    Glaucoma is a leading cause of blindness, with elevated intraocular pressure (IOP) being the only modifiable risk factor for its management.

  • 2

    Goldmann applanation tonometry (GAT) is the gold standard for IOP measurement, but it requires corneal contact and anesthesia.

  • 3

    Non-contact tonometry (NCT) uses air to measure IOP and generally shows higher readings than GAT, especially at elevated IOP levels.

  • 4

    Trans-palpebral tonometry (TPT) measures IOP through the eyelid, offering a non-contact, comfortable alternative suitable for various patients.

  • 5

    The study evaluates the reliability and agreement of IOP measurements across GAT, NCT, and TPT using statistical analysis methods.
