Non-contact tonometry in the postoperative eye.

Non-contact tonometry in the postoperative eye.

The Keeler Pulsair non-contact tonometer was compared with the Goldmann applanation tonometer in a series of 48 eyes after operation. A correlation coefficient of 0.92 (p less than 0.001) was found between the two instruments, with the Pulsair having a statistically significant tendency to overread the Goldmann slightly in this situation. The Pulsair was, however, shown to be effective in the i...

Contact lens tonometry--application in humans.

PURPOSE To establish a standard clinical procedure for measuring intraocular pressure (Po) with the contact lens tonometer (CLT), to demonstrate possibilities for analyzing ocular pulsation and performing ophthalmodynamometry. METHODS A reliable histogram-based analyzing system for determining Po is used. First, the ocular pressure was registered with the CLT method and compared with the Gold...

Correction: Ocular Surface Displacement with and without Contact Lenses during Non-Contact Tonometry

PURPOSE To evaluate the displacement of the central ocular surface during non-contact tonometry with and without soft contact lenses and determine the factors associated with the displacement of the central ocular surface and intraocular pressure (IOP) reading changes caused by wearing soft contact lenses (CLs). METHODS One eye each in 21 subjects was studied. The cornea was photographed usin...

Non-contact eye-tracking on cats.

The objective of visual systems neuroscience has shifted over the past few years from determining the receptive fields of cells towards the understanding of higher level cognition in awake animals viewing natural stimuli. In experiments with awake animals it is important to control the relevant aspects of behavior. Most important for vision science is the control of the direction of gaze. Here ...
