The DCDC App is an experimental software application that is being developed at the University of Nebraska Omaha. The DCDC app will map and draw the visual distortions of patients with Age-related Macular degeneration.","overall_status":"Completed","phases":[],"study_type":"INTERVENTIONAL","sponsor":"University of Nebraska","enrollment":5,"countries":["United States"],"start_date":"2014-12-29","completion_date":"2016-06-01","last_update_date":"2023-09-06","source_url":"https://clinicaltrials.gov/study/NCT02337647","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
