Abstract

Ophthalmic imaging devices and related methods employ self-alignment of a user with an optical axis of the imaging device. An ophthalmic imaging device includes an imaging assembly having an optical axis, a housing assembly, and a viewer assembly. The housing assembly is configured to rest on a horizontal surface during operation of the imaging assembly. The optical axis is oriented at an angle from 45 degrees to 85 degrees from the horizontal surface. The viewer assembly includes an interface surface shaped to engage a user's head to stabilize a position and an orientation of the user's head relative to the optical axis. The viewer assembly accommodates different positions and/or orientations of the user's head relative to the optical axis so as to enable alignment, by the user, of one of the user's eyes with the optical axis.
