Brief Summary
Young children age 6 month to 6 years are often not able to cooperate for advanced OCT eye imaging. The purpose of this study is to investigate the use of a novel long-working distance swept source (SS) optical coherence tomography imaging system with fixation alignment for use first in young adults, older children, and then young children ages 6 months to 6 years. The investigator's future goal is to obtain important retinal and optic nerve information from OCT in clinic in these young children.

Outcome Measures
Primary Outcomes (1)
Percent of eyes with successful research imaging.
The primary outcome of this study is the percent of eyes with successful research imaging of retinal and optic nerve microanatomy including the following: the inner surface and retinal pigment epithelial (RPE) layers of the macula, a full cross section of optic nerve, identification of either foveal center or severe pathology that obscures foveal depression and the presence or absence of 5 substructures of retina (Inner retinal complex, inner nuclear layer, outer plexiform layer, photoreceptor layer, RPE layer).
1 year
Secondary Outcomes (3)
Percent of eyes with 5 substructures of retina capable of being determined as deformed, containing cystoid spaces or abnormal (> 50%) thickening or thinning of layers.
1 year
Participant feedback, as measured by questionnaire.
1 year
The time it takes to gather the research images.

Interventions
The long-distance SSOCT system designed by Duke University Biomedical Engineering Department allows the user to quickly image an eye at a much greater distance (typically 20-40 cm away but this could be longer or shorter). This could potentially be used while briefly attracting a child's attention to an illuminated image over the imaging lens. With this methodology, young patients would not need to place their eye close to the system and could be rapidly imaged during the short interval while they glance at the image from the correct distance.
