Screening Study for the Evaluation and Diagnosis of Potential Research Subjects With Nystagmus or Strabismus
This screening protocol is designed to help recruitment patients for National Eye Institute
(NEI) studies on nystagmus and strabismus. 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 nystagmus or strabismus study. These include routine
laboratory tests, non-invasive imaging, questionnaires, and other standard tests. If needed,
a test called oculography may be done to record eye movements. There are two procedures for
recording and documenting these movements. In the infrared system, the patient wears a pair
of glasses or goggles and looks at a red light while the head is kept steady. In the search
coil system, the eye is numbed with anesthetic eye drops and a soft contact lens is placed
on the eye. Then the patient looks at a red light while the head is held still. Each
oculography session lasts 20 to 30 minutes. Photographs of the eye may be taken.
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.

This protocol is designed for the screening of patients with either diagnosed or undiagnosed
conditions, and serves as a first step for individuals who may be eligible and wish to
participate in National Eye Institute (NEI) clinical research studies.
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. Once
the screening process is completed and their eligibility 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.

- INCLUSION CRITERIA
Inclusion and exclusion criteria vary with the particular protocol for which a patient is
being screened.
In addition to those diagnoses currently under study, subjects with unusual, interesting,
or unknown conditions that require the establishment of a diagnosis may be eligible for
inclusion in this study.
