1. An eye examination apparatus to inspect a vitreous humor of an eye, comprising:
a probe; wherein the probe, includes:
a shaft including a distal end;
a camera disposed at the distal end, wherein the distal end and the camera are configured to be inserted into the vitreous humor; and
a magnetic orientation sensor disposed at a section of the shaft, wherein signals generated by the magnetic orientation sensor are used at least to compute roll values of the shaft;
a display; and
a processing circuitry;
wherein the processing circuitry is configured to:
receive respective signals from the magnetic orientation sensor while the shaft is twisted to respective orientations;
compute respective roll values of the shaft at the respective orientations responsively to the respective received signals;
output a notification responsively to at least one of the computed roll values; and
render to the display respective images captured by the camera of respective inside portions of the eye.
