1. A gonioscope comprising:
a gonioscopic optical element that includes:
a concave distal surface configured to be positioned on an eye of a subject; and
a proximal surface, wherein the gonioscopic optical element is configured to receive light from a structure inside the eye through the distal surface, and to output the light from the proximal surface to produce an image of the structure inside the eye, and wherein the proximal surface is angled relative to the distal surface so that a distance between the proximal surface and the distal surface on a first side of the gonioscopic optical element is smaller than a distance between the proximal surface and the distal surface on a second side of the gonioscopic optical element;
a handle coupled to the gonioscopic optical element, wherein the gonioscopic optical element has a plane of symmetry, and wherein the handle has a centered position with the handle extending generally upward from the gonioscopic optical element along the plane of symmetry; and
a plurality of arms extending distally from the gonioscopic optical element, wherein the plurality of arms have retention elements configured to engage scleral tissue of the eye to retain the gonioscope relative to the eye.
