Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Each individual will be thoroughly evaluated during the screening process to determine if they are suitable candidates for inclusion in any of the NEI ongoing studies. The screening evaluation will include past and current medical histories, and an appropriate physical examination. Other routine diagnostic procedures and tests may also be completed in order to help determine a subject's eligibility. These tests and procedures are of minimal risk and will be described in more detail in section III: "Study Procedures". Once the screening process is completed and their eligibility is assessed, the subjects will be informed of their options to participate in one or more of the current clinical research studies. If no appropriate protocol is identified, recommendations for other treatment options may be given to the individual, their primary doctor, or referring physician.
