ABSTRACT:
A head mounted lens support for performing examination and photography of the posterior structures of the eye. The support includes a lateral support to which a pair of adjustable earpieces, and an adjustable nosebridge are attached. Right and left lens positioners are moveably and pivotable attached to the lateral support. The lens positioners each are adjustable by lateral positioners, depth positioners, and angle positioners. The angle positioners swivel from their nominal positions, perpendicular to the lateral support, through an arc of approximately 25 degrees in order to allow full examination of the structures in the posterior chamber of the eye. Right and left lens cradles are attached, respectively, to the ends of the right and left angle positioners. The lens cradles are forms of arc clamps which receive a lens sleeve. The lens sleeve is itself an arc clamp which contains the actual lens.
