiogenic Inhibition in Diabetic Retinopathy', 'orgStudyIdInfo': {'id': 'R01 EY017528-0'}, 'secondaryIdInfos': [{'id': 'R01EY017528', 'link': 'https://reporter.nih.gov/quickSearch/R01EY017528', 'type': 'NIH'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'triamcinolone acetonide (Kenalog)', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'locations': [{'zip': '44195', 'city': 'Cleveland', 'state': 'Ohio', 'country': 'United States', 'facility': 'Cole Eye Institute', 'geoPoint': {'lat': 41.4995, 'lon': -81.69541}}], 'overallOfficials': [{'name': 'Peter K Kaiser, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Cole Eye Institute'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'National Eye Institute (NEI)', 'class': 'NIH'}}}}
