Area of Science:

  • Ophthalmology
  • Biomedical Engineering

Background:

  • Intraocular pressure (IOP) measurement is crucial for diagnosing and managing glaucoma.
  • Non-contact tonometry offers a potentially more comfortable and efficient method for IOP assessment compared to traditional methods.

Purpose of the Study:

  • To evaluate the accuracy and reliability of the Pulsair non-contact tonometer.
  • To compare Pulsair measurements against the established Goldmann applanation tonometer.

Main Methods:

  • Accuracy was assessed by comparing Pulsair measurements with Goldmann tonometry in 101 eyes.
  • Reliability (reproducibility) was evaluated using measurements from 24 eyes.

Main Results:

  • The Pulsair non-contact tonometer showed high accuracy when compared to Goldmann tonometry.
