The EUA is scheduled as part of the routine clinical management of children with various ophthalmic conditions.
The RetCam is a pediatric wide-field retinal camera that has been the mainstay for pediatric ophthalmic imaging since 1997. Imaging using the RetCam (during the EUA) is conducted as part of routine clinical magagement.
The COSMOS images will be captured (during the EUA) after the RetCam images. The COSMOS is designed to be used in the same way as the RetCam, but to produce higher quality images.

Comparison of the field of view in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Field of view will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day
Comparison of the color in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Color will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day
Comparison of the dynamic range in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Dynamic range will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day
Comparison of the sharpness in RetCam and COSMOS images
Masked investigators will compare images from the RetCam and the COSMOS and grade sharpness on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day
Comparison of the detail in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Detail will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day

Comparison of the resolution in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Resolution will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
Time frame: 1 day
Comparison of the evenness of illumination in RetCam and COSMOS images
Masked investigators will review images from the RetCam and the COSMOS. Evenness of illumination will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
