  Purpose

Background:

  • The relation between eye movement and brain function is a subject of interest to the National Eye Institute.
  • By comparing eye movement in healthy volunteers to research conducted on patients who have difficulty moving their eyes, the National Eye Institute hopes to develop and improve diagnostic procedures for people with eye diseases.

Objectives:

-The purpose of this study is to understand how we see visual patterns and how we move our eyes to see.

Eligibility:

  • Normal volunteers:

    • must have no serious illnesses and must be 18 years of age or older
    • who are 18 years of age or older must be willing to wear contact lenses that record eye movement.
    • individuals with a history of eye or brain diseases, or previous eye or eye muscle surgery, are not allowed to participate in this study. Individuals who are currently using eye medications also are not eligible for the study.
  • Patients:

    • who are 18 years of age or older must be willing to wear contact lenses that record eye movement.

Design:

  • Participants will visit the National Eye Institute outpatient clinic for examination and testing.
  • Participants will be screened with a medical history and eye examination (including eye pressure and eye movement tests).
  • Participants with healthy eyes will participate in eye movement testing experiments:

    • One or more sessions lasting less than three hours each.
    • Eye movements will be recorded with either a special contact lens or a video/infrared camera system.
    • For the majority of the studies done under this protocol, only one or two sessions will be required. A few studies recording very small eye movements will require three or more sessions.

Primary Outcome Measures:
  • Eye movement/responses to visual stimuli [ Time Frame: Ongoing ]

Estimated Enrollment: 100
Study Start Date: November 30, 2007
Detailed Description:
This natural history study will investigate eye movements and other responses to visual stimuli in normal individuals (normal volunteers) and patients. This protocol replaces a similar protocol (80-EI-0093) which served the same purpose. Normal adult volunteers will be recruited and will undergo an eye exam to assure that there are no visual system problems. Volunteers will be studied in one or more sessions where eye movement, verbal or hand movement responses are recorded in response to visual stimuli. Patients with diseases affecting the oculomotor or visual systems will also be recruited to help us better understand these systems and to help characterize their specific disease.
