If the NCT reading is over a certain threshold, what should you do next?

In cases where the Non-Contact Tonometry (NCT) reading exceeds the predetermined threshold, the appropriate response is to select the 30-60 button and repeat the test. This is valuable because the initial measurement could be influenced by various factors, such as patient anxiety, improper positioning, or even transient fluctuations in intraocular pressure. Retesting allows for the collection of a more reliable and accurate assessment of the patient’s intraocular pressure.

By confirming elevated readings through a repeat test, you can better determine if there is truly a concern that needs to be addressed, or if the initial reading was an anomaly. This procedure parallels the principle of verification in medical testing, which emphasizes the need for accuracy before making any clinical decisions.

While informing the patient or referring them to an ophthalmologist may be important steps depending on the results and clinical judgment, they should ideally follow confirmed findings rather than the initial high reading alone. Documenting the reading and proceeding with other tests is also essential, but without first retesting, the results may not accurately represent the patient's condition. Thus, repeating the test ensures that any next steps taken are based on solid evidence.
