Screening for Studies on Inherited Eye Diseases

This screening protocol is designed to help recruit patients for National Eye Institute (NEI) studies on inherited eye diseases. Patients must meet specific requirements of a research study, and this protocol serves as a first step for admitting patients to an appropriate program. Candidates will undergo a medical history, physical examination, eye examination and blood test. The eye examination includes measurement of eye pressure and dilation of the pupils to fully examine the lens, vitreous and retina. Specialized tests will be done only if needed to determine eligibility for a specific study in NEI's Ophthalmic Genetics Clinic. These include routine laboratory tests, non-invasive imaging, questionnaires and other standard tests, as well as specialized tests and procedures where needed, including genetic testing. Photographs of the eye may be taken. Patients will be asked questions about family history, especially relating to eye disease or cataracts, and a family tree will be drawn. A blood sample will also be drawn. When the screening is completed, patients will be informed of their options to participate in a study. Patients who are ineligible for a current study will be informed of alternative treatments or options. No treatment is offered under this protocol.
