Figure 1. Representative images of the automated Goldmann Applanation Tonometry (GAT) technique.
(A) The camera system set up on a slit lamp microscope. (B) Unlabeled frames from automated GAT video recordings. (C) Labeled frames with the tonometer tip (outer white circle) and 2 mires (smaller white circles) outlined. Because the size of the mire at a set force is what is being measured, no adjustment of mires for overlap is performed.
