Abstract
- To evaluate the clinical usefulness of new handheld air impulse tonometer(Pulsair, Keeler), the intraocular pressures of 147 eyes of 80 men and women at the age range of 9 to 82 year without corneal opacity or corneal edema were measured with the Goldmann applanation tonometer as well as noncontact air impulse tonometer. The IOPs measured with both tonometer were compared to evaluate the correlation coefficiency. The correlation coefficiency between two instruments is 0.89. Therefore, the new type of noncontact tonometer could be useful for clinical applications due to its accuracy, simplicity, painlessness, portability, and repeatability-especially at glaucoma screening programs.
