ADJUSTABLE DEVICE FOR VISION TESTING AND THERAPY

摘要

An adjustable and foldable device (100) for visual field testing or treatment includes a computer display (104r) mounted on a base (106) and presents visual stimuli to the patient. An associated head support assembly (105) with a chinrest (102) supports and positions the head of the subject with respect to the display. An articulated arm (110) joins the base and the head support assembly. The arm will resist a given downward force supplied by the head, and is foldable toward the display to create a more compact and portable device. Additional articulations may allow the head support assembly to fold upon arm, and the arm to fold upon the base. The device may include a locking mechanism that secures the device in a folded or unfolded configuration.
