1. A device for aligning a subject's eye with an optical axis of an ocular imaging device comprising:
a. a tubular housing defining a luminal space configured to allow for passage of the optical axis therethrough; and
b. a plurality of guide light assemblies mounted to the housing around the luminal space, each guide light assembly comprising:
a guide light; and
a baffle configured to mask light from the guide light, wherein the baffle further comprises a slit configured to allow passage of light along a path of ocular alignment,
wherein the light from each of the plurality of guide light assemblies is visible to the subject when the subject's eye is in alignment with respect to the optical axis of the ocular imaging device and not visible when the subject's eye is out of alignment with respect to the optical axis of the ocular imaging device.
