Intraocular pressure (IOP) assessment is a valuable skill for any physician working in the emergency room. Measuring the IOP digitally (when the examiner uses his fingers to evaluate a patient's IOP) or with a simple inexpensive tonometer can aid in the diagnosis of vision-threatening ocular conditions (figures 1 and 2). The following case illustrates the usefulness of this examination in the workup of a young patient presenting with severe headache.
