Official title

Evaluation and Treatment Protocol for Potential Research Participants With Inherited Ophthalmic Diseases

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will evaluate potential candidates for future clinical research studies related to diagnosed or undiagnosed genetic eye disorders or diseases. It will not test any new treatments, but it may arrange for standard treatments for existing eye disorders. The purpose of the study is to train eye doctors and medical researchers at the National Institutes of Health in appropriate methods and procedures for treating patients with genetic eye diseases, and to expand the pool of possible participants for future research studies and trials on eye health. Volunteers for this study may be adults and minor children who have been diagnosed with or are at risk for having a genetic eye disease. Candidates may not have any other medical conditions that would interfere with the researchers' ability to perform the examinations and procedures required for this study. Participants will give a complete medical and family history and undergo a series of tests and procedures as part of this research study. The procedures include a full eye examination and vision testing, electrooculography and an electroretinogram to examine the function of the retina, and flourescein angiography to provide information on the flow of blood in the participant's eyes. Participants will provide research material for further studies by giving a blood sample to be held for genetic testing and analysis, and adult participants will also undergo a skin biopsy to provide cell tissue for additional research material. At each clinic visit, participants will receive treatment for their genetic eye disease as needed, including medications or surgical procedures. Participants may remain a part of this study for up to three years.
