Long Term Follow-Up of Diabetic Retinopathy Clinical Trials Facts presented on Clinical Trials Search is not designed to be a substitute for certified medical advice, travels to or professional assistance by using a genuine doctor. We aren't mDs. Always consult your physician about Long Term Follow-Up of Diabetic Retinopathy conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Long Term Follow-Up of Diabetic Retinopathy Clinical research trials and Long Term Follow-Up of Diabetic Retinopathy health trials occur in a lot of of cities throughout the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the potency of new does drugs. The role of the studies / undertakings is to figure out specific human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all sorts of conditions, including Long Term Follow-Up of Diabetic Retinopathy. Long Term Follow-Up of Diabetic Retinopathy Clinical Trials and other clinical trials permit volunteers to get medical treatment choices before they are available to the general public. Many times the test subjects get professional assistance for free of charge, and occasionally they are compensated for their time. Sometimes there is a cost for a Long Term Follow-Up of Diabetic Retinopathy clinical trial. Human subjects often get the best healthcare possible for their Long Term Follow-Up of Diabetic Retinopathy condition. Risks are a reality, nevertheless, and could include additional or frequent dr. calls, medical hazards (perhaps life-threatening), and/or the treatment being ineffectual. Trials are federally governed with exacting guidelines to protect clinical trials patients.

Long Term Follow-Up of Diabetic Retinopathy
For Condition: Blindness,Cataract,Diabetes Mellitus,Diabetic Retinopathy,Macular Degeneration
Status: Completed
Sponsor(s): National Eye Institute (NEI) ,
Synopsis: The efficacy of laser photocoagulation treatment for diabetic retinopathy has been demonstrated by several National Eye Institute (NEI) sponsored clinical trials. The Diabetic Retinopathy Study (DRS) demonstrated that scatter photocoagulation reduces the risk of blindness from diabetic retinopathy. The Early Treatment Diabetic Retinopathy Study (ETDRS) extended these findings by providing information on when to initiate scatter photocoagulation and by demonstrating that focal treatment was effective in treating macula edema. The Krypton Argon Regression Neovascularization Study (KARNS) showed that scatter photocoagulation with krypton red laser was just as safe and effective as the argon blue-green laser in the treatment of proliferative diabetic retinopathy. Unfortunately, there is little data on the long term effects of photocoagulation on visual function. The first objective of this study is to assess the long term effects of photocoagulation for diabetic retinopathy. A second objective is to provide additional information on the risk of progression of cataracts in persons with diabetes. All patients previously treated with laser photocoagulation (focal and/or scatter) are eligible to participate in this long term study. The first priority will be given to patients who participated in the ETDRS and KARNS because of the wealth of information available regarding the details of their treatment and course after treatment. Study evaluations will include a standard ophthalmic examination, fluorescein angiography, lens and fundus photography.
