Mirror-Exophthalmometer

 

The instrument is use to measure the height from the eyeball vertex corneae to the margo orbitalis.

The product can precisely measure the level of exophthalmia over the orbital margins, on the principal basis that both vertexes of cornea and scaleplate are projected to the front of prism by total reflection on the bevel, with the special structure of the isosceles right-angled triangle prism.
