If a patient's intraocular pressure (IOP) reads 10 mm Hg OD and 24 mm Hg OS, what should you do next?

The correct course of action is to recheck the pressure in the left eye (OS) twice. This is essential because an intraocular pressure reading of 24 mm Hg is higher than the normal range, which typically does not exceed 21 mm Hg. Elevated IOP can indicate potential glaucoma or other ocular conditions that require further evaluation.

By choosing to recheck the pressure in the left eye specifically, you are ensuring that the reading is accurate and not influenced by transient factors like patient posture or corneal conditions that could affect the tonometry results. If the second reading is consistently high, it provides crucial information for the doctor to consider in the diagnosis and management of the patient's eye health.

Rechecking twice allows for confirmation, as single readings can sometimes produce false results due to various factors. This helps to ensure that an appropriate response is based on accurate and reliable data, promoting better patient outcomes.
