In conjunction with scotometry, it gives the best indication of the success of medical control of conservative therapy.

It has been realized for some considerable time¹ that all forms of impression tonometry with the Schiøtz, McLean, or Gradle tonometers are far from reliable guides of the intraocular pressure, even when accurately standardized, because the indentation is influenced by variations in the scleral rigidity of normal human eyes and to a lesser degree by differences in corneal curvature.
