Systems and methods for alignment of the eye for ocular imaging

An ocular alignment system for aligning an optical axis of a subject’s eye with an optical axis of an ocular imaging device comprising:

• a tubular housing having a first end, a second end, an outer surface, and an inner surface, wherein the inner surface defines a luminal space
• a plurality of guide lights positioned around the optical axis of the ocular imaging device;
• and
• one or more baffles configured to mask the plurality of guide lights from view of the subject such that the plurality of guide lights are unmasked to the subject when the optical axis of the subject’s eye is aligned with the optical axis of the ocular imaging device and are otherwise masked,
• wherein each guide light assembly of a plurality of guide light assemblies comprising the plurality of guide lights further comprises:
• a body comprising a first side and a second side opposite the first side, wherein the second side faces the luminal space;
• and
• a channel defined in the body, wherein the channel extends from the body first side to the body second side, wherein the channel forms an opening in the body second side, wherein the guide light is disposed within the channel and configured to emit light out of the opening, and wherein the one or more baffles is disposed transversely in the channel between the guide light and the opening.

A method of aligning a subject’s eye with an optical axis of an ocular imaging device comprising:

• providing a plurality of guide lights around an optical path between the subject’s eye and the ocular imaging device;
• and
• providing a plurality of baffles comprising a first set of the baffles configured to mask the plurality of guide lights from view of the subject such that the plurality of guide lights is unmasked to the subject when the eye of the subject is aligned with the optical axis of the ocular imaging device and such that the plurality of guide lights is otherwise masked,
• wherein the ocular imaging device comprises a tubular housing having a first end, a second end, an outer surface, and an inner surface, wherein the inner surface defines a luminal space;
• wherein each guide light assembly of a plurality of guide light assemblies comprising the plurality of guide lights further comprises:
• a body comprising a first side and a second side opposite the first side, wherein the second side faces the luminal space;
• and
• a channel defined in the body, wherein the channel extends from the body first side to the body second side, wherein the channel forms an opening in the body second side, wherein the guide light is disposed within the channel and configured to emit light out of the opening, and wherein the baffle is disposed transversely in the channel between the guide light and the opening.
