In tertiary hospitals, IOP screening is an important tool to confirm glaucomatous eyes. Inaccurate measurements may lead to missed diagnosis or false positive results that may affect patients' quality of life.~There are many devices produced to measure IOP, the commonest one is Goldman contact tonometry, the aim of this study is to compare the results of new developed tonometers to the standard applanation tonometer.
Monitoring the intraocular pressure (IOP) is one of the most important tests used in follow-up among glaucoma suspects and confirmed glaucomatous patients.
