Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
1. The purpose of this study is to obtain genetic data on a well-defined population of patients with glaucoma that had accurate measurements of rates of structural and functional change over time. 2. The investigators aim to recruit 5,000 patients for Phase I and 100 patients for Phase II over a period of 2 years for obtaining blood samples which will be processed for extraction of DNA and genotyping. Phase II also includes eye examination. Patients will be selected from the Duke Glaucoma Registry (DGR) database and will be contacted by phone, mail or email using a standardized script and procedure. 3. Data analysis, based on patient-blind (no personal health information) data will take place at Duke and Genentech. No protected health information (PHI) will leave Duke. Standard statistical methods will be used to analyze the collected data and to develop predictive statistical models for fast progression in glaucoma. Risks from participating in the study are low and include loss of confidentiality and inherent issues related to drawing blood.
